Zero safety helmet impact resistance testing

Zero safety helmet impact resistance testing involves a series of rigorous and often overlooked procedures that go beyond basic certification requirements, ensuring these critical safety devices provide maximum protection in extreme conditions. Hebei PuNuosen Safety Equipment Co.,Ltd., a leading manufacturer in the safety equipment industry, has developed specialized testing protocols for yellow safety helmet price, zenith safety helmet, and zero safety helmet products, focusing on scenarios that mimic real-world hazards from construction sites to industrial facilities. These tests evaluate not just the helmet’s ability to withstand a single impact but also its performance under repeated stress, extreme temperatures, and unusual angles, ensuring reliability when it matters most.

Multi-Angle Impact Testing in Zero Safety Helmet

• Off-Center Impact Simulation: Zero safety helmet models undergo impacts at 15°, 30°, and 45° angles, targeting the weaker areas near the brim and ventilation slots. Hebei PuNuosen’s tests use a 5kg striker dropped from 1.2 meters, measuring peak acceleration inside the helmet—results consistently stay below 300g, well under the 400g safety threshold.
• Oblique Impact Resistance: The helmet’s shell and cradle are tested for oblique impacts, which can cause rotational forces on the head. Zero safety helmet from Hebei PuNuosen features a slip-resistant inner liner that reduces rotational acceleration by 25% compared to standard models, protecting against concussions.
• Edge Impact Testing: The helmet’s lower edge, often vulnerable during falls, is struck with a cylindrical striker. Zero safety helmet withstands 10+ such impacts without cracking, thanks to Hebei PuNuosen’s reinforced ABS shell design, ensuring durability in construction environments.

Temperature Extremes Testing in Zenith Safety Helmet

• Sub-Zero Impact Performance: Zenith safety helmet is frozen at -30°C for 48 hours before impact testing. Hebei PuNuosen’s specialized ABS blend remains ductile, preventing brittle fracture—a common issue with standard helmets in cold climates like northern construction sites.
• High-Temperature Degradation Checks: Exposed to 70°C for a week, Zenith safety helmet retains 90% of its impact resistance. This test validates the helmet’s performance in foundries or desert environments, where heat can weaken plastic components over time.
• Thermal Cycling Effects: Zenith safety helmet undergoes 50 cycles of -20°C to 60°C, simulating day-night temperature swings. Hebei PuNuosen’s cradle webbing (4 or 6 point Terylene) resists shrinkage, maintaining a secure fit that doesn’t compromise impact absorption.

Repeated Impact Testing in Yellow Safety Helmet Price

• Multiple Impact Durability: Yellow safety helmet price models are subjected to 5 consecutive impacts at the same location, a test beyond basic standards. Hebei PuNuosen’s design ensures the helmet absorbs energy progressively, with peak acceleration increasing by less than 15% after each impact, suitable for high-risk jobs.
• Cradle Failure Points: The helmet’s 4 or 6 point cradle is tested for  strength after repeated impacts. Yellow safety helmet price from Hebei PuNuosen shows minimal webbing stretch, ensuring the helmet stays positioned correctly even after multiple blows.
• Visor Impact Resistance: The 2mm PC visor (with anti-scratch coating) is struck 10 times with a 300g steel ball. Yellow safety helmet price visors resist cracking, maintaining visibility—a critical feature for workers in environments with flying debris.

Penetration Resistance Testing in Zero Safety Helmet

• Sharp Object Penetration: Zero safety helmet is tested against a pointed striker (5mm tip) dropped from 1.5 meters. Hebei PuNuosen’s multi-layered shell and inner foam prevent penetration, protecting against nails or rebar in construction zones.
• Blunt Object Penetration: A 2kg blunt striker with a 20mm diameter tip is used to test resistance to crushing. Zero safety helmet withstands 500N force without the striker reaching the headform, thanks to Hebei PuNuosen’s dense foam lining.
• Chisel Impact Simulation: A chisel-shaped object strikes the helmet at 45°, mimicking falling tools. Zero safety helmet deflects the impact, with the shell absorbing the force—results show no contact between the chisel and headform, a testament to Hebei PuNuosen’s design.

Zero Safety Helmet FAQS

How does zero safety helmet perform in extreme cold?

Zero safety helmet from Hebei PuNuosen is tested at -30°C, with its ABS shell remaining ductile to prevent brittle fracture. This ensures reliable protection in cold climates, where standard helmets may fail on impact.
