16 CFR 1610 for Flammability of Clothing Textiles to US

The US Federal flammability standard for general wearing apparel (16 CFR 1610) applies to all apparel textiles. It is particularly important for raised-fiber surface textiles made from cellulosic fibers, as they may be highly susceptible to burning without treatment of flame retardant. Held on a special platform with 45o inclination, specimen with plain or raised surface shall be cut and inserted in a frame for 1-second burning. The time recorded for the flame to travel up a distance of 127mm (5 inches) on the fabric is therefore used for classification.
