【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
2. Puncture cone: the quality is 3-3.05kg, the cone angle of the puncture part is 60°, the cone tip diameter is 1mm, the length is 40mm, the maximum diameter is 28mm, and the hardness is HRC45
3. The height of the falling weight: 1000mm, the height of the falling weight can be adjusted
4. Force measuring system: using dynamic force sensor, measuring range 0-20KN, corresponding minimum frequency 5kHz, ±2.0% of the full range, accurate to 1N
5. Equipped with 1#, 2# aluminum-silicon alloy test special head mold each (in accordance with GB/T 2812-2006 Appendix A)
6. The release point of the electromagnet can be adjusted up, down, left, and right arbitrarily as needed
7. Bench: The suspension and release of impact drop hammer and puncture drop hammer are controlled by electromagnet automatic pull-in method
8. Base: with impact resistance, can firmly install the load cell
9. Piercing alarm device: When the piercing cone contacts the head mold, the equipment will sound a whistle and flash a light to indicate
10. LED digital display, accurate to 1N, automatically save the maximum force value (standard); optional touch screen control, display force value curve (optional)
11. The special guiding system can automatically guide the impact point to ensure that the impact position is the center point of the helmet
