NFPA 701: Standard Methods of Fire Tests for Flame Propagation of Textiles and F

 

The NFPA 701 standard test method involves brief exposure of textiles and films to a small flame. The primary purpose of the test is to evaluate the combustion characteristics of the material when exposed to an ignition source, primarily its time to ignition, rate of burning, and degree of flame propagation.

 

Based on the test results, materials can be categorized into one of the following three classes in accordance with NFPA 701:

 

1. NFPA 701: A material that passes the test without self-sustaining combustion and without flame propagation to locations of the material away from the source of ignition.

2. NFPA 701-1: Passes the test, but minor drips are produced during the test.

3. NFPA-701-2: Fails the test with rapid flame propagation or excessive burning time.

 

The scope of application of the NFPA 701 standard includes textiles and film materials for use in public places, theaters, hotels, medical facilities, schools, and other buildings that are required to meet fire protection requirements.

 

Please note that as part of the standard, NFPA 701 may be updated and revised over time. For specific application requirements, please refer to the latest edition of the standard or consult your local agency for accurate information.
