Protective clothing - Flame retardant protective
clothing
1 Scope
This Standard specifies the classification, requirements, test methods,
inspection rules, identification, packaging and storage of flame-retardant
protective clothing.
This Standard applies to flame retardant protective clothing that is used in
places where there are open flames, sparks, or where there are flammable
substances and flashover risks.

damaged area. In the damaged area, some areas will produce red heat due to
the continuous release of the previously absorbed heat, and the duration of the
red heat is not included in the afterflow time.

fibers, yarns, and fabrics that do not have or are insufficient in flame retardant
performance.
