Wholese forest fire helmet

   1. Wildland Fire Helmet Appearance quality: The surface of the cap shell should be bright and clean, without stains, bubbles, defects and other defects that impair the appearance; the surface of the mask should be free of obvious scratches or shaved marks, and the periphery should be smooth and free of edges and corners; shawl seam The system should be flat, and there should be no defects such as off-line, skipped stitches, damage, and stains; the installation of each part of the helmet should be in place, firm, and correct, without loosening or slipping. The mask should be flexible to stretch or flip, and the shawl should be easy to take off.

   2. Thermal stability performance: At a temperature of 180°C, after 5 minutes, the edge of the Rescue Helmet is not deformed, the hard accessories remain functional, and the surface of the reflective material is free of carbonization and shedding.

   3. Flame retardant performance: After the fire source leaves the cap shell, the self-extinguishing time from the fire is 0S in front, 0S in the rear, 0S on the left, and 0S on the right.

   4. Shock absorption performance: high temperature (50℃, 4h): the impact force is 3529N. Low temperature (-28℃, 4h): impact force is 3714N, immersion in water (immersion in water tank at room temperature, 4h): impact force is 3577N.

   5. Penetration resistance: low temperature pretreatment (-28℃, 4h): the steel cone does not establish electrical contact with the head mold.

   6. Electrical insulation performance: the leakage current of the cap shell is 0.12mA.

   7. Lateral rigidity: the maximum deformation of the cap shell: 26mm, and the deformation after unloading: 5mm.

   8. Tensile strength of the chin strap: the chin strap has not broken or slipped, and the extension length is 8mm.
