Review of Ballistic standards NIJ the most common standard, but many National standards exist Levels IIA, II and IIIA cover hand guns Levels III and IV cover rifles

NIJ Standard 0101. 04 NIJ LEVEL BULLET TYPES IIA 9 mm FMJ, . 40 S & W II 9 mm FMJ, . 357 Mag JSP IIIA 9 mm FMJ, . 44 Mag SJHP III 7. 62 x 51 NATO FMJ IV . 30 M 2 AP Go to www. nlectc. org for full definition of NIJ protocol

MIL STD and STANAG NIJ = V 0 standard, stop pass/no stop fail Mil Std 662 E (USA) and STANAG 2920 (NATO) are V 50 standards using a FSP (fragment simulation projectile) (17 gr FSP)

Anti Stab Armor US STD NIJ 0101. 15 , UK PSDB Anti stab and anti spike are different Solutions can be woven, chainmail, platelets, steel/aluminium/titanium wire

Manufacturers’ art l l 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 against price Allow the manufacturer to use their skills Consider breathability and comfort Chose a reputable manufacturer

Measurement of Performance The V 50 is usually used as the basic measurement of performance V 50 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/m 2 (or in the USA lbs/ft 2) Sometimes these two references are used to express a RPI (Relative Performance Indicator) V 50 divided by A/D – This enables comparative evaluation between armour 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 Country Blunt Trauma Level US NIJ <44 mm UK PSDB <25 mm German Schutzklasse <25 mm and 40 mm Belgium <20 mm Netherlands KLPD <20 mm Sweden RPS <25 mm

Hard Armour Plates Hard armour plates are designed to defeat high velocity rifle rounds NIJ Level III and NIJ Level IV Materials= steel, ceramic or UHMWPE
