Message from the FSSB: Consolidating OSAC Registries by January 2017 | Article Contributed by Brad Wing From ToxTalk® | OSAC Vacancies | Status of Standards Documents Recommended for Inclusion on the OSAC Registries | Message from the OSAC Affairs Director | Recent OSAC Accomplishments | On the Horizon | Standards Developing Organization (SDO) News
The OSAC Registries are a trusted repository of high-quality, science-based standards and guidelines for forensic science. Since the program inception, the Organization of Scientific Area Committees (OSAC) for Forensic Science has operated with two registries, the OSAC Registry of Approved Standards as well as the OSAC Registry of Approved Guidelines.
However, since OSAC members and stakeholders reported confusion over the true difference between a “standard” versus “guideline,” the Forensic Science Standards Board (FSSB) has decided to consolidate the two lists into one, simply titled “OSAC Registry.” All approved documents, whether they are a standard, guideline, test method, or other product, will soon be contained on one registry.
The anticipated timeframe to fully transition to one registry is by January 2017, in order to allow OSAC time to first adjust program materials and processes.
Once consolidated, the three OSAC-approved documents: NFPA 921: National Fire Protection Association Guide for Fire and Explosion Investigations, ISO/IEC 17025 2005: General Requirements for the Competence of Testing and Calibration Laboratories, and ASTM E2329-14 Standard Practice for Identification of Seized Drugs, as well as any new documents that are approved, will be located in one place.

Why Do We Need an SDO If We Have OSAC?
SDO is a term meaning Standards Developing Organization. OSAC stands for the Organization of Scientific Area Committees. The AAFS has established an SDO (called the AAFS Standards Board, abbreviated ASB) that works closely with OSAC to develop voluntary consensus standards, technical reports and best practice recommendations.
OSAC is administered by the National Institute of Standards and Technology (NIST). OSAC publishes the Registry of Approved Standards and the Registry of Approved Guidelines for the forensics community. Each document listed in the registries is required to be based upon sound scientific principles and to have been developed in a consensus-based process. OSAC has 25 subcommittees, each focused upon a specific area of forensics. These subcommittees are responsible for determining which documents to submit to the Registries, but also to identify gaps and needs in standards and related documents. Another function of the subcommittees is to identify research needs and publicize these needs to Federal agencies.
The term voluntary consensus standards is the key as to why the ASB was created, and why OSAC needs the cooperation and participation of the ASB and other SDOs. In 1995, Congress passed a law called the National Technology Transfer and Advancement Act (NTTAA). This law states “All federal agencies must use voluntary consensus standards in lieu of government-unique standards in their procurement and regulatory activities, except where inconsistent with law or otherwise impractical.” This also has a trickledown effect, since Federal grants involving standards are also subject to NTTAA. The important point for this discussion is that OSAC was not created to generate voluntary consensus standards. The NTTAA and the policy document explaining it define the processes required to develop a voluntary consensus standard:
ii. Balance of interest
iii. Due process
iv. An appeals process
v. Consensus, which is defined as general agreement, but not necessarily unanimity and includes a process for attempting to resolve objections by interested parties…”
The AAFS Academy Standards Board (ASB) meets these criteria. In fact, it has been accredited by the American National Standards Institute (ANSI), which requires adherence to the principles defined above. OSAC is not an SDO and will not become an SDO. While an OSAC subcommittee may identify a gap in existing standards for a field, and even develop a draft document for submittal to an SDO, it is the role of the SDO to ensure that the procedures are properly followed so that the requirements of the NTTAA for voluntary consensus standards are met.
The ASB accomplishes this by forming consensus bodies (CBs). Currently there are 13 such CBs (Anthropology, Bloodstain Pattern Analysis, Disaster Victim Identification, DNA, Dogs and Sensors, Firearms and Toolmarks, Footwear and Tiretracks, Forensic Document Examination, Friction Ridge, Medicolegal Death Investigation, Patterned Injury, Toxicology, and Wildlife Forensics). With the exception of Patterned Injury, these exactly correspond to OSAC subcommittees. The CBs are made up of individuals from different backgrounds, which are characterized by ‘interest categories,’ of which we have eight: academia, consumer groups, general interest (typically lawyers and judges), laboratories and testing facilities, producers, subject matter experts, user/government and user/ industry. This helps to ensure balance of interest – one of the key requirements for an SDO.
Consensus bodies (which develop the standards) hold meetings open to all interested parties and are comprised of experts from the eight interest categories listed above. There is a defined process to develop the documents – ensuring due process, including an appeals procedure. Each document is put out for public review, so that any interested party—even if they do not participate on the consensus body—may comment on the document. The consensus body is responsible for adjudicating any issues that may arise during the review. Consensus must be reached among the members of the consensus body for a document to be adopted. In addition, the Board of the ASB must approve the document prior to submission to ANSI (which allows a standard to become an American National Standard).
This is all well and good, but it still doesn’t answer the question of why the AAFS now has an SDO.
When OSAC was established, it became apparent that some fields in forensic science had existing relationships with SDOs – such as in fire science and gunshot residue. Others may have had professional organizations (such as the American Board of Forensic Odontology) which had issued guidance documents. In some fields there were Scientific Working Groups (SWG), such as in DNA. However, the standards and best practice guidelines produced by professional organizations and SWGs do not meet the requirements of the NTTAA for being voluntary consensus standards. OSAC approached several professional groups, including AAFS to see if any were interested and capable of establishing an SDO to generate voluntary consensus standards.
The AAFS accepted the challenge and created the ASB. The ASB CBs have close relationships with their corresponding OSAC subcommittees but the CBs may also generate documents on their own. Some documents may be proposed directly by professional organizations, or even by individuals not associated with OSAC.
The CBs need assistance in determining the scientific underpinnings that must be included in ASB standards and best practice recommendations. CBs will typically reach out to OSAC subcommittees to provide the necessary scientific and operational foundation for the requirements in a standard or best practice recommendation.
Once a standard or best practice recommendation is finalized by the ASB, the corresponding OSAC subcommittee may refer it for inclusion in the appropriate Registry – thus completing the loop of interrelationship of OSAC subcommittees and ASB CBs.
The ASB Consensus Bodies are open to anyone with an interest in forensic science. Updates as well as applications for a Consensus Body membership can be found on the ASB site.
There is a vacancy on the Digital/Multimedia SAC. To apply, complete the OSAC Application Form.
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, which will be combined into one OSAC Registry in early 2017. 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 the status of standards or guidelines that are under consideration for the OSAC Registries, along with their status in the approval process.
Standards Documents Open for Public Comment
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.)
There is nothing available for Public Comment at this time.
Standards Documents in Public Comment Adjudication Phase
Public comment period is closed for the following standards/guidelines as OSAC units review and adjudicate comments received.

