The Organization of Scientific Area Committees (OSAC) for Forensic Science Standards Bulletin provides an update on forensic science standards that are moving through the Registry Approval Process at OSAC and those moving through the development process at standards developing organizations (SDOs).
The OSAC Standards Bulletin is organized to capture the following standard development phases in the OSAC Registry Approval and SDO processes:
The OSAC Registry serves as a repository of scientifically sound forensic science standards that address discipline-specific forensic science needs. A document included on the Registry has progressed through the formal SDO process and has been published as a standard. OSAC elevates standards to the OSAC Registry as an endorsement of the document’s high quality and to encourage its use by relevant stakeholders in the forensic science community.
OSAC has added the following standards to the Registry:
Please submit your comments by 11:59 p.m. ET on June 13, 2020 on whether the following standards should be included on the OSAC Registry.
For a list of all standards currently under consideration, please visit the OSAC website.
Has your organization already started implementing OSAC Registry Approved standards? Complete OSAC's Laboratory Implementation Declaration Form and send it to mark.stolorow [at] nist.gov to let us know. Share your implementation experience and be featured in a future OSAC news post.

For access to the ASTM documents listed above, contact Brian Milewski (bmilewski [at] astm.org) to become a member of Committee E30 on Forensic Science.
The following document is being initiated and is expected to result in a new or revised standard.
In preparation for submitting a document to ASTM for formal standards development, OSAC’s Materials (Trace) Subcommittee will be conducting an interlaboratory data collection exercise to evaluate the draft of its Standard Practice for Interpretation and Report Writing in Forensic Comparison of Trace Materials.
The focus of the first round of this study will be on forensic paint analysis. Please be on the lookout for an announcement regarding a web-based training session introducing participants to the draft document and exercise, which is expected to begin this summer. We encourage you to share this information with your colleagues and visit the Materials (Trace) Subcommittee webpage to start reviewing the document now, with particular attention to Sections 1-5 and 9.
If you have questions or would like to participate in the exercise, please contact Andria Mehltretter at ahmehltretter [at] fbi.gov.
ASB is forming a new Crime Scene Investigation Consensus Body. If you’re interested in participating, please apply by May 29, 2020 using the on-line application form. Members will be selected by the Board of Directors of the ASB. Please send any additional questions to tambrosius [at] aafs.org.
