Large-scale fire test of ETFE film roofing material

Abstract

Abstract: In this paper, a large-scale fire test of ETFE film was designed, the combustion characteristics of ETFE film under a fire with a heat release rate of 4 MW were studied, and whether the ETFE film burns with droplets under standard test and largescale fire test conditions was discussed. The results showed that with the heat release rate of 4 MW, the ETFE film where the flame can reach has softened, burned through and dripped, and where the flame can't reach has maintained integrity. The ETFE film that meets the B1 (d0) level requirements specified in GB 8624-2012 is likely to show droplets in actual fires, and whether ETFE film will drip in actual fires shall not only depend on the results of standard tests. Whether the burning of ETFE film will cause droplets is related to the size of the film, installation method and fire conditions, etc.

Key words: ETFE film, roofing material, fire test, droplet
