This Standard provides methods for determining the performance of external construction elements when exposed to direct flame impingement from the fire front.NOTES:1 The methods simulate exposure to direct flame impingement from the fire front or large burning items such as other burning buildings or adjacent isolated trees and shrubs by utilizing the Standard heating regime of AS 1530.4.2 Flame contact from the fire front is expected to last less than 2 minutes but a 30 minute exposure period has been nominated to allow for potentially higher transient temperatures from the fire front. The 30 minute exposure also provides resistance to large burning items adjacent to the element of construction.3 The results of the fire tests may be used to directly assess fire hazard, but it should be recognized that a single test method would not provide a full assessment of fire hazard under all fire conditions.4 These fire tests provide data relating to the performance of the particular element and building system and do not provide a general assessment of the performance of a specific type of material for use in bushfire prone areas.
