The OSAC Registry is a repository of high-quality, technically sound published and proposed standards for forensic science. These written documents define minimum requirements, best practices, standard protocols, and other guidance to help ensure that the results of forensic analyses are reliable and reproducible.

### New Standard Added to the OSAC Registry

#### SDO Published Standard (added October 5, 2021)

                  - *ASTM E3260-21  Standard Guide for Forensic Examination and Comparison of Pressure Sensitive Tapes . 

###### *CRIMINAL JUSTICE AGENCIES CAN ACCESS THE ASTM STANDARD LISTED ABOVE BY VISITING OSAC'S ACCESS TO STANDARDS WEBPAGE.

###### note: iso/IEC 17025:2005 General requirements for the competence of testing and calibration laboratories has been moved to the OSAC registry archive. 

To date, the OSAC Registry contains 72 standards (64 SDO published and 8 OSAC Proposed Standards), representing over 15 forensic science disciplines.

Visit the OSAC Registry webpage to see the complete list and access these standards.

Is your organization implementing standards on the OSAC Registry? Complete OSAC's Standards Implementation Declaration Form and send it to mark.stolorow [at] nist.gov (mark[dot]stolorow[at]nist[dot]gov) to let us know.

## Other News

### Input Needed from Glass Experts

The Glass Task Group of OSAC’s Trace Materials Subcommittee has created a survey that is intended to help them prioritize and improve the drafting and editing of ASTM standards related to forensic glass analysis. They are requesting your input so that they can better understand the current and anticipated future status of glass analysis at forensic laboratories.

The task group requests that only one survey be completed per laboratory, so please collaborate as needed to provide the most accurate answers for your laboratory. Please feel free to share the survey link with other laboratories that conduct trace evidence examinations, particularly those that conduct glass analysis.

**Survey link:**https://docs.google.com/forms/d/e/1FAIpQLSeQ6MV9XYvJuCqW9WBGCNdXziQBrWktb8S2ilJ5BtwnW24Q4A/viewform

The deadline to complete the survey is **October 19, 2021**. Please contact Troy Ernst (ernstt [at] michigan.gov (ernstt[at]michigan[dot]gov)) with any questions.
