OSAC Registry Updates

OSAC Registry Ribbon

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

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] (comments[at]nist[dot]gov) by 11:59 p.m. ET on August 2, 2021.

*OSAC Resource Task Group members are encouraged to review and submit comments on these documents to forensic [at] (forensics[at]nist[dot]gov) in accordance with the STRP process.

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.

Standards Open for Comment at SDOs

Academy Standards Board (ASB):

  • Recirculation* – ASB Standard 127, Standard for the Preservation and Examination of Charred Documents, First Edition, 2021.

This standard covers requirements for the selection, kenneling and health care pertaining to detection canines. It does not include training methodology standards. Comment deadline July 19, 2021. 
  • Recirculation* – ASB Standard 092, Standard for Training and Certification of Canine Detection of Explosives, First Edition, 2021. This standard provides the training requirements for a canine team (canine handler and canine), and details follow-on assessments for trained canine teams, in the field of explosives detection including traditional explosives detection canines (EDC), person screening canines (PSC), and explosives detection canines with person screening capabilities (EDC w/PSC). This standard is intended to be used as the basis for all phases of the training process and includes certification procedures, training and assessments, record keeping, and document management. Comment deadline July 19, 2021. 
  • Recirculation* – ASB Best Practice Recommendation 142, Best Practice Recommendations for the Resolution of Conflicts in Friction Ridge Examination, First Edition, 2021. This document provides the best practice recommendations for how to resolve conflicts between examiners at any point during the technical review or verification process of conflicting suitability decisions, conflicting source conclusions, and documentation of conflict resolution. This document does not address differences of opinion that occur at the consultation level or any organizational response once an error is discovered or the conflict(s) are resolved. Comment deadline July 19, 2021. 
  • Recirculation* – ASB Standard 146, Standard for Resolving Commingled Remains in Forensic Anthropology, First Edition, 2021. This document provides laboratory and field procedures and requirements for resolving commingled remains. The techniques presented include size, age, and sex similarities, articulation between skeletal elements, taphonomic similarities, and reconstruction of fragmentary remains. The document also describes the determination of MNI (Minimum Number of Individuals), as well as the LI (Lincoln Index) and MLNI (Most Likely Number of Individuals) based on the number of paired and unpaired bones. Comment deadline July 19, 2021. 
  • ASB Standard 138, Standard for Collection of Known DNA Samples from Domestic Mammals, First Edition, 2021. This standard provides the protocol for obtaining genetic known evidence samples (i.e., buccal swabs and pulled hair) for the purpose of genetic analysis from domestic animals such as dogs, cats, or livestock. This standard does not address sampling of non-domesticated animals. Comment deadline August 9, 2021.

*Comments on a re-circulation will only be accepted on revised sections of a document. Comments made to text not revised from the original comment period will not be accepted. 

For the ASB documents listed above, download the comment template and return it to asb [at] (asb[at]aafs[dot]org) by the comment deadline. 

Work Proposals for New or Revised Standards

The following documents are being initiated and are expected to result in new or revised standards.


  • On June 25, 2021, a Project Initiation Notification System (PINS) was published on page two in the ANSI Standards Action. This will begin a 30-day period for public comment on the initiation of ASB’s work on the following document:
    • BSR/ASB 172, Standard for Examination of Mechanical Checkwriters and their Impressions. This standard provides procedures for determining classification information and machine identification of mechanical checkwriters. These procedures include evaluation of the material. These procedures are applicable whether the examination and comparison is of questioned and known items or of exclusively questioned items.

OSAC Registry Implementation Survey: Your Input Needed

quote bubble and pencil

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] (forensics[at]nist[dot]gov).
