本建筑材料表面燃烧特性试验方法适用于任何类型的建筑材料，根据其自身的结构质量或使用方式，能够将其自身支撑到位，或可在本标准所述的试验炉中支撑，或以与其推荐用途相当的方式支撑。如果无法轻易确定材料为热塑性或热固性材料，则根据本标准进行一次试验，并根据CAN/ULC-S102的要求进行一次附加试验。2.地板、地板覆盖物及其他材料和组件表面燃烧特性的标准试验方法。本试验的主要目的是通过评估暴露于试验火焰时火焰在其表面上的传播，确定受试材料或组件的比较燃烧特性，从而建立一个可以比较不同材料或组件表面燃烧特性的基础，没有具体考虑可能影响这些特性的所有最终用途参数。 本方法的目的是记录暴露期间的性能，而不是确定试验暴露后的适用性。

This method of test for surface burning characteristics of building materials is applicable to any type of building material that, by its own structural qualities or the manner in which it is applied, is capable of supporting itself in position or may be supported in the test furnace as described in this Standard or in a manner comparable to its recommended use.Where a material cannot be readily determined to be thermoplastic or thermoset, one test is conducted in accordance with this Standard and one additional test in conformance with requirements of CAN/ULC-S102.2, Standard Method of Test for Surface Burning Characteristics of Flooring, Floor Coverings, and Miscellaneous Materials and Assemblies.The primary purpose of this test is to determine the comparative burning characteristics of the material or assembly under test by evaluating the flame spread over its surface when exposed to a test fire and thus establish a basis on which surface burning characteristics of different materials or assemblies may be compared, without specific considerations of all the end use parameters that might affect these characteristics.It is the intent of this method to register performance during the period of exposure, and not to determine suitability for use after the test exposure.
