阐述了测定建筑材料燃烧性的试验方法，是评估建筑产品潜在火灾危险的一系列试验方法之一。该耐火试验是为负责选择建筑材料的人员开发的，这些材料虽然不是完全惰性的，但在暴露于约750摄氏度的温度时，仅产生有限的热量和火焰。本次修订使试验方法更符合ISO 1182:1990，但规定了监管目的所需的燃烧性标准。

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.
