7. Collision energy absorption performance at high temperature: high temperature (50 ~plusmn);2℃，4h) After pretreatment, the helmet is worn on the corresponding head shape and raised to1000mm±5mmSelection2Where the distance is not less than or equal to120mmEach falls freely once.Cracks do not appear in helmet housing
8. Collision energy absorption performance at low temperature: through low temperature (-10 ~plusmn);2℃，4h) After pretreatment, the helmet is worn on the corresponding head shape and raised to1000mm±5mmSelection2Where the distance is not less than or equal to120mmEach of them falls freely once, and no cracks appear in the helmet case.
9. Collision energy absorption performance of rain shower: through rain shower (spraying water volume 15L/min,1h) After pretreatment, the helmet is worn on the corresponding head shape and raised to1000mm±5mmSelection2Where the distance is not less than or equal to120mmEach of them falls freely once, and no cracks appear in the helmet case.
10. Penetration resistance: steel cone with a mass of 3 kg.1000mm±5mm,Experiment2Secondary, spacing not less than75mmThe steel cone does not penetrate the helmet in contact with the head
11. Weatherability of helmet: Fixed the helmet sample on the test stand, the radiation intensity of the helmet is 1000W/m2, and the deviation of radiation intensity is not greater than & plusmn.10%Blackboard temperature63℃±3The relative humidity is 0.65%±5%The spraying period is18min/102min(Spray time)/No water spraying time, per24hFor a cycle, irradiation20h,Stop photo4hContinuous7After three cycles, there was no obvious erosion, deformation and discoloration on the outer surface of the helmet.
