The test is conducted by firing FSPs at the armour at increasing velocities until an average velocity of penetrating and non-penetrating projectiles is obtained. The fragmentation test is conducted using Fragment Simulating Projectiles (FSPs) which are available in a range of weights approximately following the binomial progression. The V50 test is the internationally recognised standard for assessing the fragmentation resistance of personal protection. To combat these threats Intelligent Armour Limited utilises a special range of Fragmentation F levels whose performance is measured by a V50 value. By altering the velocities, after a number of shots an estimate of the ballistic limit can be obtained, which is the speed up to which the material defeats the fragment.Ĭombat troops rarely suffer injury or fatality from bullets but are at high risk from primary (direct) and secondary (environmental) fragmentation. Tests according to STANAG 2920 are conducted by shooting FSPs (Fragment Simulating Projectiles) onto the test specimen with different velocities while measuring the velocity of each FSP. For instance, STANAG 2920 is used to measure Add-on-Armour systems for armoured vehicles. The measuring technique was originally developed for body armour but now see general use in all situations where fragments are the primary concern. STANAG 2920 (Ballistic test method for personal armour materials and combat clothing) is used to measure materials ability to stop fragments and shrapnel. STANAG 2920 The adoption of standards for ballistic protection levels and testing Fragmentation Test (V50 Test) Frag level Military standards for ballistic protection & armour, solutions for military applications are tested according to relevant NATO standards, normally STANAG 2920 (STANAG = NATO Standardization Agreement).
