Certificate of analysis

A document that provides a defined set of information about a material's compliance with standards. The Certificate of Analysis, commonly called a COA, provides information such as material description, date the material was released and by whom (using electronic signature), intended use, material reference code, batch number, name and address of certifying body, result value, and so on. It is normally printed when all samples and tests in a batch have been completed and authorized or when disposed (whole batch dispositioned).
