As a traditional Chinese medicine armor to ensure safety, safety helmets are divided into glass fiber reinforced plastic safety helmets, polycarbonate plastic safety helmets, ABS plastic safety helmets, ultra-high molecular polyethylene plastic safety helmets, modified polypropylene plastic safety helmets, tape miner safety helmets, Plastic miners' helmets, cold-proof helmets, paper glue helmets, bamboo full hats, other woven helmets, etc.
The testing content of safety helmet is not as simple as that of safety jacket and safety vest, and the testing items and standards of safety helmet mainly include the following:
Test items:
Impact absorption performance, puncture resistance performance, strength without chin strap, anti-static performance, electrical insulation performance, lateral rigidity, flame retardant performance, low temperature resistance performance, etc.
Testing standard:
AQ/T 1105-2014: Mine rescue protective clothing
