Review of Ballistic standards NIJ = United States National Institute of Justice standard International / Local standards Levels IIA, II and IIIA protect against hand guns Levels III and IV protection against rifles

MIL STD and STANAG NIJ = V0 standard, stop pass/no stop fail Ballistic resistance of body armor NIJ std Mil Std 662E (USA) and STANAG 2920 (NATO) are V50 standards using a FSP (fragment simulation projectile) (17gr FSP)

Stab resistance armor US STD NIJ Resources/Attachments/760/ pdf United Kingdom PSDB Anti stab and anti spike are different Solutions can be woven, chainmail, platelets, steel, aluminium, titanium wire

Manufacturers’ art Firstly to meet the specified standard To construct the best functional carrier The produce the lightest, most flexible and most comfortable solution To provide a cost effective package

Selecting body armor Chose the correct Level of protection Select only independently certified armor Balance weight and flexibility versus price Allow the manufacturer to use their skills Consider breathability and comfort Chose a reputable manufacturer

Measurement of Performance The V50 is usually used as the basic measurement of performance V50 is the 50% probability of penetration of defined bullet type expressed in terms of velocity in m/sec (or in the USA fps) Areal weight is also used and this is expressed in terms of kg/m2 (or in the USA lbs/ft2) Sometimes these two references are used to express a RPI (Relative Performance Indicator) V50 divided by A/D – This enables comparative evaluation between armor types

Blunt Trauma The US National Institute of Justice Standard is 44 mm maximum depth of indentation on the body side, or trauma, measured on a clay similar to Roma Plastilina #1 Body armor solution= protection x comfort

International Standards BFS CountryBlunt Trauma Level US NIJ<44mm UK PSDB<25mm German Schutzklasse<25mm and 40mm Belgium<20mm Netherlands KLPD<20mm Sweden RPS<25mm

Hard armor plates Hard armor plates are designed to defeat high velocity rifle rounds NIJ Level III and NIJ Level IV Materials= steel, ceramic or UHMWPE (Ultra High Molecular Woven Poly Ethylene)
