GB/T 8627-2007 in English

《GB/T 8627-2007建筑材料燃烧或分解的烟密度试验方法》由TC113（全国消防标准化技术委员会）归口，TC113SC7（全国消防标准化技术委员会防火材料分会）执行，主管部门为应急管理部。
本标准规定了建筑材料燃烧或分解的烟密度试验装置、试验步骤和试验结果的计算及试验报告的具体要求。
本标准规定了测量建筑材料在燃烧或分解的试验条件下的静态产烟量的试验方法。本试验方法是在标准试验条件下，通过测试试验烟箱中光通量的损失来进行烟密度测试。本试验设备可以在试验期间观察到火焰和烟气等现象。

1 Scope

This Standard specifies specific requirements on the test apparatus, test procedure for smoke density from the burning or decomposition of building materials, test results calculation and test report.
This Standard specifies test method for measuring the relative amounts of smoke obscuration produced by the burning or decomposition of building materials. It is intended to be used for measuring the smoke-producing characteristics of building materials under controlled conditions of combustion or decomposition. The measurements are made in terms of the loss of light transmission through a collected volume of smoke produced under controlled, standardized conditions. The apparatus is constructed so that the flame and smoke can be observed during the test.
This standard should be used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire-hazard or fire-risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire-hazard assessment or a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard or fire-risk of a particular end use.
