墙面覆盖物燃烧性能分析阻燃等级防火测试检测机构:
- These methods of fire tests are applicable to doorassemblies, including door frames with lights and panels, ofvarious material and types of construction for use in wall openingsto retard the passage of fire. the method does not provide anevaluation of a swinging door assembly when that assembly as partof a larger assembly(e.g. sliding fire door assembly),or when it isintended to be used as an elevator entrance.
- Tests made in conformity with these test methods areintended to register performance during the test exposure; but suchtests shall not be construed as determining suitability for useafter exposure to fire.
- It is the intent that tests made in conformity with these testmethods allow for the development of data to enable regulatorybodies is determine the suitability of door assemblies for use inlocations where fire resistance of a specified duration isrequired.
- These methods are intended to evaluate the ability of a doorassembly to remain in an opening during a predetermined testexposure.
- The tests expose a specimen to a standard fire exposurecontrolled to achieve specified temperatures throughout a specifiedtime period, followed by the application of a specified standardfire hose stream, the exposure, however is not representative ofall fire conditions , which vary with changes in the amount,nature, and distribution of fire loading , ventilation, compartmentsize and configuration, and heat sink characteristics of thecompartment, it does, however provide a relative measure of fireperformance of door assemblies under these specified fire exposureconditions.

CAN/ULC-S127建筑材料和构件的防火测试-标准名称:
CAN/ULC-S127:standard corner wall method of test forflammability characteristics of Non-melting foam plastic buildingmaterials.
CAN/ULC-S127:墙角法测定非融化泡沫塑料建筑材料的可燃性特性
CAN/ULC-S127建筑材料和构件的防火测试-标准范围:
该可燃性测试方法适用于暴露于火源中不熔化的某些小密度绝缘材料(参考附录A)。它是根据火焰蔓延分类来评估泡沫塑料的可燃性,在建筑材料或构件的表面燃烧特性的测试方法,需要使用计算公式FSV= 92.5 d/t,公式中”d”& “t”为必要参数.
本测试的目的是将材料安装在防火测试用的墙角配置中暴露于火源,确定材料的燃烧特性。
