Flame retardant test canvas safety requirements
Scope Applications:
Fabric, clothing, textiles
Sample size / Quantity template requirements:
5 pieces 51 × 152mm (2 × 6 in.)
Performance Requirements
Judgment requirements
① Sample with no plexus on the surface: first test to determine the burning rate of the sample in the longitudinal and latitudinal directions, respectively, and the speed in the longitudinal direction of the test sample
② surface hairless plexiglass sample: the direction of the hair bundle as the sample of the long direction. Fire and application between: Busen or tirrill burner (flame height: 1.5inch)
(1) The average length of the burning of the sample shall not exceed 6 inches. The average burning time after removing the ignition source shall not exceed 15 seconds. The average burning time of the falling objects on the sample shall not exceed 3 seconds.
(2) The average length of burning of the sample shall not exceed 8 inches. The average burning time after the ignition source is removed shall not exceed 15 seconds, and the average burning time of falling objects on the sample shall not exceed 5 seconds.
CA117
Section E
Scope Applications:
Fabrics, decorative fabrics
, Sample size / Quantity The sample requires each 10 pieces of washed and unwashed 51 × 152mm (2 × 6 in.)
Performance Requirements
Judgment requirements
① Sample with no plexus on the surface: first test to determine the burning rate of the sample in the longitudinal and latitudinal directions, respectively, and the speed in the longitudinal direction of the test sample
② surface hairless plexiglass sample: the direction of the hair bundle as the sample of the long direction. Butane gas 1s
A smooth surface of the textile:
1) When the sample flame spread time is not less than 3.5 seconds, that is, good fire performance;
2) When the flame spread of the sample is less than 3.5 seconds, the textile is flammable and unsuitable for clothing.
2. The surface of the fibers of the textile fibers:
1) When the flame propagation time of the sample is more than 7 seconds or the surface is burned for 0 to 7 seconds, it indicates that the fire is not enough to ignite, carbonize and melt the sample, that is, the sample has good fireproof performance and normal burning performance;
2) When the sample flame spread time is 4 to 7 seconds, including 4 seconds and 7 seconds, and the back is ignited, carbonized, melted, then the sample is considered to have combustion performance between (1), (3) ;
When the sample flame spread time is less than 7 seconds, and the flame is intense enough to ignite, carbonize, melt the back of the sample, it is considered fast and severe flammability.
Flame-retardant fabrics in the prevention of fire has a good protective effect, fire-retardant overalls can effectively reduce the fire and sputter metal droplets on the human body injury - YuLong Safety
