NIJ Lays Out Body Armor Standards and Minimum Requirements
The National Institute of Justice (NIJ) first began testing and producing body armor (safety vests) and performance criteria for ballistic and stab resistance during the mid-1970s. And, since that time, the lives of more than 3,000 officers were saved.

Law Enforcement Around The Globe Accept NIJ Standard
This NIJ standard is widely known and accepted by police agencies all throughout the world. Thus, the standard is the performance scale for all ballistic-resistant bulletproof vests.

Understand, as it stands, there are currently no bulletproof body vests available on the market. Body armor does give protection to the wearer from various kinds of handgun ammunition. However, officers should always remember that armor’s threat level is classified and rated differently. 

When certain officers – Special Operations officers, hostage rescuers and SWAT team members – face a weapon threat that is greater than regular body armor can provide, they should wear additional protection.

Minimum Requirements Of Body Armor
The NIJ standard lays out what the minimum requirements are for performance and testing methods for all personal body armor and rates the various kinds of available body armor and notes the many threat levels.

When body armor is being tested, self-regulating NIJ-certified laboratories will put the body armor through various tests to ensure they are up to NIJ code and performance standards.

The NIJ has the authority to retest body armor already on the manufacturer’s floor to ensure performance standards are up to code as time passes. This is part of the NIJ’s excellence and audit procedure.

Their performance standards means commercially available body armor will meet the minimum performance requirements it sets forth. In fact, personal body armor’s ballistic and stab resistance standards have been published by the NIJ. An overview of both the NIJ 0101.04 Standard as the NIJ 0101.06 Standard can be found below.
