The instrument dedicated to the detection helmet impact absorption
properties and puncture resistance.
Preconditioning: tempering treatment, ultraviolet irradiation
pretreatment, water treatment, the above requirements can be
pre-integrated with the A705 pretreatment tank helmet shock
absorption performance test methods: the height of the drop hammer 1000mm ± 5mm; sequentially by flooding, heat, cold, ultraviolet radiation
pretreatment helmets for testing.Puncture resistance test method: puncture the cone axis so that it
passes through the center of the helmet crowns 100mm diameter weakest point within the structure, adjusting
cone tip to puncture crowns contact point height 1000mm ± 5mm, turn right after flooding, high
temperatures,temperature, ultraviolet irradiation pretreatment helmets tested.
