| According to McKinsey & Company, the U.S. manufacturing industry represents only 11 percent of U.S. gross domestic product (GDP) and eight percent of direct employment, yet it "makes a disproportionate economic contribution, including 20 percent of the nation’s capital investment, 35 percent of productivity growth, 60 percent of exports, and 70 percent of business R&D spending."<ref name="CarrDeliver22">{{cite web |url=https://www.mckinsey.com/capabilities/operations/our-insights/delivering-the-us-manufacturing-renaissance |title=Delivering the US manufacturing renaissance |author=Carr, T.; Chewning, E.; Doheny, M. et al. |work=McKinsey & Company |date=29 August 2022 |accessdate=24 March 2023}}</ref> These categories of economic contribution are important as many of them indirectly point to how the work of [[Laboratory|laboratories]] is interwoven within the manufacturing industry. As we'll discuss later in this chapter, manufacturing-based laboratories primarily serve three roles: research and development (R&D), pre-manufacturing and manufacturing, and post-production regulation and security (e.g., through exports and trade). We can be sure that if U.S. manufacturers' efforts represent huge chunks of total business R&D spending, trade, and capital expenditure (capex), a non-trivial amount of laboratory effort is associated with that spending. Why? Because R&D, trade, and manufacturing [[quality control]] (QC) activities rarely can occur without laboratories backing up their work.<ref>{{Cite journal |last=Ischi |first=H.

| Labs in the manufacturing sector provide vital services, including but not limited to [[quality assurance]] (QA), QC, production control, regulatory trade control (e.g., authenticity and adulteration), safety management, label claim testing, and packaging analysis. These activities occur in a wide array of manufacturing industries.

| If you've ever used a sophisticated two-part epoxy adhesive to repair a pipe crack, used an indoor sun lamp, gotten a lot of mileage out of a pair of leather gloves, received a medical implant, taken a medication, eaten a Twinkie, or ridden on Amtrak, one or more laboratories were involved somewhere in the manufacturing process before using that item. From endless research and testing of prototypes to various phases of quality and safety testing, laboratory science was involved. The importance of the laboratory in manufacturing processes can't be understated.

| In 1852, the ''Putnam's Home Cyclopedia: Hand-Book of the Useful Arts'' was published as a dictionary-like source of scientific terms. Its definition of a laboratory at that time in U.S. history is revealing (for more on the equipment typically described with a laboratory of that time period, see the full definition)<ref name="AntisellPutnamArts52">{{cite book |url=https://books.google.com/books?id=vsI0AAAAMAAJ&pg=PA284 |title=Putnam's Home Cyclopedia: Hand-Book of the Useful Arts |author=Antisell, T. |publisher=George P.

| <blockquote>'''Laboratory'''. The workshop of a chemist. Some laboratories are intended for private research, and some for the manufacture of chemicals on the large scale. Hence it is almost impossible to give a description of the apparatus and disposition of a laboratory which would be generally true of all. A manufacturing laboratory necessarily occupies a large space, while that of the scientific man is necessarily limited to a peculiar line of research. Those who study in organic chemistry have different arrangements than that of the mineral analyst.</blockquote>

| This definition highlights the state of laboratories at the time: typically you either had a small private laboratory for experiments in the name of research and development (R&D) and producing prototype solutions, or you had a slightly larger "manufacturing laboratory" that was responsible for the creation of chemicals, reagents, or other substances for a wider customer base.<ref name="AntisellPutnamArts52" /><ref name="PorterTheChem30">{{cite book |url=https://books.google.com/books?id=zy8aAAAAYAAJ&pg=PA17&dq=manufacturing+laboratory |title=The Chemistry of the Arts; being a Practical Display of the Arts and Manufactures which Depend on Chemical Principles |chapter=Chemistry Applied to the Arts |author=Porter, A.L. |publisher=Carey & Lea |year=1830 |pages=17–18 |accessdate=06 April 2023 |quote=The larger laboratories, or workshops, which are used only in particular branches of business, and the necessary apparatus attached to them, will be considered under the several substances which are prepared in them.

This is best characterized by the transition from the humble apothecary lab to the small-scale manufacturing laboratory before the mid-1800s, to the full-scale pharmaceutical manufacturing lab and facility well beyond the mid-1800s.

| ====1.1.1 From apothecary to small-scale manufacturing laboratory====
| | :[[User:Shawndouglas/sandbox/sublevel10|1. Introduction to materials and materials testing laboratories]] |
| A critical area to examine in relation to the evolution of manufacturing laboratories involves pharmaceuticals and the apothecary, which is steeped in the tradition of making pharmaceutical preparations, as well as prescribing and dispensing them to customers. The idea of an individual who attempted to make medical treatments dates back to at least to 2000 BC, from which Sumerian documents reveal compounding formulas for various medicinal dosage types.<ref name="AllenAHist11">{{cite journal |url=https://www.perrigo.com/business/pdfs/Sec%20Artem%2011.3.pdf |archiveurl=https://web.archive.org/web/20130128014521/https://www.perrigo.com/business/pdfs/Sec%20Artem%2011.3.pdf |format=PDF |title=A History of Pharmaceutical Compounding |journal=Secundum Artem |author=Allen Jr., L.V. |volume=11 |issue=3 |year=2011 |archivedate=28 January 2013 |accessdate=06 April 2023}}</ref> By 1540, Swiss physician and chemist Paracelsus made a significant contribution to the early apothecary, influencing "the transformation of pharmacy from a profession based primarily on botanic science to one based on chemical science."<ref name="AllenAHist11" /> Thanks to Paracelsus and other sixteenth century practitioners, the concept of the apothecary became more formalized and chemistry-based in the early seventeenth century. With this formalization came the need for the regulation of apothecaries to better ensure the integrity of the profession. For example, the Master, Wardens and Society of the Art and Mystery of Pharmacopolites of the City of London was founded in 1617 through the Royal Charter of James the First, requiring an aspiring apothecary to conduct an apprenticeship or pay a fee, followed by taking an examination proving the individual's knowledge, skill, and science in the art.<ref name="AllenAHist11" /><ref name="Plough97">{{cite journal |url=https://www.google.com/books/edition/Pharmaceutical_Journal/ScDyXwC8McwC?hl=en&gbpv=1&dq=manufacturing+laboratory&pg=PA164&printsec=frontcover |title=The Plough Court Pharmacy |journal=The Pharmaceutical Journal |publisher=Pharmaceutical Society of Great Britain |volume=LVIII |pages=164–7, 247–51 |date=January to June 1897 |accessdate=06 April 2023}}</ref>

| However, despite this sort of early regulation, medical practitioners took exception to apothecaries encroaching upon the medical practitioners' own services, and apothecaries took exception to the untrained and uncertified druggists who were still performing the work of pharmacists. (As it turns out, these sorts of recriminations would continue on in some form or another into the beginning of the twenty-first century, discussed later.) But as an 1897 article from ''The Pharmaceutical Journal'' portrayed, the apothecaries likely wanted to have their cake and eat it too. "[W]hile the apothecaries urged, in the interest of the public, the desirability of a guarantee for the the competences of every person authorised to practise pharmacy," the journal noted, "they also sought, in their own interest, to extend the scope of their medical practice."<ref name="Plough97" /> This led to further debate and changes over time, including British Parliament declaring medicinal preparations as "very proper objects for taxation" in 1783, while at the same time requiring non-apprenticed apothecaries to apply annually for a license. By this time, most apprenticed apothecaries ceased being perceived as mere pharmacists and more as medical practitioners, though the Society's power of conferring medical qualifications, given to them in 1617, were by this point largely lost.<ref name="Plough97" />

