Jan 1, 2019 · Test Method 1 shall apply to materials with an areal density less than or equal to 700 g/m 2 (21 oz/yd 2), including the following: (1) Fabrics or other materials used in curtains, draperies, or other window treatments. (2) Single-layer fabrics.

What is the NFPA 701 Test? Fabrics used in most public spaces (including schools, churches, auditoriums, theatres, and more.) is required by law in many states and cities to be certified as flame retardant, according to standards developed by …

How to run a NFPA 701 field test: 1. Treat fabric with Flamecheck™ M-111. Allow to dry. 2. Cut a fabric sample (1” x 6”) from the item to be tested. 3. Attach to a wire coat hanger or use metal tongs to hold the sample away from your fingers. Make sure you conduct this test over a sink or somewhere safe, not near combustible materials. 4.

What Is the NFPA 701 Test? The NFPA 701 test involves mounting a fabric sample in a controlled test chamber with an open flame. After exposing the fabric to the open flame for a certain period, we assess the char length, which is the length of damage caused by a flame moving upward.

NFPA 701 tests methods, which assess the flame resistance and flame propagation characteristics of textiles and films used in or outside public occupancy buildings.

NFPA 701 is the most standard methods of fire tests for flame propagation of textiles and films. This test has two test methods based on fabric density. NFPA 701 test method 1 is a small scale test that addresses materials with an areal density less than or equal to 21 oz/yd2.

What is the NFPA 701 test? Under NFPA 701, drapery fabric is tested by burning a small sample and measuring the flame, char length and flaming residue. If a fabric meets the NFPA 701 standards in these three areas, the fabric is considered flame retardant and receives a …

Test Method 1 shall apply to materials with an areal density less than or equal to 700 g/m2 (21 oz/yd2), including the following: (1) Fabrics or other materials used in curtains, draperies, or other window treatments (2) Single-layer fabrics (3) Multilayer curtain and drapery assemblies in which the layers are fastened together by sewing or ...

NFPA 701 is looking at the propagation of flames beyond the area exposed to the ignition source. A distinction to recognize is that this test is not determining if the item is flame proof, but merely how well the flames will propagate.

NFPA 701 establishes the testing standard, which assesses flame propagation for textiles and film, including curtains, table linings, textile hangings, tents, tarps, and plastic sheeting. If a fabric is certified as fire-retardant, then it has passed the NFPA 701 test.
