Headphone flame retardant testerMade in accordance with standard clauses such as GB/T31422:6.4.1.12, BS EN 352, BSEN13819:4.13.3, etc., for flame retardant testing of ear cushions and headphones for hearing protectors.
Using a heating steel rod with a length of (300 ± 3) mm and a diameter of 6mm, heat the steel rod at least 50mm from the bottom to (650 ± 20) ℃. The steel rod should be vertical and the temperature at a distance of 20mm from the bottom should be (650 ± 20) ℃. Then, make the bottom close to the surface of the earmuff, keep the steel rod vertical, and apply pressure based on its own weight. Keep any part of the earmuff of the hearing protector in contact for (5 ± 0.5) seconds without burning, and the earmuff should not be flame retardant after removing the heating steel rod.
