## The Organization of Scientific Area Committees for Forensic Science

#   OSAC Standards Bulletin

##     January 2020  

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).

                      - OSAC Registry Updates

## Bulletin Summary 

The OSAC Standards Bulletin is organized to capture the following standard development phases in the OSAC Registry Approval and SDO processes:
                  - After being published by an SDO, selected standards and guidelines may proceed to the OSAC Registry Approval Process where they are evaluated further for technical merit and impact on the forensic science community.
                  - In the SDO process, OSAC committees or task groups submit an idea (i.e., work item), a partially drafted document, or a fully drafted document to an SDO for further development, commenting, and publishing. 

**Number of New Standards Placed on the OSAC Registry:**None

**Number of OSAC Registry Documents Open for Comment:** None

**Number of SDO Documents Open for Comment:** Six (6)

## OSAC Registry Updates

The OSAC Registry serves as a trusted repository of high-quality, science-based standards and guidelines for forensic science practice. 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 a document’s high quality and to encourage its adoption by relevant stakeholders in the forensic science community.

### Standards Moving through the OSAC Registry Approval Process

The following standards have moved from one step in the OSAC Registry Approval process to another during the last month:

#### **In the Comment Adjudication Phase:**

                  - *ANSI/ASB Standard 020, Standard for Validation Studies of DNA Mixtures, and Development and Verification of a Laboratory’s Mixture Interpretation Protocol, First Edition, 2018* . 
                  - *ANSI/ASB Standard 040, Standard for Forensic DNA Interpretation and Comparison Protocols, First Edition, 2019* . 
                  - *ANSI/ASB Technical Report 097, Terminology Used for Forensic Footwear and Tire Evidence, First Edition, 2019* . 

For a list of all standards currently under consideration, please visit the OSAC website.  

If your organization is on the "tip of the spear" and has already embraced the OSAC Registry implementation efforts, let us know!

Please email mark.stolorow [at] nist.gov (mark[dot]stolorow[at]nist[dot]gov) to share your experience. 

## SDO Updates

### New or Revised Standards

Credit:

                  - On December 16, 2019 the American Academy of Forensic Science Standards Board (ASB) published  *ANSI/ASB Standard 030, Standard for a Quality Assurance Program in Bloodstain Pattern Analysis, First Edition, 2019* . This document, initially developed by  OSAC’s Bloodstain Pattern Analysis Subcommittee  and finalized by the ASB Bloodstain Pattern Analysis Consensus Body,provides requirements for establishing and maintaining a documented quality assurance program in bloodstain pattern analysis to forensic service providers.
                  - On December 16, 2019 ASB published  *ANSI/ASB Standard 044, Standard for the Examination of Documents for Indentations, First Edition, 2019* . This document was initially developed by SWGDOC, updated by  OSAC’s Forensic Document Examination Subcommittee , and finalized by the ASB Forensic Document Examination Consensus Body. It summarizes commonly accepted techniques, technologies, and procedures used by forensic document examiners for the examination of documents for indentations.
                  - On December 16, 2019 ASB published  *ANSI/ASB Standard 090, Standard for Sex Estimation in Forensic Anthropology, First Edition, 2019* . This document was initially developed by SWGANTH, updated by  OSAC’s Anthropology Subcommittee , and finalized by the ASB Anthropology Consensus Body. It describes methods for estimating sex from adult skeletal elements obtained directly from skeletal remains or radiographic images of skeletal remains. The methods in this standard provide a morphologically-based or mathematically-based scientific manner for estimating sex, and for documenting the sex estimation process. This document does not include sex estimation in skeletal elements from subadults, or through DNA analysis.

### Comment Period Open on Draft Documents

Consider sharing your expertise by commenting on the following documents to ensure they are technically sound and aligned with the needs of the forensic science community:

#### ASB:

                  - ASB 126, Best Practice Recommendation for Casting of Footwear and Tire Impression Evidence.  This new document provides best practice recommendations for casting of footwear and tire impression evidence by appropriate personnel. Following the recommendations described in this document should result in the optimal recovery of impressions.  Comment deadline January 13, 2020.  
                  - *ASB Technical Report 051, Scope of Work for a Footwear/Tire Examiner* . This technical report covers the primary responsibilities, types of examinations, and constituent duties of a footwear/tire examiner for lab management, quality assurance, law enforcement and the judiciary.  Comment deadline January 20, 2020.
                  - *ASB 114, Best Practice Recommendation for Validation of Forensic DNA Software* . This document assists a laboratory in designing validation studies to evaluate the various software programs used in the forensic DNA laboratory. Specifically, this guidance document applies to, but is not limited to the following: (a) software used as a component, part, or accessory of instrumentation; (b) software that impacts chain of custody documentation; (c) software that impacts the decision process and/or influences conclusions or reporting; and (d) software created by the laboratory to assist with calculations and/or data transfers.
