Since 2013, NIST has partnered with the U.S. Department of Justice to establish improved, more scientifically rigorous methods for collecting, analyzing, and reporting on forensic evidence. As part of this process, NIST Director Willie May co-chairs the National Commission on Forensic Science, and the NIST Special Programs Office serves as the administrator for the Organization of Scientific Area Committees (OSAC). Established in the last two years by NIST, these committees include more than 600 volunteer members from theforensic science community.
On Jan. 11, 2016, the OSAC Forensic Science Standards Board (FSSB) voted to elevate ASTM Standard E2329-14 "Standard Practice for Identification of Seized Drugs" to the OSAC Registry of Approved Standards. The standard is used by law enforcement agencies as a protocol for testing seized evidence to determine if drugs of abuse such as cocaine or heroin are present. The standard describes a qualitative, pass/fail process whereby evidence either does or does not contain specific substances. This is the first standard posted to the registry.
At the same time, concerns have been raised that some of the language in the standard is not scientifically rigorous. Both NIST and the FSSB have independently asked that ASTM review the language. For example, the standard currently states that "an appropriate analytical scheme effectively results in no uncertainty in reported identifications." NIST recognizes that the scientific community is still working to develop language that completely captures the confidence that should be associated with a qualitative measurement. Nevertheless, based on accepted scientific protocols, no measurement, qualitative or quantitative, should be characterized as without the risk of error or uncertainty. It is important to note that NIST is not contesting results obtained from seized evidence using the standard.
To respond to NIST's concerns, ASTM has listed the standard as "Under Revision," a process likely to take several months. To date, the OSAC has continued to include the standard on its registry. NIST hopes to assist ASTM in strengthening the technical merit of the standard over the coming months. In the meantime, NIST will work with the FSSB and all OSAC groups on process improvements to help ensure consistently high quality scientific reviews of documentary standards that the forensic science community can endorse as trusted, valuable resources.
NIST has posted an announcement regarding this position.

Upcoming Public Comment Periods for Standards/Guidelines under Consideration for the OSAC Registry
Status of Other Standards and Guidelines Recommended for Inclusion on the OSAC Registries
The aim of the Organization of Scientific Area Committees for Forensic Science (OSAC) is to identify and promote technically sound, consensus-based, fit-for-purpose documentary standards that are based on sound scientific principles. This will be achieved through the OSAC Registry of Approved Standards and the OSAC Registry of Approved Guidelines. A standard or guideline that is posted on either Registry demonstrates that the methods it contains have been assessed to be valid by forensic practitioners, academic researchers, measurement scientists, and statisticians through a consensus development process that allows participation and comment from all relevant stakeholders.
Below is a listing of standards or guidelines that are under consideration for the OSAC Registries, along with their status in the approval process.
Standards and Guidelines Open for Public Comment
The Forensic Document Examination Subcommittee has submitted the following standards for consideration to the OSAC Registry of Approved Standards. The public comment period is open on the Kavi Public Workspace under "documents".
The intent of the public comment period is to collect public opinion on inclusion of the standard to the OSAC Registry (OSAC is not soliciting potential revisions to the documents themselves.) The following standards are open for public comment:
ASTM: E2388-11 Standard Guide for Minimum Training Requirements for Forensic Document Examiners (for consideration as an OSAC standard)
This guide provides minimum requirements and procedures that should be used for the fundamental training of forensic document examiners. This guide may not cover all aspects of training for the topics addressed or for unusual or uncommon examinations.
Standards and Guidelines in Public Comment Adjudication Phase
Public comment period is closed for the following standards/guidelines as OSAC units review and adjudicate comments received.
ASTM: E2881-13e1 Standard Test Method for Extraction and Derivatization of Vegetable Oils and Fats from Fire Debris and Liquid Samples with Analysis by Gas Chromatography-Mass Spectrometry (for consideration as an OSAC Standard)
This test method covers the extraction, derivatization, and identification of fatty acids indicative of vegetable oils and fats in fire debris and liquid samples. This procedure will also extract animal oils and fats, as these are similar in chemical composition to vegetable oils and fats. Herein, the phrase "oils and fats" will be used to refer to both animal and vegetable derived oils and fats. This test method is suitable for successfully extracting oil and fat residues having 8 to 24 carbon atoms.
ASTM: E2916-13 Standard Terminology for Digital and Multimedia Evidence Examination (for consideration as an OSAC Guideline)
This document provides standard terminology for the subcommittees of Digital Evidence, Facial Identification, and Video Imaging Technology and Analysis.
ASTM: E2825-12 Standard Guide for Forensic Digital Image Processing (for consideration as an OSAC Standard)
This document provides digital image processing guidelines to ensure the production of quality forensic imagery for use as evidence in a court of law. It briefly describes advantages, disadvantages, and potential limitations of each major digital imaging process.
