BODY ARMOR TEST Laboratorium Alat dan Material Khusus Almatsus

5 SPEKTEK ALAT LABORATORIUM PENGEMBANGAN INDUSTRI TEKNOLOGI KEPOLISIAN KSA T.A. 2011. Helmet is mounted to head figure which is mounted to a track that produce hit point is same for several tests. Pounce material hardness is 60 HRC with pounce area is formed by an arc with 20mm radius. Equipped with accelerometer that can measures 600g in 1msec and can be detachable for other measurements. 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. b. Penetration Resistance Test. To determine the helmet strength against sharp ended objects. The equipment is consisted of stabbing system, head figure as helmet mounting, and sensor for determine whether helmets are perforated or not. Stabbing system could produce 90 Joule energy when stabbing. Stabber must have 60 HRC hardness and the tip point dimension are 0.5mm radius at 60 degree. Helmets mounting are form as similar as human’s head to give the better simulation. Sensor should be able to giving signals when the penetration is able to pierce the helmets or when it is not. 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. c. Tension Test. Determine the strength of tightening rope of the helmets by giving tension to rope when it is locked. The strength is determined by observing the elongation of rope. Consisted of the pulling system and head figure as helmets mounting. Pulling system is operated by air pneumatic and can produce force Initial force of 25kgf to be held for certain times, and Advanced force of 150kgf to be held for another certain times. Equipped with elongation gauge or distance meter to determine and record the elongation of rope at initial and advanced force. d. Face Shield Drop Test. Face Shield Drop test giving a hit to face shield of the helmet and observing the after effect for the user. Face Shield Drop test consisted of pounce system and head figure as helmet and sensor mounting. Pouncer system could produce energy of 10 Joule. Pouncer is mounted to a track that led the pouncer to hit the same position of the face shield for several tests. Pouncer material hardness is 60 HRC with pouncer area is half spherical of 45mm diameter. Helmets must be mounted so the pouncer will hit the face shield perpendicularly. Sensor is set to measure deflection and positioned behind the face shield at the exact position the pouncer hit. 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. e. Light Transmission Test. Light Transmission test to compare light intensity with and without passing the face shield. Light Transmission test consisted of light source, luxmeter, face shield mounting, and dark room. Light source, face shield mounting and luxmeter are positioned as one optic path and the distance between those components can be adjust easily. Light source, face shield mounting and luxmeter shoule be enclosed by a box to perform as dark room. The box should be able to open easily and the inner material is made of non-reflecting material and painted black. f. Completed with operation procedure.

6. BODY ARMOR TEST

Body Armor Test consist of : a. Shoot Test. This test is to test body armor against any caliber bullets from any distance to determine body armor strength and reliability. The Equipment should have : Body Velocity Meter, Body Armor Tray, Body Armor Holder, Calibrating System of body armor tray and Test room wall cover. Bullet velocity meter can measure the bullet velocity from certain distance and show the result through display monitor and connected to a printer. Body armor tray must be made of steel with minimum 12mm thick and inner dimensions are 420x350x100mm. Tray is for placing Roma Plastilina as body armor’s mat. The tray must be hot dipped galvanized to prevent corrosion. Tray also completed with pedestals by bolts to maintain rigidity and height as 150 to 180cm from the ground. The pedestals is bolted to ground and must be withstand 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.
