Ignitable Liquids, Explosives, & Gunshot Residue Subcommittee

OSAC Ignitable Liquids, Explosives & GSR SC icon only

 

The Ignitable Liquids, Explosives, & Gunshot Residue Subcommittee focuses on standards and guidelines related to the scientific examination and analysis of materials associated with fire and explosion investigations and the analysis of evidence that results from the deposition of or physical transfer of small or minute quantities of gunshot residue.

Discipline-Specific Baseline Documents

The Forensic Science Standards Board (FSSB) has provided the opportunity for OSAC subcommittees to identify baseline documents and reference materials that best reflect the current state of the practice within their respective disciplines. 

These documents contain practical information regarding these disciplines that can help forensic scientists, judges, lawyers, researchers, other interested parties and the general public, to better understand the nature, scope, and foundations of the individual disciplines as they are currently practiced.

It is important to note that the identification of these documents in this venue does not represent an endorsement by OSAC or NIST. Only documents that are posted on the OSAC Registry constitute OSAC endorsement. All copyrights for these documents are reserved by their owners. Subcommittee position statements or responses to data collections by the subcommittee represent the consensus opinion of the subcommittee, not necessarily the position of the entire OSAC organization or NIST.
