Molten Dripping: Yes. Odor of Smoke: Yes. Conclusion: The sample meets the requirements of NFPA 701:2015 Test Method 1. Both in its original condition and after 25 washing cycles, the fabric exhibited no after flame time, and the mass loss was within acceptable limits (below 6.07% before washing, and below 6.15% after washing). The fabric passed the flame resistance test.
