5.10 flame retardant performance:
Total detection 4 masks. 2 after pretreatment temperature,2 are not preprocessed.
Temperature pretreatment conditions:
a) (70 ±3)° c air in 24 hours
b) (-30 ± 3)° c air in 24 hours
After the pretreatment temperature should resume at room temperature for at least 4 hours.
Single burner test carried out in accordance with the following procedure, the results should be in accordance with 4.11 provides. Mask to wear on the metal die, die movement measurement at the nose line speed (60 ±5)mm/s.
Die through adjustable propane burner location. Burner top and the lowest part of the mask (as direct when placed on a burner) should the distance be set (20 ±2)mm.
Will die from the region adjacent to the burner, open propane gas, pressure regulator to 20000~30000Pa (0.2bar~0.3bar) and light the gas. Through the needle valve and carefully adjust the supply pressure, flame height adjustment (40 ±4)mm. Above the temperature of the flame at the burner tip (20 ± 2)mm1.5mm diameter metal thermocouple probe for measurement of isolation, should be (800 ±50)??.
Die set into motion and record a mask through the flame effect. Should repeat the test with a view to evaluation in masks all external material.Should any component through the flames only once.
5.11 skin irritation
In accordance with the GB/T 16886.10 method under test, the result shall conform to this standard 4.12 provisions of articles.
5.12 identity and user's manual
Visual inspection, shall comply with 4.13 the provision.
