PENETRATION RESISTANCE
Penetration resistance shall be measured according to EN 863 at velocity of (100± 10) mm/min. Five tests shall be made distributed throughout the zone of protection of the knee protector, including potentially weak points. The test spike shall be applied to the outer face of the knee protector. The maximu deflection of the inner face of the knee protector shall be measured by a method having a resolution of < 0,5 mm.
FORCE DISTRIBUTION-knee Pads
When tested according to 6.6 the mean force recorded by each transducer shall be less than 30 N in the tests on the flat anvil.
PULLING FORCE-Tool Bag
When test the bag, we shall meet below two requirement:1. 600D fabric pulling force shall be no less than 200N. 2. 168D fabric pulling force shall be no less than 320N.
PEAK TRANSMITTED FORCE-Knee pads
When tested in accordance with 6.7 the peak transmitted forces in test impacts shall not exceed the values in Table 3 inimpacts at the energies given in Table 3.
IMPACT TESTING-Tool Bag
Tool bags shall be impacy-tested by loading 15kgs for handle straps and 10kg for shoulder strap with distance of travel is 150±5mm & frequency is 20±2times/min, the shaking impact test should be no less than 1000 circles.
IMPACT TESTING-Knee Pads
Knee protectors shall be impact-tested with a falling massin a vertical guidance system that allows the terminal velocity of the falling mass to be measured and to be within ± 2 % of the required velocity. The total mass shall be (2 500 ± 100) g including a flat faced steel striker (80 ± 1) mm in diameter.
