NFPA 701

NFPA 701
NFPA 701-1989 compared with NFPA 701-1999 Whether it is 701-1989 or 701-1999, the purpose of the test is to evaluate the textile and film products, when exposed to the fire source, the flame transmission situation. But the two in its scope of application, the biggest difference is that 701-1989 is not suitable for testing multi-layer cloth or combination cloth only on the fire test method NFPA 701-1989 and NFPA 701-1999. The test range of test conditions, sample size and qualified to determine the standard for a simple induction comparison of a test range
NFPA701-1989: This test method is widely used to assess the fire resistance of fireproof materials such as building materials, a few designated protective clothing or outdoor shelters such as canvas, tent and the like. It is also used to evaluate the fire resistance of the plastic film products inside the building, which is not suitable for multi-layer cloth or cloth. The same time as
