## OSAC Registry Updates

The OSAC Registry serves as a repository of scientifically sound forensic science standards that address discipline-specific forensic science needs. 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 the document’s high quality and to encourage its use by relevant stakeholders in the forensic science community.

                  - ASB Best Practice Recommendation 052, *Best Practice Recommendation for the Detection of Footwear and Tire Impression Evidence* . This document provides best practice recommendations for personnel responsible for detecting footwear and tire impressions. These recommendations optimize the detection of impressions. The methods included in this document may not cover all aspects of unusual or uncommon conditions. This document is not intended as a substitute for training in the detecting of footwear and tire impression evidence. Completion of a training program and experience in these skills are essential to understanding and applying the recommendations outlined in this document.  Comment Deadline July 13, 2020.
                  - ASB Best Practice Recommendation 094, *Postmortem Impression Recovery: Guidance and Best Practices for Disaster Victim Identification* .

## Work Proposals for New or Revised Standards

The following documents are being initiated and are expected to result in a new or revised standard:

### ASB:

                  -  On May 29, 2020 a Project Initiation Notification System (PINS) was published on page 24 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 documents:                      -  BSR/ASB BPR 142-202x, *Best Practice Recommendations for the Resolution of Conflicts of Friction Ridge Examination*. 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. 
                    -  BSR/ASB BPR 146-202x, *Standard for Resolving Commingled Remains in Forensic Anthropology*. This standard provides the procedures and requirements for resolving commingled remains. The techniques presented include size, age, and sex similarities; articulation between 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.
                  -  On June 5, 2020 a PINS was published on page 23 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 Std 153-202x, *Standard Practices for Proficiency Testing for Forensic Toxicology Laboratories*. This document defines the minimum scope and frequency for proficiency testing for laboratories engaged in the following sub-disciplines: postmortem forensic toxicology, human performance toxicology (e.g., drug-facilitated crimes, driving-under-the-influence of alcohol or drugs, breath alcohol), and general forensic toxicology (non-lethal poisonings or intoxications). This document is not intended to cover employment drug testing or court-ordered toxicology (e.g., probation and parole, drug courts, child services).
                  -  On June 12, 2020 a PINS was published on page 31 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 Std 152-202x, Standard for Minimum Content Requirements of Forensic Toxicology Procedures. This document provides requirements for the minimum content of technical and analytical procedures in forensic toxicology. This standard applies to laboratories performing forensic toxicological analysis in the following subdisciplines: postmortem forensic toxicology; human performance toxicology (e.g., drug-facilitated crimes and driving-under-the-influence of alcohol or drugs); non-regulated employment drug testing, court-ordered toxicology (e.g., probation and parole, drug courts, child services, breath alcohol); and general forensic toxicology (non-lethal poisonings or intoxications).
                  -  On June 26, 2020 a PINS was published on page 86 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 documents:                      -  BSR/ASB Std 148-202x, *Standard for Personal Identification in Forensic Anthropology*. This standard provides requirements for establishing the biological profile and contributing information (such as comparative radiography and serial numbers on surgical implants) leading to a positive identification of human remains. This standard does not address identification of living individuals. 
                    -  BSR/ASB Std 149-202x, *Standard for Taphonomic Observations in Support of the Postmortem Interval*. This standard provides requirements for describing and analyzing the taphonomic effects on human remains and associated evidence that can be observed in the laboratory as well as in the field. Also, it provides requirements for recording and reporting the taphonomic and contextual indicators that contribute to estimating the postmortem interval in sufficient detail to allow for independent interpretation, replication, and verification of conclusions drawn. 
                    -  BSR/ASB Std 150-202x, *Standard for Determination of Medicolegal Significance from Skeletal Material*. This standard sets procedures required for the determination and identification of remains as skeletal or nonskeletal. It further sets methodological, testing, and observational procedures for identifying skeletal remains as either human or non-human and sets required procedures to assess the relevancy of human remains to the medicolegal death investigation system.

## NIST Invites Forensic Laboratories to Participate in the Cannabis Quality Assurance Program

Does your laboratory develop quantitative methods to distinguish hemp from marijuana? Then participate in NIST’s Cannabis Quality Assurance Program (CannaQAP). CannaQAP aims to help laboratories demonstrate and improve measurement comparability and/or competence for hemp determination through a perpetual interlaboratory study mechanism. Participating forensic laboratories can utilize this trusted tool to: 1) Obtain reliable quality control samples to evaluate an individual laboratory’s performance and provide data that can be used in the validation of its measurement capabilities or, 2) Use their results to demonstrate their laboratory’s purported capabilities. 

CannaQAP exercises are designed to include a variety of sample types in increasing order of complexity. Laboratories are highly encouraged to participate in all exercises. Exercise 1 was designed to assess sources of instrumental method variability and exercise 2 will introduce variability of sample preparation/extraction of plant materials. The CannaQAP schedule will include multiple Cannabis-derived oils and plant exercises.

NIST is also planning to release a hemp plant Reference Material with a tentative target date of July 2021. 

To participate in the CannaQAP, please contact the Cannabis/CannaQAP Team at cannabis [at] nist.gov (cannabis[at]nist[dot]gov). If you have any suggestions or questions regarding CannaQAP or other Cannabis projects at NIST, you can also email the Cannabis/CannaQAP Team.