| By the end of the eighteenth century, apothecaries and druggists were setting up their own manufacturing laboratories to make chemical and pharmaceutical products. However, these labs were likely still limited in scope. In 1897, ''The Pharmaceutical Journal'' portrayed manufacturing labs as such, in the scope of the growing Plough Court Pharmacy run by William Allen and Luke Howard<ref name="Plough97" />:

| <blockquote>It is, however, difficult to at the present time to realise what must have been the position of a manufacturing chemist in 1797, or to comprehend, without some reflection, how limited was the range of his operations and how much his work was beset with difficulties which are now scarecely conceivable. At that time chemical industry was confined to the production of soap, the mineral acids, and some saline compounds then used in medicine. Among the latter, mercurial preperations held an important place, and some of these appear to have first received attention by the firm of Allen and Howard. The early laboratory account books of the firm mention ammoniacals, caustic potash, borax, argentic nitrate, and cream of tartar, as well as ether, benzoic acid, and refine camphor, which were then articles of the materia medics, citric, tartatic and oxalic acids, etc.</blockquote>

| To be sure, other types of manufacturing were occurring during the rise and dominance of the apothecary, not just pharmaceutical manufacture. But, retrospectively, the pharmaceutical manufacturing lab in general was likely not in the best of shape as the nineteenth century approached. With several changes in Europe and United States in the early 1800s, the apothecary's manufacturing lab arguably saw more formalized and regulated activity, through various releases of pharmacopoeias<ref name="AllenAHist11" /><ref name="AndersonPharm13">{{cite web |url=http://www.histpharm.org/ISHPWG%20UK.pdf |format=PDF |title=Pharmacopoeias of Great Britain |work=A History of the Pharmacopoeias of the World |author=Anderson, S.C. |publisher=International Society for the History of Pharmacy |pages=1–8 |year=2013 |accessdate=06 April 2023}}</ref>, openings of new pharmacy schools (though still limited in scope)<ref name="DCTheEarly18">{{cite journal |url=https://books.google.com/books?id=P3kgAQAAMAAJ&pg=RA2-PA243-IA1&dq=manufacturing+laboratory |title=The Early Days of Pharmaceutical |journal=The Druggists Circular |volume=LXII |issue=6 |pages=244–5 |date=June 1918 |accessdate=06 April 2023}}</ref>, publishing of books<ref name="DCTheEarly18" />, and additional formalization of regulating legislation (such as Britain's Apothecaries Act of 1815).<ref name="Plough97" /> By the time the ''United States Pharmacopeia'' came upon the scene in 1820, the apothecary was viewed as "competent at collecting and identifying botanic drugs and preparing from them the mixtures and preparations required by the physician."<ref name="AllenAHist11" /> Pharmaceutical historian Loyd Allen, Jr. refers to this time period as "a time that would never be seen again," a sort of Golden Age of the apothecary, given the increasingly rapid rate that scientific and technological discoveries were being made soon after, particularly in synthetic organic chemistry.<ref name="AllenAHist11" />

| Of course, the manufacturing lab—pharmaceutical and otherwise—had other issues as well. For example, just because a small-scale experimental R&D process yielded a positive result didn't mean that process was scalable to large-scale manufacturing. "Frequently, things work well on a small scale, and failure results when mass action comes into effect," noted Armour Fertilizer Company's president Charles McDowell in April 1917, while discussing American research methods.<ref name="McDowellAmerican17">{{cite journal |url=https://books.google.com/books?id=8pMPAQAAIAAJ&pg=PA546&dq=manufacturing+laboratory |title=American Research Methods |journal=Journal of the Western Society of Engineers |author=McDowell, C.A. |volume=XXII |issue=8 |year=1917 |pages=546–65 |accessdate=06 April 2023}}</ref> Sometimes a process was sufficiently simple that switching to more robust and appropriate apparatuses was all that was needed to scale up from experiment to full production.<ref name="RobertsonDesulph43">{{cite journal |url=https://books.google.com/books?id=3u01AQAAMAAJ&pg=RA1-PA444&dq=manufacturing+laboratory |title=Desulphuration of Metals |journal=Mechanics' Magazine, Museum, Register, Journal, and Gazette |editor=Robertson, J.C. |volume=38 |date=01 July 1843 |page=444 |accessdate=06 April 2023}}</ref> In other cases, a full-scale manufacturing laboratory process had yet to be developed, let alone the experiments conducted to develop a proof-of-concept solution in the experimental lab.<ref name="JacksonChemical43">{{cite journal |url=https://books.google.com/books?id=hrYxAQAAMAAJ&pg=PA379&dq=manufacturing+laboratory |title=Chemical Salts as Fertilizers |journal=New England Farmer, and Horticultural Register |author=Jackson, C.T. |publisher=Joseph Breck & Co |volume=XXL |issue=48 |page=379 |date=31 May 1843 |accessdate=06 April 2023}}</ref>

| Another challenge the manufacturing lab had was in ensuring the stability of any laboratory manufactured solution. Discussing the British Pharmacopoeia-introduced substance of sulphurous acid for afflictions of the throat, Fellow of the Chemical Society Charles Umney noted the stability considerations of the substance when made in the manufacturing laboratory<ref name="UmneySulphurous69">{{cite journal |url=https://books.google.com/books?id=POkKAAAAYAAJ&pg=PA516&dq=manufacturing+laboratory |title=Sulphurous Acid |journal=Pharmaceutical Journal and Transactions |author=Umney, C. |publisher=John Churchill and Sons |volume=X |issue=IX |pages=516–20 |year=1869 |accessdate=06 April 2023}}</ref>:

| <blockquote>Now the Pharmacopoeia solution (which is about 37 volumes) was designedly made nearly one of saturation at the average summer temperature of this country, and, if one may be excused for making a guess, we described from calculations made from the above data of Bunsen's, and not practically worked out to see whether such a solution could be ordinarily obtained in the manufacturing laboratory without chance of failure, and, when made, be kept without great alteration in the various stages it would have to pass through, even if only from the manufacturer to the wholesale druggist, then to the pharmacists, in whose store it might retain for a year or more, being perhaps placed in a temperature many degrees above the point at which it was saturated, thereby causing expansion, liberation of gas, and inconvenience.</blockquote>

| Difficulties aside, as the 1800s progressed, the resources of a collaboratory manufacturing laboratory were often greater than those of the individual private laboratory, with enterprising businesses increasingly turning to larger labs for greater and more high-quality quantities of materials. For example, in a letter from the Royal Institution of Great Britain, editor William Crookes discussed the discovery of thallium, noting that the manufacturing lab of noted manufacturing chemists Hopkin and Williams were able to prepare chloride of thallium for him from two hundredweight (cwt) in less time than it took Crookes to make 10 pounds of sulfur in his private laboratory.<ref name="CrookesOnThe63">{{cite journal |url=https://books.google.com/books?id=0JHOIc5pHYwC&pg=PA172&dq=manufacturing+laboratory |title=On the Discovery of the Metal Thallium |journal=The Chemical News and Journal of Physical Chemistry |author=Crookes, W. |volume=VII |issue=175 |pages=172–6 |date=April 1863 |accessdate=06 April 2023}}</ref> This trend would continue into the late 1800s, for pharmaceutical and other manufactured goods.