ASTM: E1610-14 Standard Guide for Forensic Paint Analysis and Comparison (for consideration as an OSAC Guideline)
This guide is designed to assist the forensic paint examiner in selecting and organizing an analytical scheme for identifying and comparing paints and coatings. The size and condition of the sample(s) will influence the selected analytical scheme.
ASTM: E2937-13 Standard Guide for Using Infrared Spectroscopy in Forensic Paint Examinations (for consideration as an OSAC Guideline)
This guide applies to the forensic IR analysis of paints and coatings and is intended to supplement information presented in the Forensic Paint Analysis and Comparison Guidelines (1)2 written by Scientific Working Group on Materials Analysis (SWGMAT). This guideline is limited to the discussion of Fourier Transform Infrared (FTIR) instruments and provides information on FTIR instrument setup, performance assessment, sample preparation, analysis and data interpretation.
Standards and Guidelines at FSSB for Vote
ASTM: E2330-12 Standard Test Method for Determination of Concentrations of Elements in Glass Samples Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for Forensic Comparisons (for consideration as an OSAC Standard)
One objective of a forensic glass examination is to compare glass samples to determine if they can be discriminated using their physical, optical or chemical properties (for example, color, refractive index (RI), density, elemental composition). If the samples are distinguishable in any of these observed and measured properties, it may be concluded that they did not originate from the same source of broken glass. If the samples are indistinguishable in all of these observed and measured properties, the possibility that they originated from the same source of glass cannot be eliminated. The use of an elemental analysis method such as inductively coupled plasma mass spectrometry yields high discrimination among sources of glass. This test method covers a procedure for quantitative determination of the concentrations of magnesium (Mg), aluminum (Al), iron (Fe), titanium (Ti), manganese (Mn), rubidium (Rb), strontium (Sr), zirconium (Zr), barium (Ba), lanthanum (La), cerium (Ce), neodymium (Nd), samarium (Sm), and lead (Pb) in glass samples.
ASTM: E2548-11e1 Standard Guide for Sampling Seized Drugs for Qualitative and Quantitative Analysis (for consideration as an OSAC Standard)
This guide covers minimum considerations for sampling of seized drugs for qualitative and quantitative analysis.
ASTM: E2926-13 Standard Test Method for Forensic Comparison of Glass Using Micro X-ray Fluorescence (μ-XRF) Spectrometry (for consideration as an OSAC Standard)
This test method is for the determination of major, minor, and trace elements present in glass fragments. The elemental composition of a glass fragment can be measured through the use of μ-XRF analysis for comparisons of glass. This test method covers the application of μ-XRF using mono- and poly- capillary optics, and an energy dispersive X-ray detector (EDS).
Standards and Guidelines in the Appeals Phase
The public appeals phase is open for the following standard. Appeals may only be submitted by individuals or groups that submitted a comment during the open public comment phase that believe their comment was not properly adjudicated. Submitted appeals must relate to the comment adjudication process, not technical issues.
No items are currently in the public appeals phase.
Research & Development Needs
A research need was identified by the Biological Methods Subcommittee in the Biology/DNA SAC. This research need is "To Improve the Analysis of Serological Evidence: ID of Body Fluid." Considerable research has been conducted to improve DNA analysis techniques but little has changed for the front end, the classical serological analysis of evidence. Research is underway to make improvements but the emphasis of the NIJ research portfolio should address the need to make real transformational change to how evidence is examined.It would be beneficial to add methods which would decrease the serological analysis time on items like sheets, clothing, etc.
Research needs can be found on the NIST OSAC Research Needs Assessments page.
Message from the OSAC Affairs Director: Report on 2016 Public Status Reports & Open Discussions
OSAC Scientific Area Committees held Public Status Reports & Open Discussions sessions at the the American Academy of Forensic Sciences (AAFS) in Las Vegas, NV on February 22-23, 2016. At the public meeting, OSAC units (5 Scientific Area Committee chairs and 25 Subcommittee Chairs) presented their unit's progress to the public, and solicited open discussion on topics presented.
Presentations opened with the Digital/Multimedia Scientific Area Committee (SAC). Dr. Richard Vorder Bruegge, SAC chair, emphasized that the reason the OSAC is in existence is "to strengthen forensic science by developing consensus-based standards and guidelines that are based on validated science and best practice." The OSAC has the support of more than 500 members with expertise as practitioners, quality assurance professionals, legal professionals, statisticians, and academics who are on board to achieve this goal.
"As science advances, our standards will change." – Richard Vorder Bruegge, Ph.D.
