Flame retardant test equipment is designed and developed for fire helmet safety testing, The flame retardant tester can effectively test the burning resistance of helmet. The flame retardant test equipment is manufactured according to CA 44 test standard, The GB/T 2811 safety helmet flame retardant testing machine is widely used in fire research institute, helmet production enterprises, national quality inspection dept.
The flame retardant test equipment included accessories : (1) Bunsen burner, nozzle diameter of 13mm±3mm (2) Radiation heat source (3) Platform: including helmet bracket, Bunsen lamp fixed adjustment bracket, radiation heat source stable activity adjustment bracket. (4) bolometer, thermal detector. If you are looking

Test Method for Flame Retardant Test Equipment : Fix the helmet on the bracket, Keep it in a horizontal position. Adjust the inner flame length of Bunsen burner to 25mm ~ 38mm, And then you put a radiant heat source on top of the helmet. So that the heat radiation flux obtained is 10kW/m2 ± 1kW/m2, irradiation 60 seconds, Without removing the radiant heat source, Aim the inner flame of the flame at 45° towards the test area of the cap top, Burning cap shell 15 seconds, After removing the flame, record the time from the cap flame to extinction, And check for clear signs of flame penetrating the interior of the cap.

| Place the fire helmet flame retardant performance tester flat on the ground. Keep GB/T 2812 Fire helmet flame retardant testing machine dry and clean. | | Lubricate mechanical movements for flame retardant test equipment. Turn off the electricity and gas after the test. | | The radiometer should not be placed in the high temperature induction of the chassis for a long time, so as to avoid damage caused by high temperature. After the test, the radiometer probe must be put in good order to avoid other things being damaged or damaged, which may lead to inaccurate range. | Make sure the good quality guarantee, Electronic ignition helmet testing equipment for flame resistance test, Thermocouple temperature must be placed after measuring, probe part to avoid collision and other collisions.
