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 ...
The National Institute of Justice first developed standards for ballistic resistant body armor in the 1970s. The standards have been revised five times since 1984. The National Law Enforcement and Corrections Technology Center tests body armor to assess its compliance with the standards and publishes the results. [9]
A procedure for ultrasonic testing is outlined in ASTM C597 - 09. [9]In India, till 2018 ultrasonic testing was conducted according to IS 13311-1992.From 2018, procedure and specification for Ultrasonic pulse velocity test is outlined in IS 516 Part 5:Non destructive testing of concrete Section 1:Ultrasonic Pulse Velocity Testing.
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 .
The federal standard for LA abrasion testing was formally adopted by the ASTM in 1937. [10] Decades later, field studies found that the LA test results do not always correlate with reality, thus engineers outside of the United States developed different national standards like the French wet micro-Deval procedure or the British Standard 812.

At the time, variations in testing methods made comparing ceramic armor systems difficult, so the DOP test rapidly gained acceptance within the armor community after it was introduced at a research conference in 1989. By 1993, MTL's residual penetration test was officially recognized as a military standard under MIL-STD-376. [8] [17]
