### **Work Proposals for New or Revised Standards**

On August 11, 2023, a Project Initiation Notification System (PINS) was published on pages 2 and 5 in the *ANSI Standards Action*. This will begin ADA and ASTM’s work on the following standards:
                  - BSR/ADA Standard No. 1058-202x, Dentistry - Forensic Dental Data Set (national adoption of ISO 20888:2020 with modifications and revision of ANSI/ADA Standard No. 1058-2010 (R2020)). The purpose of this standard is to provide uniform nomenclature for the description of forensic dental data and define a standardized set of uniform terms to convey this information. This standard meets the requirement to support the goal of interoperability between dental systems or dental-medical systems. 
                  - BSR/ASTM E1020-202x,  *Standard Practice for Reporting Incidents that May Involve Criminal or Civil Litigation*  (new standard). This practice covers guidelines for the collection and preservation of information and physical evidence and the preparation of a documentation report relative to any incident(s) involving personal injury, property damage, commercial loss, or criminal acts which may reasonably be expected to be the subject of litigation.

On August 25, 2023, a Project Initiation Notification System (PINS) was published on pages 2-3 in the *ANSI Standards Action*. This will begin ASB’s work on the following standards:
                  - BSR/ASB BPR 122-202x,  *Best Practice Recommendation for Performing Alcohol Calculations in Forensic Toxicology*  (new standard). This document provides recommendations for performing alcohol (ethanol) calculations to include retrograde extrapolation, forward estimations, minimum drinks consumed, and other typical situations/scenarios. Recommendations are also provided for evaluation of post-absorptive stage, various specimen types, population variances, and reporting of calculations. The principles and practices outlined in this best practice recommendation may also apply to postmortem scenarios, but there are additional variables to be considered that are outside the scope of this document. Expert opinions based on the results of these calculations are outside the scope of this document.                      - This is currently on the OSAC Registry as OSAC 2020-S-0003,  *Guidelines for Performing Alcohol Calculations.*
                  - BSR/ASB Best Practice Recommendation 144 Addendum-202x,  *Addendum to Best Practice Recommendations for the Verification Component in Friction Ridge Examination*  (revision of ANSI/ASB BPR 144-2022). This document provides best practice recommendations for conducting the verification phase during friction ridge impression examinations. These recommendations apply to both suitability determinations and resulting conclusions addressing verification considerations (e.g., extent, utility, case type, approach), types of verification and application options, and documentation. This document does not address technical review.
                  - BSR/ASB Standard 173-202x,  *Standard for Education, Training, Continuing Education, and Certification of Forensic Toxicology Laboratory Personnel*  (new standard). This document provides minimum requirements for educational qualifications, training, competency, experience, continuing education, and certification of laboratory personnel performing, interpreting, or overseeing forensic toxicology analysis, as well as anyone performing breath alcohol instrument calibration. This applies to the following sub-disciplines: postmortem toxicology, human performance toxicology (e.g., drug-facilitated crimes and driving under-the-influence of alcohol or drugs), non-regulated employment drug testing, and other forensic testing (e.g., court-ordered toxicology, general forensic toxicology). The following are outside the scope of this document: laboratory personnel that exclusively perform administrative or non-technical duties; individuals working as breath alcohol instrument operators; individuals performing calibration adjustments to breath alcohol instruments, individuals who solely perform instrument maintenance activities, or individuals engaged in expert consultation outside of a forensic toxicology laboratory.                      - This was drafted by OSAC’s Forensic Toxicology Subcommittee as OSAC 2021-N-0026,  *Standard for Education and Training of Forensic Toxicology Personnel.*
                  - BSR/ASB Standard 187-202x,  *Standard for Use of Serological Testing Methods Associated with Forensic Investigations*  (new standard). This standard provides requirements for the quality assurance of documenting analytical procedures/protocols needed for the use of forensic serological methods to evaluate body fluids associated with forensic investigations. This standard includes requirements for laboratory facilities and evidence control; use and monitoring of the analytical procedures; reagents, chemicals, and equipment used for forensic serological testing. Also covered in this standard are the requirements for personnel performing serological testing, equipment maintenance/calibration, reports, records of testing, technical reviews, and administrative reviews. This document does not address details of validation, training, evidence handling, sample collection and preservation, reporting of analyses, testimony, and safety.                      - This is currently on the OSAC Registry as OSAC 2021-S-0028, *Standard for Use of Serological Testing Methods Associated with Forensic Investigations.*
                  - BSR/ASB Standard 201-202x,  *Standard for the Examination of Financial, Identification, and Other Authorized Documents*  (new standard). This standard provides procedures and requirements for determining the authenticity of financial (e.g., currency, checks, bonds), identification (e.g., driver licenses, passports), and other authorized documents (e.g., social security cards, vital records documents) that may originate with an issuing entity.
                  - BSR/ASB Standard 203-202x,  *Standard for the Development of a Bloodstain Pattern Analyst Certification Program*  (new standard). This document establishes the requirements for the development of a Bloodstain Pattern Analyst Certification program by certification providers.                      - This is currently on the OSAC Registry as OSAC 2022-N-0010,  *Standards for Development of an Accredited Bloodstain Pattern Analyst Certification Program* .
