The Materials (Trace) Subcommittee focuses on standards and guidelines related to examination and interpretation of physical evidence that may result from the transfer of small or minute quantities of materials (e.g., hairs, fibers, paint, tape, glass).

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.
In general, the development of standards and guidelines is transitioning from the Scientific Working Groups (SWGs) to the OSAC. Some SWGs will continue to operate to provide other resources within their discipline. The existing SWG documents will remain in effect until updated documents are disseminated by the OSAC or the SWG. SWGDAM will retain the responsibility for updating the FBI DNA Quality Assurance Standards.
