安全帽技术性能要求

作者[孙锡云] 发表于[2011-5-11 11:26:00]

安全帽技术性能要求

一、基本技术性能要求

1 冲击吸收性能

GB 2812中规定的方法进行试验:5公斤重的钢锤从1高度自由落下,传递到头模上的力不超过4900N500kgf),这是人体颈椎在受力时的最大限值,超过此限值颈椎就会受到伤害,轻者引起瘫痪,重者危及生命。

2 耐穿刺性能
  以GB 2812中的规定进行试验:3公斤重的尖物从1高度自由落下,检测尖物坠落在帽壳上时穿不透的性能。

二、特殊技术性能要求

1 电绝缘性能

GB 28126章中的规定进行试验,泄漏电流不超过1.2毫安。

2 阻燃性能

GB 28127章中的规定进行试验,续燃时间不超过5秒。

3 侧向刚性

GB 28128章中的规定进行试验,最大变形不超过40毫米,残余变形不超过15毫米

4 抗静电性能
  以GB 28129章中的规定进行试验,实际测得的表面电阻率不大于1×10欧姆。
