The early fire behaviour of combustible wall lining materials

摘要

AbstractThe development of the Australian Standard AS 1530 Part 3 ‘Test for Early Fire Hazard Properties of Materials’ from the study of the fire behavior of cellulosic wall linings in simulated room fires has been outlined. Similar studies for assessing a wider range of wall linings are now reported including various plastic facings applied to hardboard. Using similar parameters for ignitability, spread of flame, heat evolved and smoke developed, the behaviors of the linings in the standard test have been compared to the behavior in corner‐wall burns. Two methods of ignition were used for the burns; (a) timber cribs; and (b) impressed radiant heat with a pilot flame. The results are discussed in terms of the validity of the standard test as a multi‐parameter assessment of materials in a fire hazard situation. The test has been validated for the wider range of wall lining ma