| Reading for a meeting at the Kings County Pharmaceutical Society of Ohio, Charles E. Parker had the following to say about the state of the apothecary-turned-pharmacist in 1896, which fully highlights the transition from small-scale private to larger-scale industrial manufacturing of pharmaceuticals<ref name="ParkerSomeAsp96" />:
| |
| | |
| <blockquote>The modern pharmacist succeeds to all the responsibilities and obligations of the ancient apothecary without opposition, but his utmost efforts have not preserved to him his inheritance of former privileges and emoluments ... Technical skill is of no use to the professional side of pharmacy unless it is used, and used for the public welfare as well as that of its possessor. The dispenser is the ''typical'' pharmacist. But where in former years his sphere included many activities and much manipulative expertness in the preparation of drugs, and even the production of many of them, the midern tendancy is for him to become a mere compounder and dispenser. Of course he is expected to know how, but actually is seldom required to perform the operations once a matter of constant routine. Step by step the productive processes of his little laboratory have been transferred to the works of large manufacturers. Year by year the pharmaceutical improvements and useful inventions which would once have conferred reputation and profit upon the dispensing pharmacies where they originated, have found a better market through these same manufacturers ... In addition, it is to be considered that some of the requisites of modern pharmacy are of a nature involving the use of expensive machinery and large plant, which places their production quite beyond the reach of the pharmacy.</blockquote>

| Writing for the ''Pharmaceutical Review'' in 1897, editor Dr. Edward Kremers penned an editorial on the role of the manufacturing laboratory in the growing pharmaceutical industry, noting that "[d]uring the past hundred years a most remarkable industrial revolution has taken place," and that pharmacy was also victim to that, lamenting that the apothecaries of the beginning of the century—along with the druggists of 1897—had largely become "relics of the past."<ref name="KremersTheManu97">{{cite journal |url=https://books.google.com/books?id=4BU4AQAAMAAJ&pg=PA61&dq=manufacturing+laboratory |title=The Manufacturing Laboratory in the Household of Pharmacy |journal=Pharmaceutical Review |author=Kremers, E. |volume=15 |issue=4 |pages=61–7 |date=April 1897 |accessdate=12 April 2023}}</ref> Kremers also touched upon another complaint popular at the time: that of pharmacy as a money-making venture.<ref name="TWDDrugClerks02" /><ref name="KremersTheManu97" /> In his editorial, Kremers says:
| |
| | |
| <blockquote>It is a hope cherished by some that higher education will revolutionize pharmacy of today and lift her out of her present unenviable situation. The manufacturing industries, however, have revolutionized pharmacy of fifty years ago and are to no small extent coresponsible for the present state of affairs. The pharmaceutical profession as a whole is justified in asking what a particular branch is doing for the general good. Is the pharmaceutical manufacturer in the erection of his buildings, in the equipment of his laboratories and in the selection of his working force simply bent upon making so many thousands of dollars a paying investment, viewed from a merely commercial standpoint, or are his doings influenced to some extent to at least by higher than purely necessary motives.</blockquote>
| |
| | |
| By the early years of 1900, recognition of the sea-level change to the apothecary, pharmacist, and manufacturing laboratory had arguably gained traction, and by 1920 it was largely accepted<ref name="BealAward19">{{cite journal |url=https://books.google.com/books?id=GQlOAAAAMAAJ&pg=PA475&dq=manufacturing+laboratory |title=Award of the Joseph B. Remington Honor Medal |journal=The Midland Druggist and Pharmaceutical Review |author=Diner, J.; Beal, J.H. |volume=LIII |issue=12 |pages=475–9 |date=December 1919 |accessdate=12 April 2023}}</ref>. Writing for ''The Rocky Mountain Druggist'' in 1908, pharmaceutical doctor Geo H. Meeker laid it out in no uncertain terms:
| |
| | |
| <blockquote>Large manufacturing establishments can, for the most part, furnish the druggist at lower prices, with better authentic goods than he himself could produce, assay and guarantee. The inevitable result is that the druggist of today purchases finished products rather than raw materials as did the apothecary of yesterday. It is obvious that a large manufacturing establishment, conducted on ethical lines, employing a complete corps of specialists, buying raw materials to the best advantage and by assay only, making preparations on a large and intelligent technical scale and testing and assying the finished products, does a work that is too immense in its scope for the individual apothecary ... Our present remnant of the drug store laboratory is, as in the past, essentially a manufacturing laboratory. It is of limited and rapidly vanishing scope because the small local laboratory man cannot successfully compete with his rivals, the great and highly-organized factories.</blockquote>

| Similar comments were being made by Pearson in 1911<ref name="PearsonThePrep11" />, Thiesing in 1915<ref name="Thiesing15">{{cite journal |url=https://books.google.com/books?id=b_5EAQAAMAAJ&pg=PA1203&dq=manufacturing+laboratory |title=Proceedings of the Joint Session of the Commercial Section and Section on Education and Legislation - Chairman Thiesing's Address |journal=The Journal of the Americam Pharmaceutical Association |author=Thiesing, E.H. |volume=IV |issue=10 |pages= |date=October 1915 |accessdate=12 April 2023}}</ref>, and Beal in 1919.<ref name="BealAward19" /> Beal in particular spoke solemnly of the transition, largely complete by the time of his acceptance of the Joseph P. Remington Honor Medal in 1919. Speaking of Remington and his experiences in pharmacy, until his death in 1918, Beal said<ref name="BealAward19" />:
| |
| | |
| <blockquote>Professor Remington's professional experience bridged the space between two distinct periods of pharmaceutical development. When he began his apprenticeship the apothecary, as he was then commonly called, was the principal manufacturer as well as the purveyor of medical supplies ... He lived to see the period when the apothecary ceased to be the principal producer of medicinal compounds and became mainly the purveyor of preparations manufactured by others, and when the medicinal agents in most common use assumed a character that required for the successful production the resources of establishments maintained by large aggregations of capital and employing large numbers of specially trained workers.
| |
| | |
| To those who knew him intimately it was evident that although Professor Remington did not welcome the passing of the manufacturing functions of the apothecary to the large laboratory, he at length came to realize that such a change was inevitable, that it was but a natural step in the process of social evolution, and that the logical action of the apothecary was not to resist that which he could neither prevent nor change, but to readjust himself to the new conditions.</blockquote>

