Review on four standard tests on flame spreading

Four flame spread tests on materials and components were surveyed in this paper. They are ASTM E1321-97a, BS476: Part 7: 1997, ASTM E84-99/NFPA 255 and ISO 9705: 1993(E). The scale of these tests, the heat sources concerned, testing requirements, environment, experimental setups, results and classification systems were reviewed. Selected results on materials assessed by the four tests using data reported in the literature are illustrated. Preliminary studies indicated that ISO 9705: 1993(E) is a test suitable for assessing flame spreading of materials and components.Department of Building Services Engineerin
