NIJ Releases New Body Armor Standard

One important statement was placed in the Forward.

“Publication of this revision of the standard does not invalidate or render unsuitable any body armor models previously determined by NIJ to be compliant to either the NIJ 2005 Interim Requirements or the NIJ Standard–0101.04 Rev. A Requirements. While it may not necessary to remove these existing armors from service, agencies are advised to always require their procurements to meet or exceed the most recent and up-to-date version of this standard.”

One reader’s initial perusal identified the following changes:

1. Removal of Type I standard
2. New as well as conditioned armor shall be tested
3. Type IIA projectile velocities higher
4. Ranges for all velocities (acceptable velocity error levels), new velocities for most levels is “(old value+error) +/- error” …so the mins are the same as the old values
5. New level added – Type IIIA for high powered handguns (.357 SIG and .44 mag)
6. Added diagram for helping determine penetration depth – just a format change to the document
7. Requirements added for testing systems with and w/o plates “in conjunction armor” when the inserts are removable
8. Changed the terms used for designating penetration
9. Multiple sizes of armor vests shall be tested
10. Conditioning requires tumbling vest and humidity/water exposure
