GB 8965.1-2009 "Protective clothing flame retardant protection Part 1: flame retardant clothing" instead of GB 8965-1998, implemented on December 1, 2009.
Comparing the new national standard with the old one, the main changes are as follows:
L aramid fabric has added durable flame retardant material index and thermal protection coefficient index (TPP):
Thermal protection performance refers to the thermal energy value of the second degree burns caused by the fabric. The higher the TPP value, the stronger the thermal protection performance of the fabric.
The flame retardant properties of L fabrics are divided into three grades: A, B and C.
Class A is suitable for users who are engaged in open fires, sparks, radiation and convection near molten metal.
Class B is suitable for those who are engaged in open flame, spark emission from aramid fabric, inflammable substances and dangerous places of ignition.
Class C is applicable to temporary, non long-term users who have flammable substances and are at risk of fire.
Aramid fabrics are required for fabrics up to grade A, and multi-component aramid, aramid/flame retardant viscose, flame retardant cyanochloride or cotton-based multi-component fiber fabrics are available for grades B and C.
It has permanent flame retardancy, high temperature resistance, high strength, heat radiation protection and good thermal stability. It can be used at high temperature for a long time without aging, melting, shrinking, self-extinguishing, and has good corrosion resistance to general chemicals.
Scope of application:
It is widely used in fire fighting clothes, tank clothes, flying clothes, flame retardant clothes, arc-proof clothes, welding clothes and furnace clothes.
