The VPAM BRV VR7 Edition 3 standard is a ballistic vehicle resistance standard developed by VPAM for armored vehicle testing against various caliber ammunition.  Unlike the CEN standard which only tests and certifies the material used in the construction of an armored vehicle, VPAM BRV test the whole vehicle and not just the materials used. First, the VPAM technical team analyzes the armoring design of the manufacturer in order to identify any potential weak points of the vehicle. This information is then utilized during the testing process, where the test projectiles are concentrated in perceived “weak” areas, such as the joints, doors, and pillars.  In order for a vehicle to pass and be awarded the VPAM BRV VR certification, it must defeat every single projectile fired upon it i.e. there could not be even one penetration to the vehicle. Please see VPAM Standards for the different levels of certification available.  The most common one used for commercial armored vehicles is the VR7 level certification which provides protection against 7.62 x51 and 5.56 x 45 rounds and VR9 which provides protection against armor piercing rounds, 7.62 x 51 AP or Winchester .308 AP.
