NFPA 701 Standard Fire Test Method for Flame Spread of Textiles and Films

Textiles and fabrics are widely used in public places and indoors, so their flame retardant properties are attracting more and more public attention. Textiles and fabrics with good flame retardant properties can greatly reduce the incidence of fire. When the fire occurs, the flame retardant properties of textiles and fabrics can also play an important role, they do not burn quickly, they delay the flame when the fire occurs.

NFPA 701 Standard Fire Test Method for Flame Spread of Textiles and Films

NFPA 701 Test Method 1

It shall apply to materials with an areal density equal to or less than 700 g/m2, including fabrics or other materials used in curtains, drapery or other window treatments. It is applied to fabrics with an area density less than or equal to 700 g/m2 and used in other construction applications where the layers are attached together by sewing or other means.

NFPA 701 Test Method 2

It is applied to decorative materials other than lined curtains, plastic films, fabrics using vinyl-coated fabric blackout liners or vinyl-coated fabric blackout liners.

The purpose of Test Methods 1 and 2 will be to assess the spread of flame beyond the area exposed to the ignition source. Test Methods 1 and 2 are performed to show whether the material being tested resists the spread of flame under conditions of more severe fire exposure or when the material is used in a different way from the test conditions.

Fabrics used in most public areas are required by law in many states and cities to be certified flame retardant, according to standards developed by the National Fire Protection Association (NFPA). The NFPA has various standards depending on how the fabric will be used. The standard applicable to curtains, curtains and similar hanging textiles is NFPA 701. The NFPA 701 (Small Scale) test measures the ignition resistance of a fabric after 12 seconds of exposure to flame. Flame, coal length and flame residue are recorded. The fabric will pass the test if all samples have a final flame of less than 2,0 seconds, a character length of less than 6,5, the sample does not continue to ignite after reaching the bottom of the test chamber, and meets the criteria.