Speakers presented on their unit's progress on specific standards and guidelines, the identification of research & development needs, and also offered insight to their OSAC unit's experiences and discussions. Common themes, goals, and insights that were reported include the initial frustration that many subcommittees experienced when the majority of the documents that they submitted for consideration to the OSAC registry were rejected by a higher OSAC unit (the SAC). Rejection reasons were due to insufficient technical merit, lack of balance in the development process, or other issues. But these units can now acknowledge that at times this "rejection" is in fact a critical part of the OSAC process, and they are now recalibrating to focus on adding the validated science that some of these documents need. Other common themes expressed by speakers include the need to consider the influence of bias on stated opinions and conclusions, the consideration of the emotional toll that examiners face across disciplines, as well as the importance of standardized reporting processes.
Digital/Multimedia SAC and Subcommittee Presenters
Within the Digital/Multimedia SAC, four subcommittee chairs or their designees presented to include Digital Evidence led by James Darnell, Facial Identification led by Lora Sims, Speaker Recognition led by Hirotaka Nakasone (but briefed by Joseph Campbell), and Video/Imaging Technology & Analysis led by Carl Kriigel.

Recent OSAC Accomplishments
- The Forensic Science Standards Board (FSSB) added a Crime Scene Subcommittee under the Crime Scene/Death Investigation SAC to focus specifically on standards and guidelines related to the investigation of crime scenes including the search for, documentation of, collection of, and preservation of evidence associated with a crime scene.
- ASTM: E2329-14 Standard Practice for Identification of Seized Drugs was recently voted onto to the OSAC Registry of Approved Standards. Recently, ASTM announced that this standard is currently under revision in ASTM International to in order to address critical feedback related to the standards that arose through the OSAC process.
- OSAC units recently refined their focus to concentrate on 144 specific projects (standards/guidelines) moving within the OSAC processes. (Standards/guidelines projects were narrowed down from the original 360+ projects originally identified by the OSAC in February 2015, in order to strategically focus on each unit's priorities.)
- OSAC began to more widely use the following evaluation templates:
o Technical Merit Worksheet – a tool to evaluate the technical/scientific merit of a standard/guideline
o Harmonization Worksheet – a tool to evaluate how the standard/guideline interacts with other documents on the OSAC Registries
o Impact Worksheet – a tool to evaluate the impact the standard/guideline would have on laboratory operations if the document is implemented
o Standards Development Process Worksheet – a tool to evaluate the process used to generate a document if not developed through a recognized standards developing organization (SDO).
- OSAC launched a Research and Development Priorities webpage where research and development needs identified by subcommittees can be shared with the public, including funding agencies that support forensic science research.
- Distribution of NIST Forensic Science communications to include the OSAC newsletter recently increased to over 9,500 subscribers. The OSAC newsletter announces public comment periods, vacancies, future meetings and relevant standards news.
- OSAC launched two virtual interdisciplinary subcommittees that are considering specific cross-domain standards/issues which includes:
o Subcommittee #1: ISO/IEC 17025:2005 General Requirements for the Competence of Testing and Calibration Laboratories & ISO/IEC 17020:2012 Requirements for the Operation of Various Types of Bodies Performing Inspection
o Subcommittee #2: ANSI/NIST/ITL Data format for the Interchange of Fingerprint, Facial & Other Biometric Information
- OSAC launched two new critical task groups:
o Statisticians Task Group: statisticians from across OSAC are collaborating and can bring items from their OSAC unit to the task group for consideration and additional "feedback" or "weight".
o OSAC-wide Conclusions Task Group: members from relevant OSAC units discussing consistency of common terms related to conclusion statements in reports and testimony.
- OSAC executed several recent important events:
o January 25-29, 2016, Full OSAC Meeting with 600+ participants where OSAC units developed their priorities for the coming year.
o OSAC Public Status Meeting during AAFS on February 22-23, 2016, featuring 30 OSAC Unit presentations, over 392 online attendees and 100 on-site attendees participated. Archived webcasts & PDFs are available for public viewing.
o Implementation of standards included on the OSAC Registries is voluntary. One state laboratory system's drug chemistry section has started the implementation process by writing OSAC into their protocols:5.4.2 Selection of Methods: NOTE – The XX State Police Drug Chemistry section adheres to standards and guidelines from the Organization of Scientific Area Committees (OSAC) and recommendations by the Scientific Working Group for the Analysis of Seized Drugs (SWGDRUG) in formulating its testing methods and policies.
o NIST OSAC has entered into a contract with ASTM International to allow approximately 30,000 public criminal justice agencies free access to the ASTM Committee E30 on Forensic Science's standards.

THE PROSECUTOR'S DISCLOSURE OBLIGATIONS: OSAC-Legal Resource Committee (LRC)
This document provides a brief summary of the disclosure obligations of prosecutors in criminal cases, commonly referred to as the Brady obligation. For prosecutors to comply with the constitutional obligation recognized in Brady v. Maryland, 373 U.S. 83 (1963), their agents (including forensic service providers) must inform them about any and all information that might be subject to disclosure, as described below. Accordingly, forensic service providers should be familiar with the disclosure obligations Brady imposes on prosecutors, as well as additional discovery requirements imposed by state law.
