【Scope of application】:
Developed according to the latest national standard GB/T 2812-2006 "Testing Methods for Safety Helmets", used to test the impact absorption performance of safety helmets and puncture performance testing of safety helmets, widely used in the supervision and inspection of special labor protection products Stations, Architectural Research Institutes, Construction Engineering Testing Stations, Electric Power Departments, and Safety Helmet Manufacturers.
【Related Standards】:
GB/T 2812-2006 "Test Methods for Safety Helmets", GB/T 2811-2007 "Safety Helmets"
【technical parameter】:
1. Impact drop hammer: the weight is 5-5.01kg, the hammer head is hemispherical, the radius is 48mm, and the material is 45# steel
