The First OSAC-approved Standard for Forensic Science

"All results for every forensic science method should indicate the uncertainty in the measurements that are made, and studies must be conducted that enable the estimation of those values." Source: National Research Council Committee on Identifying the Needs of the Forensic Science Community, Strengthening Forensic Science in the United States: A Path Forward 184 (2009)

"It is expected that in the absence of unforeseen error, an appropriate analytical scheme effectively results in no uncertainty in reported identifications." Source: Standard Practice for Identification of Seized Drugs (ASTM E2329-14, § 4.2), added to the National Institute of Standards and Technology OSAC Registry of Approved Standards on Jan. 27, 2016

The response to comments from within OSAC on this and related text in the ASTM standard stated: "Editorial. The Seized Drug subcommittee intends to clarify the quoted language pertaining to uncertainty and error during the next ASTM revision of this document."
