Is expired safety helmet still available after inspection?
Glass steel (vinylon steel) rubber cap is more than three and a half years. More than to do testing, testing qualified can continue to use, but still after regular inspection, the cycle seems to be a month, if a test failed, then batch batch scrapped.
The life of the helmet: calculated from the date of manufacture of the product. Woven sticks of plant sticks, no more than two years. Plastic cap, paper glue cap, not more than two and a half years.