ABA Model Rule of Professional Conduct, 3.8(d), adopted in whole or in part by the vast majority of jurisdictions, states the prosecutor shall "make timely disclosure to the defense of all evidence or information known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense, and, in connection with sentencing, disclose to the defense and to the tribunal all unprivileged mitigating information known to the prosecutor, except when the prosecutor is relieved of this responsibility by a protective order of the tribunal."
The prosecutor also has a constitutional obligation under Brady and later cases to disclose all information or evidence that is both "favorable" to the defense and "material" to the case, including but not limited to information in the possession of forensic science service providers."Favorable" information or evidence is that which would (1) tend to impeach a government witness or its theory of the case; or (2) is exculpatory regarding either the defendant's guilt, the degree of that guilt, or the potential sentence to be imposed."Material" evidence is that which, had it been disclosed to the defense, would have had sufficient impact on the case to undermine confidence in the outcome.
The fact that a prosecutor does not know about the existence of information that is "favorable" and "material" to the defense, including but not limited to information in the possession of forensic science service providers, does not impact his or her constitutional duty to disclose it.
Some jurisdictions have determined their version of Model Rule 3.8(d) imposes a duty on the prosecutor beyond that required under the Brady line of decisions. These jurisdictions hold Rule 3.8(d) requires a prosecutor to disclose any information or evidence known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense—this would include information held by forensic science service providers—even if that information is not necessarily "material" under Brady. Other jurisdictions have held their version of Model Rule 3.8(d) is co-extensive with the Brady line of cases in that it only requires the information or evidence be both "favorable" and "material" to the defense for a violation to have occurred.
In addition to providing information to prosecutors so they may comply with their disclosure obligations under Brady and related state law, forensic science service providers may have additional obligations to disclose information to oversight bodies and other stakeholders in the criminal justice system as well as to conduct retroactive case reviews after discovering a significant non-conformance. These obligations may be informed by a variety of sources including but not limited to: (1) the laboratory's accreditation standards and internal standard operating procedures; (2) applicable state law; (3) guidance provided by the National Commission on Forensic Science; (4) guidance provided by state oversight bodies or forensic science commissions; and (5) guidance provided by the Forensic Science Standards Board of the Organization for Scientific Area Committees.

OSAC Unit Spotlight: Focus on Four Subcommittees within the Chemistry/Instrumental SAC
By Robyn Weimer
As reported in last month's newsletter, over 500 OSAC members braved the snow and gathered in Virginia for the recent January 2016 meeting. Notable unit activities from that meeting and other recent efforts include:
The interpretation task group has made significant progress in drafting a document addressing how to interpret and describe the significance of the overall results of a comparative examination. The outreach task group is intended to identify the needs and perception of the TE community and determine opportunities to promote TE. This task group was responsible for the recent surveys distributed to lab managers and to trace evidence examiners (that was also included in a recent OSAC newsletter). Much appreciation and thanks go out to the over 300 examiners who responded! Survey results will help this task group strategize how to best target education initiatives, promotion of trace evidence, research needs, and areas for improvement. They plan to compile the survey results into a JASTEE article later this year. Another survey is currently in revision for distribution to lawyers. The Outreach task group has concurrently been working on a field guide for Trace Evidence targeting crime scene personnel. As part of their initiatives, they also ask examiners to start gathering any adjudicated cases where trace evidence was critical to the case. They intend to compile these cases to help show the value of trace evidence and provide as a reference. If you have such a case, please forward the case information to Sandy Parent, firstname.lastname@example.org.
An eighth task group was created over the summer to determine research gaps within the Trace Evidence field. The group developed a list of research needs and will continue to do so. Of those ideas, two were put forth to the subcommittee at the latest meeting and approved for posting to the OSAC website. In time, more are expected to be added.
One of the main topics discussed by the subcommittee in the recent OSAC meeting was the, soon to be released, revised ASTM E1588 GSR by SEM/EDS standard which has been changed from an ASTM "Standard Guide" to a "Standard Practice". Once this document has been through the ASTM vetting process, it will then be sent through the OSAC approval process.
Many of last year's initiatives (such as Terminology and Resources/References task group efforts) are large undertakings that will continue into 2016, some in coordination with other Subcommittees. As with other subcommittees, a research initiatives task group has been formed since the 2015 meeting. A number of research and development needs have since been identified with hopes that they will soon be posted on the OSAC website. In 2016, this subcommittee will focus on two significant areas. The first is conducting one or more workshops to test the currently drafted guide on the field collection of soil samples. ASTEE members will be notified once such a workshop has been scheduled. The second area of focus is the drafting of a new guide for the forensic examination of soil evidence. This will hopefully be the backbone upon which several soil analysis-related standards and guides are built.