| | |
| Of course, by then, the rise of the industrial research lab within large-scale manufacturing enterprises was in full swing.
| |
| | |
| ====1.1.3 The rise of the industrial research lab within large-scale manufacturing, and today's manufacturing landscape====
| |
| Like the small, privately owned manufacturing labs evolving to large-scale company-run manufacturing labs, so did the research processes of prior days. The individual tinkering with research in their private laboratory and making small batches of product gave way to a collective of individuals with more specialized talents cooperatively working in a large industrial manufacturing center towards a common, often complex research goal, i.e., within the industrial research laboratory.<ref name="MeesTheOrg20">{{cite book |url=https://books.google.com/books?id=rDIuAAAAYAAJ&printsec=frontcover&dq=industrial+research+laboratories |title=The Organization of Industrial Scientific Research |chapter=Chapter 1: Introduction |author=Mees, C.E.K. |publisher=McGraw-Hill Book Company, Inc |pages=4–10 |year=1920 |accessdate=12 April 2023}}</ref><ref name="BoydPutting24">{{cite journal |url=https://books.google.com/books?id=lYkiAQAAMAAJ&pg=RA23-PA22&dq=industrial+research+laboratories |title=Putting Research to Work |journal=A.E.C.

| |
| | |
| But what drove the advance of the industrial research lab? As the National Research Council pointed out in 1940, "individuals working independently could not, for very long, provide the technical and scientific knowledge essential to a rapidly developing industrial nation."<ref name="NRCRsearch40">{{cite book |url=https://nap.nationalacademies.org/read/20233/chapter/4#34 |title=Research—A National Resource, II—Industrial Research |author=National Research Council |publisher=United States Government Printing Office |date=December 1940 |accessdate=13 April 2023}}</ref> Newly emerging industries had a need for new knowledge to feed their growth, and they proved to be the early adopters of establishing separate research departments or divisions in their businesses, unlike businesses in long-established industries. The First World War was also responsible for driving organized research efforts in various industries to solve not only wartime problems but also plant the seed of development in peacetime industries. By 1920, two-thirds of all research workers surveyed by the National Research Council were employed in the emerging electrical, chemical, and rubber industries, though the overall adoption of industrial research approaches was still limited across all companies.<ref name="NRCRsearch40" />
| |
| | |
| In 1917, the previously mentioned Charles McDowell presented his view of American research and manufacturing methods of his time, referring to research as "diligent inquiry."<ref name="McDowellAmerican17" /> In his work, McDowell stated three types of research that leads up to the manufacturing process: pure scientific inquiry, industrial research, and factory research. He noted that of pure scientific inquiry, little thought is typically given to whether the research—often conducted by university professors—will have any real commercial value, though such value is able to emerge from this fundamental research. As for factory research, McDowell characterized it as full-scale factory-level operations that range from haphazard approaches to well-calculated contingency planning, all of which could make or break the manufacturing business.
| |
| | |
| In regards to the middle category of industrial research, McDowell made several observations that aptly described the state of manufacturing research in the early 1900s. He noted that unlike pure scientific inquiry, industrial research had commercial practicality as a goal, often beginning with small-scale experiments while later seeking how to reproduce those theoretical results into large-scale manufacturing. He also reiterated his point about needing to "have good backing" financially. "The larger manufacturer maintains his own staff and equipment to carry out investigations along any line that may seem desirable," he said, "but the smaller industries are not able to support an establishment and must rely on either consulting engineers or turn their problems over to some equipped public or private laboratory to solve."<ref name="McDowellAmerican17" />
| |
| | |
| In his 1920 book ''The Organization of Industrial Scientific Research'', Mees presented these three types of research somewhat similarly, though in the context of the industrial laboratory and its operations. Mees argued that industrial laboratories could be classified into three divisions<ref name="MeesTheOrg20" />:
| |
| | |
| *Laboratories "working on pure theory and the fundamental sciences associated with the industry," aligning in part with McDowell's "pure scientific inquiry";
| |
| *Work laboratories "exerting analytical control over materials, processes and product," aligning slightly with McDowell's "factory research" but more akin to the modern quality control lab; and
| |
| *Industrial laboratories "working on improvements in product and in processes," aligning with McDowell's "industrial research."
| |
| | |
| Mees argued in particular that those industrial research laboratories that simply improve products and processes were not doing enough; they should, necessarily, also direct some of their goals towards more fully understanding the fundamental and underlying theory of the topic of research.<ref name="MeesTheOrg20" /> In other words, Mees suggested that those labs simply working on theoretical and fundamental science research, as well as those labs conducting industrial research to improve products and processes, shouldn't necessarily function in separate vacuums. "Research work of this fundamental kind involves a laboratory very different from the usual works laboratory and also investigators of a different type from those employed in a purely industrial laboratory," he noted. Of course, this hybrid approach to fundamental and industrial research was largely reserved for the largest of manufacturers, and solutions were needed for smaller manufacturing endeavors. Here, like McDowell in 1917, Mees argued for smaller businesses with limited resources adopting both cooperative laboratory (those businesses that pool resources together for a fully supported research laboratory) and consulting laboratory (a third-party lab with the resources to fully study a problem, undertake investigations, model a manufacturing process, and implement that process into its client's factory, all for a fee) approaches.<ref name="MeesTheOrg20" /> With such solutions, the industrial research laboratory continued to take on a new level of complexity to address emerging industry needs, far from the humble origins of an early nineteenth-century manufacturing laboratory.
| |
| | |
| This growth or industrial research would continue onward from the twentieth century into the twenty-first century. In 1921, some 15 companies maintained research groups of more than 50 people; by 1938, there were 120 such businesses.<ref name="NRCRsearch40" /> By the 1990s, "the share of funding for basic research provided by industry actually grew from 10 percent to 25 percent of the national total, even though basic research accounted for just 5-7 percent of total R&D expenditures by industry."<ref name="UsselmanResearch13">{{cite web |url=https://economics.yale.edu/sites/default/files/usselman_paper.pdf |title=Research and Development in the United States since 1900: An Interpretive History |author=Usselman, S.W. |publisher=Yale University |date=11 November 2013 |accessdate=13 April 2023}}</ref> This trend of large research groups continues today, though with the recognition that smaller teams may still have advantages. In a 2019 article in the ''Harvard Business Review'', Wang and Evans recognize "large teams as optimal engines for tomorrow’s largest advances," while smaller research teams are better poised to ask disruptive questions and make innovative discoveries.<ref name="WangResearch19">{{cite web |url=https://hbr.org/2019/02/research-when-small-teams-are-better-than-big-ones |title=Research: When Small Teams Are Better Than Big Ones |work=Harvard Business Review |authors=Wang, D.; Evans, J.A. |date=21 February 2019 |accessdate=13 April 2023}}</ref>

