This Standard specifies a test method for the determination of the combustibility of a building material within the criteria given in Clause 3.4.

WARNING: SO THAT SUITABLE PRECAUTIONS ARE TAKEN TO SAFEGUARD HEALTH, THE ATTENTION OF ALL PERSONS CONCERNED IN FIRE TESTS IS DRAWN TO THE POSSIBILITY THAT HARMFUL GASES MAY BE EVOLVED DURING THE COMBUSTION OF TEST SPECIMENS.

Application
‍The test results relate only to the behaviour of the test specimens of the material under the particular conditions of the test, and are not intended to be the sole criteria for assessing the potential fire hazard of the material in use. The test method is not applicable to products which are coated, faced or laminated. In such cases, tests may be carried out separately on the individual materials from which the product is formed and this shall be clearly stated in the test report.

NOTE: The performance of coated, faced or laminated products may be determined by other reaction to fire tests (see Paragraph A1 of Appendix A).

Sets out a test method for determining the combustibility of building materials and is one of a series of test methods for evaluating the potential fire hazard of building products. This fire test was developed for use by those responsible for selection of construction materials which, although not completely inert, produce only a limited amount of heat and flame when exposed to temperatures of approximately 750 degrees Celsius. This revision aligns the test method more closely with ISO 1182:1990 but specifies combustibility criteria necessary for regulatory purposes.
