Test Standards now define how many shots must be used to estimate a v 0 for the armor certification. This procedure defines a confidence interval of an estimate of v 0. (See "NIJ and HOSDB test methods".) 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 ...
EN 1063, or CEN 1063, is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet-resistant glass. It is commonly used in conjunction with EN 1522 (Euronorm standard for Bullet Resistance in Windows, Doors, Shutters and Blinds) to form a ballistic classification system by ...
NATO AEP-55 STANAG 4569 is a NATO Standardization Agreement covering the standards for the "Protection Levels for Occupants of Logistic and Light Armored Vehicles". [ 1 ] The standard covers strikes from kinetic energy , artillery and IED blasts .
This test is performed under normal conditions at 21 °C (70 °F), but also by simulating cold polar −54 °C (−65 °F) or hot desert 52 °C (126 °F) conditions using special cooling equipment and ovens to cool or heat the ammunition under test to the appropriate levels of humidity and temperatures required.

The current standard HOSDB Body Armour Standards for UK Police (2007) Part 3: Knife and Spike Resistance is harmonized with the US NIJ OO15 standard, use a drop test method and use a composite foam backing as a tissue simulant. Both the HOSDB and the NIJ test now specify engineered blades, double-edged S1 and single-edge P1 as well as the spike.

By Lidia Kelly (Reuters) -Russia is boosting its ballistic arsenal with new strategic missile systems, plans maximum-range launches and may increase testing in response to growing external threats ...
The standard plates are not given an NIJ rating, as they are tested in accordance with specific protocols for the military and not the NIJ's testing. Military testing calls for survivability of three hits from the round marked on the plate - for standard SAPI, of a caliber up to 7.62 NATO M80 ball and of a muzzle velocity up to 2,750 ft/s (840 ...
