Understanding NIJ Standards 0101.07 and 0123.00: Enhancing Body Armor Performance

In the world of law enforcement, personal safety is of paramount importance. Police officers and other law enforcement personnel rely on body armor to protect themselves from daily dangers. To ensure the highest level of protection, the National Institute of Justice (NIJ) continuously updates its standards for body armor. In this blog, we will explore the latest developments in NIJ Standards 0101.07 and 0123.00, shedding light on the crucial changes and improvements made to enhance the performance and safety of body armor used by U.S. law enforcement agencies.

NIJ Standard 0101.07: A Comprehensive Upgrade

NIJ Standard 0101.07, titled "Ballistic Resistance of Body Armor," represents a significant revision to its predecessor, NIJ Standard 0101.06, published in 2008. This standard is a comprehensive guideline for testing, evaluating, and certifying ballistic-resistant body armor, primarily used by U.S. law enforcement agencies to safeguard the torso against handgun and rifle ammunition.

One key aspect of this standard is its role in the NIJ Compliance Testing Program (CTP). It provides the necessary framework for testing and certification of body armor, ensuring it meets the highest performance requirements. Ballistics laboratories and body armor suppliers participating in the NIJ CTP rely on this standard to ensure the quality and effectiveness of their products.

Harmonizing with ASTM Standards

A notable change in NIJ Standard 0101.07 is incorporating standardized test methods and laboratory practices published by ASTM (American Society for Testing and Materials). This collaborative effort between NIJ, the U.S. Army, NIST (National Institute of Standards and Technology), and other stakeholders aims to harmonize testing procedures and practices related to ballistic resistance.

By referencing ASTM standards, NIJ aligns itself with widely recognized practices, benefiting both law enforcement and military ballistic-resistant armor and equipment. This alignment allows for consistent testing methodologies, giving end-users greater control over product specifications and ensuring equipment's effectiveness against specific threats.

Revising Ballistic Threat Levels

In a significant shift, NIJ Standard 0101.07 no longer lists ballistic test threats within its text. Instead, these threats are now defined in a separate document, NIJ Standard 0123.00, titled "Specification for NIJ Ballistic Protection Levels and Associated Test Threats." This new document specifies the ballistic threats identified by U.S. law enforcement as representative of current prevalent threats in the United States.

NIJ Standard 0123.00 serves as a companion to NIJ Standard 0101.07, offering a clear reference for testing and evaluating ballistic-resistant equipment. It covers a wider range of rifle threats and introduces new threat level nomenclature for better clarity and understanding, as shown in Table 1 below:

Table 1: New Threat Levels
  • NIJ Level II ➡ NIJ HG1 (HG = handgun)
  • NIJ Level IIIA ➡ NIJ HG2
  • NIJ Level III ➡ NIJ RF1 (RF = rifle)
  • NA ➡ NIJ RF2 (an intermediate rifle protection level)
  • NIJ Level IV ➡ NIJ RF3

These changes streamline the standards, making them more accessible and user-friendly for law enforcement professionals.

Improvements for Female Armor

NIJ Standard 0101.07 also introduces enhancements to the testing methods for body armor designed specifically for women. These improvements address the unique challenges of female body armor, ensuring better performance and fit. Notable changes include the use of new clay appliques to ensure proper contact with nonplanar panels and revised shot requirements to assess shaping features.

Shot placement has been reconfigured to account for potential vulnerabilities in the panel's construction and angle of incidence near the edges. These changes aim to provide female law enforcement officers with body armor that offers optimal protection and comfort.

Perforation-Backface Deformation (P-BFD) Testing

The P-BFD testing in NIJ Standard 0101.07 has also undergone updates. Soft armor panels now face an additional shot when subjected to P-BFD testing. This change addresses the unique behavior of soft armor when struck by handgun projectiles near the top edge of the front armor panel.

For soft armor, the standard introduces a shot at the top center with a 45° angle of obliquity between the shot and the armor item. This ensures that soft armor performs adequately in critical areas.

Furthermore, P-BFD testing for hard armor plates now includes shots to the "crown" of curved plates, an area that may be more vulnerable to penetration due to material characteristics. This aligns the NIJ standard with U.S. Army testing practices, enhancing consistency and reliability.

NIJ Standard 0123.00: Defining Ballistic Protection Levels

NIJ Standard 0123.00, titled "Specification for NIJ Ballistic Protection Levels and Associated Test Threats," is a groundbreaking publication. It defines the ballistic protection levels and test threats identified by U.S. law enforcement as representative of current prevalent threats in the United States.

Unlike its predecessors, this standard does not include performance requirements or specified test methods. Instead, it serves as a reference document to be used alongside other standards for testing and evaluating various ballistic-resistant equipment, including body armor. The modularity of this approach allows NIJ to remain responsive to evolving threats while reducing administrative burdens.

By separating the protection levels and test threats from specific equipment standards, NIJ promotes interoperability among standards applicable to ballistic-resistant equipment. This approach simplifies updates and ensures that protection levels and test threats remain consistent across distinct types of equipment.


NIJ Standards 0101.07 and 0123.00 represent significant advancements in the field of body armor testing and evaluation. These standards enhance the safety and protection of U.S. law enforcement officers by providing a clear framework for certification and testing. The inclusion of ASTM standards, the revision of ballistic threat levels, and improvements for female armor ensure that law enforcement personnel have access to the highest-quality body armor that meets the demands of modern threats.

As law enforcement continues to evolve, these standards will play a crucial role in ensuring the safety and effectiveness of body armor, ultimately contributing to the well-being of those who serve and protect our communities.
