6 SPEKTEK ALAT LABORATORIUM PENGEMBANGAN INDUSTRI TEKNOLOGI KEPOLISIAN KSA T.A. 2011. the bullet without fall. Roma Plastilina no.1 40kgs. Body armor holder must be made from plastic and functioned as framework to hold the armor vertical in front of the tray. Holder must be able to hold any armor despite of its size and model for men or women models. b. Knife and Spike Test. This test against knife and other sharp ended materials to determine the strength and reliability. The Test equipment should equipped with : 1 Knife velocity meter. Knife velocity meter must be able to measure velocity range from 3 to 8 ms with 0,02 ms accuracy. 2 Test Knife and Test Nail. Knife and nail must be made from steel and conform to drawing that has been included with weight of each piece is 0.65kg with 6.5gr accuracy. 3 Launcher. Launcher must be made of polymer in cylinder form with low friction coefficient. Completed with nail or knife holder. Launcher weight should be 1.25kg with 13gr accuracy. 4 Launcher Guide. Launcher guide is for guiding the path of free falling launcher. Launcher guide must be able to launch the knife or nail with measurable energy between 30 to 50 Joule. Launching plane of the guide must be made so the friction between guide and the launcher is negligible. 5 Body armor tray. Body armor tray must be made of steel with minimum 12mm thick and inner dimensions are 400x333x76mm. Tray is for placing silencer as armor mat. The tray must be hot dipped galvanized to prevent corrosion. Tray also completed with structures by bolts to maintain rigidity and slope from 0 to 30 deg. 6 Body armor mat. Armor mat is made of 4 layers of neoprene with each thickness is 6mm, plastazote 30mm thick, 33kgm3, 2 layers rubber 2494d, each 6mm thick. Mat dimension is conform to tray dimension, 400 x 333 mm. 7 Body armor holder. Body armor holder must be made from plastic and functioned as framework to hold the armor vertical in front of the tray. Holder must be able to hold any armor despite of its size and model for men or women models.

7. BODY SHIELD TEST

Body Shield Test Consist Of :

a. Impact Test

Giving an impact to simulate force by impact of blunt objects or if the body shield user falls from height. The specifications are : 1 Body shield is pounced to pounce material with 225 joule energy. 2 Body shield is mounted a stand which is mounted to a track that produce hit point is same for several tests. 3 Body shield mounting must be able to rotate in any degrees to enable impact test from any directions and angles. 4 Pounce material hardness is 60 HRC with pounce area is formed by an arc with 20mm radius 5 Equipped with accelerometer stand that can fit the accelerometer. 6 All parts which made of steel should made from stainless steel or hot dipped galvanize in case of the possibilty of paint removal is high 7 Completed with operation procedure. 7 SPEKTEK ALAT LABORATORIUM PENGEMBANGAN INDUSTRI TEKNOLOGI KEPOLISIAN KSA T.A. 2011.
