## SDO Updates

## Published

On April 21, 2020 the American Academy of Forensic Science Standards Board (ASB) announced the publication of ANSI/ASB Standard 032, *Standards for a Bloodstain Pattern Analyst’s Training Program*, First Edition, 2020. This document, initially developed by OSAC’s Bloodstain Pattern Analysis Subcommittee and finalized by the ASB Bloodstain Pattern Analysis Consensus Body, provides minimum pre-training educational requirements for an individual currently in, or entering a bloodstain pattern analysis training program. It also describes the minimum training requirements that a trainee must successfully complete prior to practicing as a bloodstain pattern analyst.

## **New 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 15, 2020 a Project Initiation Notification System (PINS) was published on page 33 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 144-202x,  Best Practice Recommendations for the Verification Component in Friction Ridge Examination . This document provides best practice recommendations for how to conduct the verification phase during friction ridge impression examinations. These examinations apply to both suitability determinations and resulting conclusions addressing verification considerations (e.g., extent, utility, case type, approach), types of verification and applications options, and documentation. This document does not address technical review.
                    - BSR/ASB Std 147-202x,  Standard for Analyzing and Reporting on Skeletal Trauma in Forensic Anthropology . This standard provides requirements for documenting, describing, interpreting, and reporting skeletal trauma in forensic anthropology. It also provides requirements for the determination of trauma timing (i.e., antemortem, perimortem, or postmortem) and the identification of the mechanism that produced the trauma (i.e., high-velocity projectile, blunt force, sharp force, thermal). This document does not address cause and manner of death.

## Other News

### New Resource Available for the Seized Drugs Discipline: Gas Chromatography-Mass Spectrometry Analysis Considerations Document

The OSAC’s Seized Drugs Subcommittee has a new resource available for the forensic science community. The *Gas Chromatography-Mass Spectroscopy (GC/MS) Analysis Considerations* document aims to raise awareness of certain GC-MS analytical challenges and limitations that may occur during the analysis of specific substances in seized drug evidence. The document also includes references that explain limitations or considerations or demonstrate how to overcome these respective limitations or considerations. This document is available on the Seized Drugs Subcommittee website and will be updated regularly. Stakeholders are encouraged to submit additional information (e.g., compounds, analysis considerations, references, etc.) for consideration in future revisions.

### Help Evaluate OSAC’s Materials (Trace) Draft Document, Standard Practice for Interpretation and Report Writing in Forensic Comparison of Trace Materials

In preparation for submitting a document to ASTM for formal standards development, OSAC’s Materials (Trace) Subcommittee will be conducting an interlaboratory data collection exercise to evaluate the draft of its *Standard Practice for Interpretation and Report Writing in Forensic Comparison of Trace Materials*.

The focus of the first round of this study will be on forensic paint analysis. A web-based training session will be held **June 11, 2020 at 1:00 p.m. EDT** to introduce participants to the draft document and exercise. The time commitment for participants starts with this approximately one-hour training session and includes some additional preparation time for studying the guidance document and several hours within a selected one-week time period over the summer to complete the exercise. Participants will have 15 scenarios to work through and choose a conclusion. No data will be provided to view and evaluate; however, the summary of data and results will be shared.

The draft document can be found on the Materials (Trace) Subcommittee website in the Under Development section. We encourage you to start reviewing this document now, paying attention to sections 1-5 and 9 and to share this information with your colleagues. 

To participate, please complete this form. If you have any questions about this interlaboratory exercise, please send them to Andria Mehltretter (ahmehltretter [at] fbi.gov (ahmehltretter[at]fbi[dot]gov)). 

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

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, while also incorporating extracts, concentrates, distillates, and edibles in future 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.

### Funding Available for Standards Curricula Development

OSAC encourages stakeholders to apply to NIST’s FY2020 Standards Services Curricula Development Cooperative Agreement Program. This program awards funding to eligible applicants to develop undergraduate or graduate level curricula to incorporate documentary standards, standards development, and standardization information and content into seminars, modules, courses, and learning resources. **Applications must be submitted through grants.gov no later than 11:59 p.m. ET on June 15, 2020.**

### **2020 Call for Members for ASB Consensus Bodies**

The ASB is currently accepting applications for openings in their consensus bodies. Please visit the ASB website for more information on the different consensus bodies, interest categories, and how to apply. **Applications will be accepted until July 3, 2020**.
