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.

### Four New Standards Added to the OSAC Registry

#### SDO Published Standards

                  - ASTM E1968-19 *Standard Practice for Microcrystal Testing in Forensic Analysis for Cocaine*  (added July 6, 2021).
                  - ASTM E1969-19 *Standard Practice for Microcrystal Testing in Forensic Analysis for Methamphetamine and Amphetamine*  (added July 6, 2021).

Criminal justice agencies can access the ASTM standards listed above by visiting OSAC's Access to Standards webpage. 

### Standards Open for Comment

#### OSAC Registry Approval Process for OSAC Proposed Standards

The OSAC Registry approval process for OSAC Proposed Standards is used to review OSAC drafted standards for technical quality and placement on the Registry. The following OSAC draft proposed standards are being considered for submission to an SDO. The final draft provided to the SDO will be available on the OSAC Registry as an “OSAC Proposed Standard.” OSAC welcomes comments on whether the current draft is suitable for release to the SDO as well as suggestions for improvements in content and wording. **To be considered, comments must be placed in the OSAC Comment Form and sent to comments [at] nist.gov (comments[at]nist[dot]gov) by 11:59 p.m. ET on August 2, 2021.**
                  - OSAC 2020-S-0003, *Guidelines for Performing Alcohol Calculations in Forensic Toxicology* .	                     - OSAC 2020-S-0003 STRP Report  |  Subcommittee response to STRP report

## SDO Updates

### New SDO Published Standards

The following standard has recently been published by ASTM:
                  - ASTM E2225-21 *Standard Guide for Forensic Examination of Fabrics and Cordage* . This revised guide was drafted by OSAC’s Trace Evidence Subcommittee and finalized by ASTM Committee E30.01 and is intended to assist individuals and laboratories that conduct examinations of fabrics and cordage for the purposes of analyzing and comparing types of fabric, cordage, and damage. A complete characterization of the fabrics, including their construction and other materials used in the assemblage of a textile (for example, sewing thread), is a critical component of a comprehensive forensic fabric or cordage examination.

### OSAC Registry Implementation Survey: Your Input Needed

OSAC is seeking to understand how organizations are using standards on the OSAC Registry and what support they need to improve implementation. To do that, we have released a survey to assess the current state of Registry implementation. The survey is intended to be a yearly snapshot and assessment, and the first one will cover the 46 Registry standards posted through March 2021. 

**The survey will close August 20** and results will be shared in OSAC’s Fall Newsletter/Annual Report, later in October. If you have any questions, please email the OSAC Program Office at forensics [at] nist.gov (forensics[at]nist[dot]gov).
