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.
