List of body armor performance standards - Wikipedia

v 0 is difficult to measure, so a second concept has been developed in ballistic testing called the ballistic limit (v 50). This is the velocity at which 50 percent of the shots go through and 50 percent are stopped by the armor. US military standard MIL-STD-662F V50 Ballistic Test define a commonly used procedure for this measurement.

Abstract : Perforation performance of body armor is typically evaluated by V50 ballistic limit testing. Shot velocities are sequentially controlled by a up/down method to populate a sample containing results on both sides of the true value of the V50 velocity. The V50 velocity is the velocity at which the probability of perforation is 50 percent.

Explanation of V-50 Testing - Bullet Proof ME

The velocity of the bullets where 50% of the bullets DON'T penetrate, and 50% of the bullets DO penetrate is the V-50 rating for that ballistic protection. So, V-50 is a good measure of the UPPER limit of protection, or the "breaking point" for armor. You would want a V-50 velocity rating somewhat HIGHER than you would want for a Pass/Fail test ...