| ===1.2 Laboratory roles and activities in the industry===
| |
| Today, the "manufacturing laboratory" is a complex entity that goes beyond the general idea of a lab making or researching things. Many of the historical aspects discussed prior still hold today, but other aspects have changed. As indicated in the introduction, the world of manufacturing encompasses a wide swath of industries and sub-industries, each with their own nuances. Given the nuances of pharmaceutical manufacturing, food and beverage development, petrochemical extraction and use, and other industries, it's difficult to make broad statements about manufacturing laboratories in general. However, the rest of this guide will attempt to do just that, while at times pointing out a few of those nuances found in specific industries.
| |
| | |
| The biggest area of commonality is found, unsurprisingly, in the roles manufacturing-based labs play today, as well as the types of lab activities they're conducting within those roles. These roles prove to be important in the greater scheme of industry activities, in turn providing a number of benefits to society. As gleaned from prior discussion, as well as other sources, these laboratory roles can be broadly broken into three categories: research and development (R&D), pre-manufacturing and manufacturing, and post-production regulation and security. Additionally, each of these categories has its own types of laboratory activities.
| |
| | |
| The scientific disciplines that go into these laboratory roles and activities is as diverse as the manufacturing industries and sub-industries that make up the manufacturing world. For example, the
| |
| food and beverage laboratory taps into disciplines such as [[biochemistry]], [[biotechnology]], [[chemical engineering]], [[chemistry]], fermentation science, materials science, [[microbiology]], molecular gastronomy, and nutrition.<ref name="NolletHand15">{{cite book |url=https://books.google.com/books?id=KtAdCgAAQBAJ&printsec=frontcover |title=Handbook of Food Analysis (Two Volume Set) |editor=Nollet, L.M.L.; Toldrá, F. |publisher=CRC Press |edition=3rd |pages=1568 |year=2015 |isbn=9781482297843}}</ref><ref name="NielsenFood15">{{cite book |url=https://books.google.com/books?id=i5TdyXBiwRsC&printsec=frontcover |title=Food Analysis Laboratory Manual |author=Nielsen, S. |publisher=Springer |pages=177 |edition=2nd |year=2015 |isbn=9781441914620}}</ref><ref name="DouglasTheLabs22">{{cite book |url=https://www.limswiki.org/index.php/LII:The_Laboratories_of_Our_Lives:_Labs,_Labs_Everywhere!/Labs_by_industry:_Part_2 |chapter=Labs by industry: Part 2 |title=The Laboratories of Our Lives: Labs, Labs Everywhere! |author=Douglas, S.E. |publisher=LIMSwiki |edition=2nd |date=July 2022 |accessdate=13 April 2023}}</ref><ref>{{Cite book |last=Bhandari, B.; Roos, Y.H. |date=2012 |editor-last=Bhandari |editor-first=Bhesh |editor2-last=Roos |editor2-first=Yrjö H. |title=Food Materials Science and Engineering |chapter=Chapter 1: Food Materials Science and Engineering: An Overview |publisher=Wiley-Blackwell |place=Chichester, West Sussex, UK ; Ames, Iowa |pages=1–25 |isbn=978-1-4051-9922-3}}</ref> However, the paper and printing industry taps into disciplines such as biochemistry, [[biology]], chemistry, environmental science, engineering, forestry, and physics.<ref name="BajpaiEnviro10">{{cite book |url=https://books.google.com/books?id=zjEeUpwepFMC&printsec=frontcover |title=Environmentally Friendly Production of Pulp and Paper |chapter=Chapter 2: Overview of Pulp and Papermaking Processes |author=Bajpai, P. |publisher=John Wiley & Sons |pages=8–45 |year=2010 |isbn=9780470528105 |accessdate=13 April 2023}}</ref><ref>{{Citation |last=Nykänen |first=Panu |date=2018 |editor-last=Särkkä |editor-first=Timo |editor2-last=Gutiérrez-Poch |editor2-first=Miquel |editor3-last=Kuhlberg |editor3-first=Mark |title=Research and Development in the Finnish Wood Processing and Paper Industry, c. 1850–1990 |url=http://link.springer.com/10.1007/978-3-319-94962-8_3 |work=Technological Transformation in the Global Pulp and Paper Industry 1800–2018 |publisher=Springer International Publishing |place=Cham |volume=23 |pages=35–64 |doi=10.1007/978-3-319-94962-8_3 |isbn=978-3-319-94961-1 |accessdate=2023-04-13}}</ref> By extension, the reader can imagine that these and other industries also have a wide variety of laboratory techniques associated with their R&D, manufacturing, and post-production activities.
| |
| | |
| The following subsections more closely examine the three roles manufacturing-based labs can play, as well as a few examples of lab-related activities found within those roles.
| |
| | |
| ====1.2.1 R&D roles and activities====
| |
| The National Institute of Standards and Technology (NIST) and its Technology Partnerships Office offer a detailed definition of manufacturing-related R&D as an activity "aimed at increasing the competitive capability of manufacturing concerns," and that "encompasses improvements in existing methods or processes, or wholly new processes, machines or system."<ref name="NISTDefin19">{{cite web |url=https://www.nist.gov/tpo/definition-manufacturing-related-rd |title=Definition of Manufacturing-related R&D |author=Technology Partnerships Office |publisher=National Institute of Standards and Technology |date=31 July 2019 |accessdate=14 April 2023}}</ref> They break this down into four different technology levels<ref name="NISTDefin19" />:
| |
| | |
| *Unit process-level technologies that create or improve manufacturing processes,
| |
| *Machine-level technologies that create or improve manufacturing equipment,
| |
| *Systems-level technologies for innovation in the manufacturing enterprise, and
| |
| *Environment- or societal-level technologies that improve workforce abilities and manufacturing competitiveness.
| |
| | |
| Obviously, this definition applies to actual development of and innovation towards methods of improving and streamlining manufacturing processes. However, this same concept can, in part, can be applied to the actual products made in a manufacturing plant. Not only does product-based R&D focus on improving "existing methods and processes," but it also focuses on "manufacturing competitiveness" by developing new and innovating existing products that meet end users' needs. Laboratories play an manufacturing-based R&D laboratories play an important role in this regard.
| |
| | |
| The laboratory participating in this role is performing one or more tasks that relate to the development or improvement of a manufactured good. This often leads to a commercial formulation, process, or promising insight into a product. The R&D lab may appear outside the manufacturing facility proper, but not necessarily always. Some manufacturing companies may have an entire research complex dedicated to creating and improving some aspect of their products.<ref name="MonBreak16">{{cite web |url=https://ir.mondelezinternational.com/news-releases/news-release-details/mondelez-international-breaks-ground-new-research-development |title=Mondelez International Breaks Ground for New Research & Development Center in Poland |publisher=Mondelez International |date=08 June 2016 |accessdate=13 April 2023}}</ref> Other companies may take their R&D to a third-party consulting lab dedicated to conducting development and formulation activities for manufacturers.<ref name="BSCommForm">{{cite web |url=https://www.bevsource.com/news/why-you-need-commercial-formula |title=Why You Need A Commercial Formula |publisher=BevSource |date=13 August 2022}}</ref><ref name="GudeSol19">{{cite book |chapter=Solutions Commonly Applied in Industry and Outsourced to Expert Laboratories |title=Food Contact Materials Analysis: Mass Spectrometry Techniques |author=Gude, T. |editor=Suman, M. |publisher=Royal Society of Chemistry |doi=10.1039/9781788012973-00245 |isbn=9781788017190 |year=2019}}</ref> Industrial research activities aren't confined to manufacturers, however. Some higher education institutions provide laboratory-based research and development opportunities to students engaging in work-study programs, often in partnership with some other commercial enterprise.<ref name="HartFoodBev">{{cite web |url=https://www.hartwick.edu/about-us/center-for-craft-food-and-beverage/ |title=Hartwick College Center for Craft Food & Beverage |publisher=Hartwick College |accessdate=13 April 2023}}</ref>
| |
| | |
| The following types of lab-related activities may be associated with the R&D role:
| |
| | |
| '''Overall product development and innovation''': Jain ''et al.'' noted in their book on managing R&D activities that in 2010, 60 percent of U.S. R&D was focused on product development, while 22 percent focused on applied research and 18 percent on basic research. However, they also argue that any R&D lab worth its weight should have a mix of these activities, while also including customer participation in the needs assessment and innovation activities that take place in product development and other research activities. Jain ''et al.'' define a manufacturer's innovation activities as "combining understanding and invention in the form of socially useful and affordable products and processes."<ref>{{Cite book |url=https://books.google.com/books?id=nSgebaFKwvMC&pg=PA8 |last=Jain |first=Ravi |last2=Triandis |first2=Harry Charalambos |last3=Weick |first3=Cynthia Wagner |date=2010 |title=Managing research, development and innovation: Managing the unmanageable |chapter=Chapter 1: R&D Organizations and Research Categories |edition=3rd |publisher=Wiley |place=Hoboken, N.J |pages=8 |isbn=978-0-470-40412-6}}</ref> As the definition denotes, newly developed products ("offerings") and processes (usually which improve some level of efficiency and effectiveness) come out of innovation activities. Additionally, platforms that turn existing components or building blocks into a new derivative offering (e.g., a new model or "generation" of product), as well as "solutions that solve end-to-end customer problems," can be derived from innovation. Those activities can focus on more risky radical innovation to a new product or take a more cautious incremental approach to improvements on existing products.<ref>{{Cite book |url=https://books.google.com/books?id=nSgebaFKwvMC&pg=PA240 |last=Jain |first=Ravi |last2=Triandis |first2=Harry Charalambos |last3=Weick |first3=Cynthia Wagner |date=2010 |title=Managing research, development and innovation: Managing the unmanageable |chapter=Chapter 12: Models for Implementing Incremental and Radical Innovation |edition=3rd |publisher=Wiley |place=Hoboken, N.J |pages=240–241 |isbn=978-0-470-40412-6}}</ref>

