## SDO Updates

### Documents Recently Published by an SDO

The following three documents have recently been published by an SDO:
                  - ANSI/ASB Standard 093, *Standard Test Method for the Examination and Testing of Firearms*, First Edition, 2020 . This document, initially drafted by OSAC’s Firearms & Toolmarks Subcommittee and finalized by the ASB Firearms and Toolmarks Consensus Body, establishes standard procedures for the examination and testing of a firearm by firearm and toolmark examiners or technicians. Following these procedures, an examiner or technician will be able to conduct, document, and report the examination and testing of a firearm.

This document, initially drafted by OSAC’s Footwear & Tire Subcommittee and finalized by the ASB Footwear and Tire Consensus Body, provides best practice recommendations for casting of footwear and tire impression evidence by appropriate personnel. 
                  - ISO 20888:2020 – *Vocabulary and designation system for forensic oro-dental data* . 

### SDO Documents Open for Comment

#### ASB:

                  -  ASB Standard 132, *Standard for Population Affinity in Estimation in Forensic Anthropology*. This standard provides procedures for the estimation of population affinity from skeletal material. Specific methods and techniques are not included. This standard is not applicable to subadult skeletal remains, when cranial and postcranial features are not fully developed. **Comment deadline December 7, 2020.** 
                  -  ASB Standard 127, *Standard for the Preservation and Examination of Charred Documents*. This document establishes the minimum required procedures used by Forensic Document Examiners (FDEs) in the preservation of, examination of, and reporting on charred documents. This generally includes the examination of charred documents for content (writing, printing), material (paper, cardboard, plastic etc.) and source determination. This does not include chemical examination of documents for accelerants or source of combustion. **Comment deadline December 14, 2020.** 
                  -  ASB Standard 128, *Standard for the Preservation and Examination of Liquid Soaked Documents*. This document establishes the minimum required procedures used by FDEs in the preservation of, examination of, and reporting on liquid-soaked documents. This generally includes the examination of documents exposed to liquids (water, blood, oils etc.) for content (writing, printing), material (paper, cardboard, plastic etc.), and source determination. This standard does not include the examination of documents for the identification of the liquid contaminate(s). **Comment deadline December 14, 2020.** 
                  -  Recirculation* – ASB Standard 061, *Firearms and Toolmarks 3D Measurement Systems and Measurement Quality Control*. This document provides requirements for the measurements systems (the instruments and included scan acquisition software) which capture data beyond a flat 2D photographic image for Firearm and Toolmark Analysis (these systems are referred to as 3D systems in this document). This standard provides requirements to ensure the instrument’s accuracy, to conduct instrument calibration, and to estimate measurement uncertainty for each axis (X, Y, and Z). Included in the standard are procedures for validation of 3D system hardware. The focus of this standard is on the hardware and resulting measurement data and does not include the requirements for measurement systems software. **Comment deadline January 14, 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] aafs.org (asb[at]aafs[dot]org) by the comment deadline.
