what does the impact test measure

Safety Helmet impact tester andSafety Helmet Impact Testing EquipmentXMJ-1000

Product Description

Brief Introduction

This machine specially test fire helmets impact resistance performance, can also do the antipenetration properties test.

Determination of fire helmets impact resistance performance, put the special head model with a

good helmet(aluminummagnesium alloy materials) installed in the high sensitivity of the sensor,

then use the 5kg hammer from 1 m height of impact, and the high sensitivity strength induction device

detect the impact instantaneous force value to judge helmet shock absorption performance is good or bad.

Determination of the helmet antipenetration properties test, first fix the head model on the base,

make head model,Steel cone and electrical contact display device to form a closed circuit, then put

3kg steel cone from 1 m height fall to puncture helmet, after puncture observation electrical contact

display device. Judge helmet antipenetration properties is good or bad..

The equipment meet the national standard:

GB2811-2007 Safety Helmet

GB/T2812-2006 Safety Helmet Test Method
