Trace Materials Subcommittee

OSAC Trace Materials SC icon

The Trace Materials 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, geological materials).

Other Work Products

NEW:

  • Trace Evidence Collection App. The Outreach Task Group of the Trace Materials Subcommittee, in collaboration wiht NIST and the Forensic Technology Center of Excellence (FTCoE) have developed an app to assist crime scene teams and law enforcement officers with the recognition, collection, and preservation of trace evidence. Visit OSAC's Trace Evidence Collection App webpage and view this video to learn more. 

Interlaboratory Comparisons

  • In the summer of 2020, the Trace Materials SC conducted an interlaboratory data collection exercise to evaluate the draft of its Standard Practice for Interpretation and Report Writing in Forensic Comparisons of Trace Materials, with the first round of the study focusing on forensic paint analysis. The document is currently under revision (OSAC 2022-S-0029) and the draft used for the interlaboratory study is here
