Ballistics Overview • Review of common ballistic materials • Typical vest construction • Review of ballistic standards • Anti stab armour • The vest manufacturer’s art • Blunt Trauma
Ballistic materials Hard armour ** 10 x 12 inch combination plate
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 Go to www.nlectc.org for full definition of NIJ protocol
MIL STD and STANAG • NIJ = V0 standard,stop pass/no stop fail • Mil Std 662E (USA) and STANAG 2920 (NATO) are V50 standards using a FSP (fragment simulation projectile) (17gr 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 • 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 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 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
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
