What are the armoring standards?

Numerous international organizations have developed armoring standards – – defeat levels and testing procedures. In the USA for instance, the standards were developed by the National Institute of Justice (NIJ), a procurement arm of the US government (see below).
In Europe, the European Union developed their standard, called CEN, which is the B-Level standard. Other countries too have developed their own standards. International Armoring Corporation® and Armormax® generally adheres to the European Union’s standard because it is more specific to the requirements of armored passenger vehicles. Over the years more and more people are associating the NIJ standards with body armor while the B-ratings can be applied to vehicle protection.
Armor vehicles are standardized in terms of the following acronym example/s:
- BR6
- FB6
- VR6/VR7
Armoring standards for armor vehicles are represented by ‘’BR’’. This is the abbreviation for ‘’Ballistic Resistance’’ that is the protection level of transparent armor or bulletproof glass of armored vehicles. It is defined in the standard of DIN EN 1063.
DIN EN 1522 is the standard for the protection level of opaque material of an armored vehicle such as aramids, ballistic steel, UHMwPE, ceramics, armormax, etc.
The VR is defined in the standard of BRV 1999 that itemizes the overall protection level of a complete armor vehicle.
These protection levels for armor vehicles are defined by numerous international organizations. National Institute of Justice (NIJ) develops armoring standards for the USA. Similarly, CEN is the standards developed by the European Union that are considered B-level standards.
