The National Institute of Justice published Addendum 3 to NIJ Standard 0101.07 on November 25, 2025. The document provides revisions and clarifications to the core standard and to both Addendum 1 and Addendum 2, which preceded it. Addendum 2 had itself been published on July 1, 2025, where it clarified that the standard's scope covers armor designed specifically for the human torso. Addendum 3 builds on that foundation. According to NIJ, the clarifications in the addenda stem from ongoing interactions with accreditors, manufacturers, and material suppliers — meaning the revisions reflect real-world implementation questions that arose after the base standard was first adopted.
NIJ Standard 0101.07 replaced the previous 0101.06 standard, which dated to 2008. The NIJ has issued six revisions to its body armor standards in total since the initial version was published in 1972. That history matters here: each revision has tracked the evolution of ballistic threats, and 0101.07 continues that pattern by introducing the RF2 intermediate threat level to address risks not captured by older protection categories.
The standard itself is structured into fourteen distinct sections and eight appendices, according to the document. It specifies minimum performance requirements and test methods for body armor intended to protect the human torso against both handgun and rifle ammunition.
The Role of NIJ Standard 0123.00 and the RF2 Threat Level
One of the more consequential structural changes in the 0101.07 framework is the separation of ballistic protection levels into a companion document, NIJ Standard 0123.00. That standard now defines ballistic protection levels and their associated test threats, which were previously folded into the core body armor standard. NIJ said the separation is intended to reduce confusion among law enforcement purchasers and officers — a practical acknowledgment that combining threat-level definitions with test methodology in a single document created interpretive problems in the field.
The two standards are designed to be used together. NIJ Standard 0101.07 addresses life-threatening safety hazards posed by modern firearms, and NIJ Standard 0123.00 supplies the threat taxonomy that gives 0101.07's test requirements their operational meaning. Agencies reviewing procurement specifications or updating their ballistic protection policies need both documents.
Within that framework, the RF2 intermediate threat level is new to 0101.07. NIJ introduced it to address evolving ballistic risks that fall between existing protection categories. The specific ammunition threats tied to RF2 are defined in NIJ Standard 0123.00.
Testing, Accreditation, and the Compliance Infrastructure
Two separate programs use NIJ Standard 0101.07 as a foundational reference. The NIJ Compliance Testing Program evaluates and certifies commercially available ballistic-resistant equipment against the standard's requirements. Separately, the National Voluntary Laboratory Accreditation Program uses 0101.07 to accredit ballistics laboratories that conduct the underlying physical testing.
NIJ collaborated with industry stakeholders and the Criminal Justice Testing and Evaluation Consortium to refine the standard based on contemporary ballistic threats, according to NIJ. That collaboration shaped not just the threat-level structure but also improvements to test methods for armor designed for female officers — a specific area where the updated standard introduces refinements. The nature of those methodological changes is detailed within the standard's fourteen sections and appendices.
The addenda framework means that laboratories, manufacturers, and purchasing agencies must track not just the base 0101.07 document but the three addenda issued to date. Each addendum carries equal weight in the compliance process. NIJ has advised agencies to incorporate the revisions found in all three addenda as part of their compliance and procurement review processes.
What Agencies Should Do Now
For agencies in the middle of a procurement cycle or scheduled uniform replacement, the November 25, 2025 publication date for Addendum 3 creates a clear action item. Any solicitation or specification written against NIJ Standard 0101.07 without reference to all three addenda may not reflect the current state of the standard. Procurement officers should verify that specifications cite the base standard and all addenda, and that any armor under evaluation has been tested under the full current framework.
Laboratories seeking or maintaining NVLAP accreditation and manufacturers participating in the NIJ Compliance Testing Program face the same obligation: testing protocols must account for the clarifications introduced through all three addenda, including those addressing female officer armor and the RF2 threat level.
NIJ's ongoing engagement with accreditors and material suppliers suggests further clarifications remain possible. The six-revision history of the body armor standards program, stretching back to 1972, indicates that addenda and revisions are a routine feature of the standards lifecycle rather than exceptional events. Agencies that treat the published standard as a static reference risk falling behind the compliance baseline.