| In the end, reformulation is a means for improving impacts on the end user, the environment, or even the long-term budget of the manufacturer. The type of lab activities associated with reformulation largely varies by product; the laboratory methods used to reformulate gasoline may be quite different from those in a food and beverage lab. Reformulation can also be a complicated process, as found with pharmaceutical products. The reformulated product "must have the same therapeutic effect, stability, and purity profile" as the original, while maintaining pleasing aesthetic qualities to the end user. Adding to the problem is regulatory approval times of such pharmaceutical reformulations.<ref name=":1" />

| '''Nondestructive testing and materials characterization''': Raj ''et al.'' describe nondestructive testing (NDT) as "techniques that are based on the application of physical principles employed for the purpose of determining the characteristics of materials or components or systems and for detecting and assessing the inhomogeneities and harmful defects without impairing the usefulness of such materials or components or systems."<ref name=":7">{{Cite book |last=Raj, B.; Jayakumar, T.; Thavasimuthu, M. |year=2014 |title=Practical Non-Destructive Testing |url=https://archive.org/details/practicalnondest0000rajb |edition=Ninth Reprint, 3rd |publisher=Narosa Publishing House Pvt.

| '''Stability, cycle, and challenge testing''': Multiple deteriorative catalysts can influence the shelf life of a manufactured product, from microbiological contaminants and chemical deterioration to storage conditions and the packaging itself. As such, there are multiple approaches to taming the effects of those catalysts, from introducing additives to improving the packaging.<ref name="SubramaniamTheStab16">{{Cite book |date=2016 |editor-last=Subramaniam |editor-first=Persis |title=The stability and shelf life of food |url=https://www.worldcat.org/title/mediawiki/oclc/956922925 |series=Woodhead Publishing Series in Food Science, Technology and Nutrition |edition=Second edition |publisher=Elsevier/WP, Woodhead Publishing |place=Amsterdam |isbn=978-0-08-100436-4 |oclc=956922925}}</ref> However, stability, cycle, and challenge testing must be conducted on many products to determine what deleterious factors are in play. The analytical techniques applied in stability, cycle, and challenge testing will vary based on, to a large degree, the product matrix and its chemical composition.<ref name="SubramaniamTheStab16" /> Microbiological testing is sure to be involved, particularly in challenge testing, which simulates what could happen to a product if contaminated by a microorganism and placed in a representative storage condition.<ref>{{Cite book |last=Komitopoulou, E. |date=2011 |editor-last=Kilcast |editor-first=David |editor2-last=Subramaniam |editor2-first=Persis |title=Food and beverage stability and shelf life |url=https://www.worldcat.org/title/mediawiki/oclc/838321011 |chapter=Microbiological challenge testing of food |series=Woodhead Publishing Series in Food Science, Technology and Nutrition |publisher=WP, Woodhead Publ |place=Oxford |pages=507–526 |isbn=978-0-85709-254-0 |oclc=838321011}}</ref><ref name=":6">{{Cite book |last=Chen, S.-C. |date=2018 |editor-last=Warne |editor-first=Nicholas W. |editor2-last=Mahler |editor2-first=Hanns-Christian |title=Challenges in Protein Product Development |url=https://books.google.com/books?id=LyVhDwAAQBAJ&pg=PA264&dq=Stability,+cycle,+and+challenge+testing |chapter=Chapter 12: Container Closure Integrity Testing of Primary Containers for Parenteral Products |series=AAPS Advances in the Pharmaceutical Sciences Series |language=en |publisher=Springer International Publishing |place=Cham |volume=38 |pages=257–290 |doi=10.1007/978-3-319-90603-4 |isbn=978-3-319-90601-0}}</ref> Calorimetry, spectrophotometry, spectroscopy, and hyperspectral imaging may be used to properly assess color, particularly when gauging food quality.<ref name="SubramaniamTheStab16" /> Other test types that may be used include water content, texture, viscosity, dispersibility, glass transition, and gas chromatography.<ref name="SubramaniamTheStab16" /> In the end, the substrate being examined will be a major determiner of what kind of lab methods are used. The lab method chosen for stability, cycle, and challenge testing should optimally be one that errs on the side of caution and is appropriate to the test, even if it takes longer. As Chen notes: "A longer test cycle is less a concern for stability protocol as the study typically has a limited number of samples. Applying a less reliable method to the limited number of samples in a stability study can be problematic."<ref name=":6" />