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
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 E2926-13 Standard Test Method for Forensic Comparison of Glass Using Micro X-ray Fluorescence (μ-XRF) Spectrometry
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 Documents 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.
ASTM E2548-11e1 Standard Guide for Sampling Seized Drugs for Qualitative and Quantitative Analysis
This guide covers minimum considerations for sampling of seized drugs for qualitative and quantitative analysis.
Standards Documents Returned to SDO for Modifications Based on Comments
After careful consideration of the comments from the either the public and/or other OSAC committees, the OSAC has elected to submit the following documents to the SDO for revisions prior to proceeding through the OSAC process. They believe the issues raised during the comment period can be addressed by the SDO, and intend to bring the updated standards back through the OSAC Registry Approval Process.
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
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.

Documents Approved for the OSAC Working with an SDO Process
The Biology/DNA Scientific Area Committee (SAC) recently reviewed and approved the recommendation from the Biological Data Interpretation Subcommittee to submit the following potential documents to a Standards Developing Organization (SDO). The following two projects were sent to the Academy Standards Board (ASB) at the American Academy of Forensic Sciences (AAFS).
· Validation Standards for Probabilistic Genotyping Systems
· Standards for Validation Studies of DNA Mixtures and Development and Verification of a Laboratory’s Mixture Interpretation Protocol
· The Wildlife Forensics Subcommittee sent their Wildlife Forensics Morphology Standards to ASB for review. The document will now move through the ASB process where it hopefully will be converted into an SDO approved standard. It can then be considered by the OSAC for inclusion on the OSAC Registry.
The designated SDOs will subsequently announce when these documents are available for public comment.
NFPA 921 posted to the OSAC Registry
NFPA921 is the first guideline to be posted to the Registry, a list of high-quality, science-based standards and guidelines for forensic practice.
NFPA 921: Guide for Fire and Explosion Investigations, 2014 Edition applies to the investigation of all types of fire and explosion incidents, both accidental and intentional, from residential and motor vehicle fires to multi-story high-rise fires and industrial plant explosions.
