A batch, as defined by the United States Environmental Protection Agency via its SEDD Specification Version 5.2, is "the primary mechanism for associating quality control samples with regular ones." The EPA notes that "analytical data review requires this association to assess the impact of quality control sample performance to the quality of the regular sample results."[1] In common laboratory practice, however, a batch may also simply be a grouping of two or more associated samples.[2]