| '''Packaging analysis and extractable and leachable testing''': Materials that contact pharmaceuticals, foods and beverages, cosmetics, and more receive special regulatory consideration in various parts of the world. This includes alloys, bioplastics, can coatings, glass, metals, regenerated cellulose materials, paper, paperboard, plastics, printing inks, rubber, textiles, waxes, and woods.<ref>{{Cite book |date=2021 |editor-last=Baughan |editor-first=Joan Sylvain |title=Global Legislation for Food Contact Materials |url=https://www.worldcat.org/title/mediawiki/oclc/on1272898230 |series=Woodhead Publishing Series in Food Science, Technology and Nutrition |edition=Second edition |publisher=Woodhead Publishing |place=Oxford |isbn=978-0-12-821181-6 |oclc=on1272898230}}</ref> As such, meeting regulatory requirements and making inroads with packaging development can be a complicated process. Concerns of chemicals and elements that can be extracted or leach into sensitive products add another layer of complexity to developing and choosing packaging materials for many manufactured goods. This requires extractable and leachable testing at various phases of product development to ensure the packaging selected during formulation is safe and effective.<ref name=":6" /><ref name="BaloghTesting11">{{cite journal |url=https://www.chromatographyonline.com/view/testing-critical-interface-leachables-and-extractables |title=Testing the Critical Interface: Leachables and Extractables |author=Balogh, M.P. |journal=LCGC North America |volume=29 |issue=6 |pages=492–501 |year=2011}}</ref> Extractable and leachable testing for packaging could involve a number of techniques ranging from gas and liquid chromatography to ion chromatography and inductively coupled plasma mass spectrometry.<ref name="LAExtract">{{cite web |url=https://leeder-analytical.com/extractables-and-leachables-testing/ |title=Extractables and leachables testing (E&Ls) |publisher=Leeder Analytical |accessdate=14 April 2023}}</ref>

| ====1.2.2 Pre-manufacturing and manufacturing roles and activities====
| |
| The laboratory participating in these roles is performing one or more tasks that relate to the preparative (i.e., pre-manufacturing) or [[quality control]] (QC; i.e., manufacturing) activities of production. An example of preparative work is conducting allergen, calorie, and nutrition testing for a formulated food and beverage product. Calorie and nutrition testing—conducted in part as a means of meeting regulation-driven labeling requirements—lands firmly in the role of pre-manufacturing activity, most certainly after commercial formulation and packing requirements have been finalized but before the formal manufacturing process has begun.<ref name="BSNutTest">{{cite web |url=https://www.bevsource.com/news/what-do-i-need-know-about-nutrition-testing-my-beverage-brand |title=What Do I Need To Know About Nutrition Testing for My Beverage Brand? |publisher=BevSource |date=14 April 2023}}</ref> Allergen testing works in a similar fashion, though the manufacturer ideally uses a full set of best practices for food allergen management and testing, from confirming allergens (and correct labeling) from ingredients ordered to performing final production line cleanup (e.g., when a new allergen-free commercial formulation is being made or an unintended contamination has occurred).<ref name="CA80-2020">{{cite web |url=https://www.fao.org/fao-who-codexalimentarius/sh-proxy/en/?lnk=1&url=https%253A%252F%252Fworkspace.fao.org%252Fsites%252Fcodex%252FStandards%252FCXC%2B80-2020%252FCXC_080e.pdf |format=PDF |title=Code of Practice on Food Allergen Management for Food Business Operators, CXC 80-2020 |work=Codex Alimentarius |date=2020 |accessdate=14 April 2023}}</ref> These types of pre-production analyses aren't uncommon to other types of manufacturing, discussed below.
| |
| | |
| As for in-process manufacturing QC, some QC and [[quality assurance]] (QA) methods may already be built into the manufacturing process in-line, not requiring a lab. For example, poka-yoke mechanisms that inhibit, correct, or highlight errors as they occur, as close to the source as possible—may be built in-line to a manufacturing process to prevent a process from continuing should a detectable error occur, or until a certain condition has been reached.<ref name="DanielPoka21">{{cite web |url=https://www.techtarget.com/searcherp/definition/poka-yoke |title=poka-yoke |author=Daniel, D. |work=TechTarget ERP - Definition |date=October 2021 |accessdate=14 April 2023}}</ref><ref>{{Cite book |last=Dogan, O.; Cebeci, U. |date=2021 |editor-last=García Alcaraz |editor-first=Jorge Luis |editor2-last=Sánchez-Ramírez |editor2-first=Cuauhtémoc |editor3-last=Gil López |editor3-first=Alfonso Jesús |title=Techniques, Tools and Methodologies Applied to Quality Assurance in Manufacturing |url=https://link.springer.com/10.1007/978-3-030-69314-5 |chapter=Chapter 1: An Integrated Quality Tools Approach for New Product Development |language=en |publisher=Springer International Publishing |place=Cham |pages=3–22 |doi=10.1007/978-3-030-69314-5 |isbn=978-3-030-69313-8}}</ref> However, despite the value of inline QC/QA, these activities also happen beyond the production line, in the laboratory (discussed further, below).
| |
| | |
| The following types of lab-related activities may be associated with the pre-manufacturing and manufacturing role:
| |
| | |
| '''Various pre-manufacturing analyses''': Also known as pre-production, some level of laboratory activity takes place here. Like the previously mentioned food and beverage industry, the garment manufacturing industry, for example, will have its own laboratory-based pre-production activities, including testing various raw material samples for potential use and quality testing pre-production samples before deciding to go into full production.<ref name="BaukhPreprod20">{{cite web |url=https://techpacker.com/blog/manufacturing/pre-production-processes-in-garment-manufacturing/ |title=Pre-production processes in garment manufacturing |author=Baukh, O. |work=Techpacker |date=14 October 2020 |accessdate=14 April 2023}}</ref> In another example, a manufacturer intending to produce "a new chemical substance for a non-exempt commercial purpose" in the U.S. must submit a pre-manufacture notice to the Environmental Protection Agency (EPA), which must include "test data on the effect to human health or the environment."<ref name="EPAFiling22">{{cite web |url=https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca/filing-pre-manufacture-notice-epa |title=Filing a Pre-manufacture Notice with EPA |work=Reviewing New Chemicals under the Toxic Substances Control Act (TSCA) |publisher=U.S. Environmental Protection Agency |date=26 October 2022 |accessdate=14 April 2023}}</ref> Given this regulatory requirement, some final pre-approval testing much occur to ensure the chemical meets regulatory requirements before full manufacturing processes begin.
| |
| | |
| '''Quality control testing''': While QC testing can appear in multiple manufacturing laboratory roles, it's most noticeable in the pre-manufacturing and manufacturing role. Manufacturers in many industries have set up formal testing laboratories to better ensure that their products conform to a determined set of accepted standards, whether those standards come from a standards-setting organization or are internally derived. QC testing is a multi-pronged approach that includes both non-laboratory and laboratory analyses, whether it is in real-time or periodically during manufacturing activities. The previously mentioned inline poka-yoke mechanisms provide an example of non-laboratory QC activities. However, when rigorous mechanical, chemical, or some other form of testing of a manufactured product is required at different stages of production, a laboratory will be involved. This type of in-process inspection occurs after roughly 10 to 30 percent of products are completed.<ref name="AnjoranBasic10">{{cite web |url=https://qualityinspection.org/quality-control-basics/ |title=Basic Quality Control Concepts |work=QualityInspection.org |author=Anjoran, R. |date=February 2010 |accessdate=20 April 2023}}</ref> Manufacturers can take multiple approaches to QC testing, depending on the circumstances of manufacturing. This includes 100 percent inspection methods, Six Sigma approaches, X-bar charting, total quality management, statistical quality control, Taguchi approaches, and more.<ref name="MalsamQual22">{{cite web |url=https://www.projectmanager.com/blog/quality-control-manufacturing |title=Quality Control in Manufacturing: A Quick Guide |work=ProectManager.com |author=Malsam, W. |date=06 December 2022 |accessdate=20 April 2023}}</ref>
| |
| | |
| The actual types of analyses going on during QC will entirely depend on the material being tested, the functionality of the item, and the intended goal of testing. For example, [[polymerase chain reaction]] (PCR) testing of infant formula for the pathogenic bacterium ''Cronobacter sakazakii''<ref>{{Cite journal |last=Seo |first=K.H. |last2=Brackett |first2=R.E. |date=2005-01 |title=Rapid, Specific Detection of Enterobacter sakazakii in Infant Formula Using a Real-Time PCR Assay |url=https://linkinghub.elsevier.com/retrieve/pii/S0362028X22009000 |journal=Journal of Food Protection |language=en |volume=68 |issue=1 |pages=59–63 |doi=10.4315/0362-028X-68.1.59}}</ref> during production runs is entirely different from periodic Rockwell, Brinell, or Vickers hardness testing of aerospace fasteners.<ref name="RichardsonControl18">{{cite web |url=https://www.aero-mag.com/controlling-product-quality-with-hardness-testing |title=Controlling product quality with hardness testing |author=Richardson, M. |work=Aerospace Manufacturing |date=30 August 2018 |accessdate=20 April 2023}}</ref> NDT and materials testing, discussed in the prior subsection about R&D, can also occur during the various phases of manufacturing, as part of an overall quality control effort.<ref name=":7" />
| |
| | |
| ====1.2.3 Post-production regulation and security roles and activities====
| |
| The laboratory participating in these roles is performing one or more tasks that relate to the post-production examination of products for regulatory, security, or accreditation purposes. Labs are often third parties accrediting a producer to a set of standards, ensuring regulatory compliance, conducting authenticity and adulteration testing, conducting security checks at borders, and applying contamination testing as part of an overall effort to track down contamination sources. In addition to ensuring a safer product, society also benefits from these and similar labs by better holding producers legally accountable for their production methods and obligations.
| |
| | |
| The following types of lab-related activities may be associated with the post-production regulation and security role:
| |
| | |
| '''Authenticity and adulteration testing''': This type of testing is largely conducted to ensure products ingested, injected, inserted, and/or handled by humans and animals are safe to use and authentic to consumer expectations. Anything from food and pharmaceuticals to children's toys and fishing sinkers may be tested to ensure they contain what the manufacturer claims is contained in them. Foods and beverages, for example, are subject to a variety of food supply chain laws and regulations across national and international borders. As such, scientists have developed a number of analytical techniques "to identify foods or food ingredients that are in breach of labeling requirement and may consequently be adulterated." Among these techniques are DNA fingerprinting; visible, ultraviolet, infrared, fluorescence emission, and nuclear magnetic resonance spectroscopy; mass spectrometry; isotopic analysis; [[chromatography]]; [[polymerase chain reaction]]; differential scanning calorimetry; chemometric; and "electric nose and tongue" techniques.<ref>{{Cite book |last=Downey |first=Gerard |date=2016 |title=Advances in Food Authenticity Testing. |url=https://books.google.com/books?id=Q-8QCgAAQBAJ&printsec=frontcover |language=English |publisher=Woodhead Publishing. |place=S.l. |pages=798 |isbn=978-0-08-100233-9 |oclc=1096681184}}</ref><ref>{{Cite journal |last=Tan |first=Choon Hui |last2=Kong |first2=Ianne |last3=Irfan |first3=Umair |last4=Solihin |first4=Mahmud Iwan |last5=Pui |first5=Liew Phing |date=2021 |title=Edible Oils Adulteration: A Review on Regulatory Compliance and Its Detection Technologies |url=https://www.jstage.jst.go.jp/article/jos/70/10/70_ess21109/_article |journal=Journal of Oleo Science |language=en |volume=70 |issue=10 |pages=1343–1356 |doi=10.5650/jos.ess21109 |issn=1345-8957}}</ref> In the United States, certain toys are subject to being tested and certified to the ASTM F963-17 standard by the U.S. Consumer Product Safety Commission (CPSC), with some toys being tested for heavy metals in surface coatings, nitrosamines in rubber, and contaminates in pastes, putties, and gels.<ref>{{Cite web |last=U.S. Consumer Product Safety Commission |title=Toy Safety Business Guidance & Small Entity Compliance Guide |url=https://www.cpsc.gov/Business--Manufacturing/Business-Education/Toy-Safety-Business-Guidance-and-Small-Entity-Compliance-Guide |date=2023 |accessdate=20 April 2023}}</ref> Authenticity and adulteration testing may occur during post-production as part of meeting a manufacturer's regulatory requirements, or it may be conducted at a state or national border as part of a set of international trade rules. In most cases, the testing will be done by a third party laboratory or a regulatory body.
| |
| | |
| '''Accreditation-led testing''': For example, labs optionally accredited to [[LII:FDA Food Safety Modernization Act Final Rule on Laboratory Accreditation for Analyses of Foods: Considerations for Labs and Informatics Vendors|Laboratory Accreditation for Analyses of Foods]] (LAAF) rules are recognized by the FDA as meeting the process requirements of the LAAF program for testing of specific sprouts, eggs, water, and certain foods being considered for import into the country.<ref name="DouglasFDA22">{{cite web |url=https://www.limswiki.org/index.php/LII:FDA_Food_Safety_Modernization_Act_Final_Rule_on_Laboratory_Accreditation_for_Analyses_of_Foods:_Considerations_for_Labs_and_Informatics_Vendors |title=FDA Food Safety Modernization Act Final Rule on Laboratory Accreditation for Analyses of Foods: Considerations for Labs and Informatics Vendors |author=Douglas, S. |work=LIMSwiki.org |date=21 February 2022 |accessdate=07 December 2022}}</ref> LAAF represents one of several legal and regulatory forces driving accreditation of food and beverage laboratories to a higher standard. It also means greater potential for more testing opportunities for the third-party food and beverage lab wishing to expand into enforcement and security roles. Similarly, the previously mentioned CPSC accredits labs to perform the specific testing required by children's product safety rules.<ref>{{Cite web |last=U.S. Consumer Product Safety Commission |title=Third-Party Testing Laboratory Accreditation & Small Entity Compliance Guide |url=https://www.cpsc.gov/Business--Manufacturing/Testing-Certification/Lab-Accreditation |date=2023 |accessdate=20 April 2023}}</ref> Again, as with authenticity and adulteration testing, accreditation-led testing is typically conducted by third-party labs separate from the manufacturer; however, this type of testing is a step above non-accredited labs and their methods, which may be required by certain manufacturers.
