Scope

This Standard specifies the specific requirements for the test apparatus, test procedure,
calculation of test results and test report for density of smoke from the density or
decomposition of building materials.
This Standard specifies the test method for the measurement of volume of smoke
produced under controlled conditions of combustion or decomposition. The
measurements with this test method 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 is observable
during the test.
This standard is used to measure and describe the response of materials, products, or
assemblies to heat and flame under controlled conditions, but does not by itself
incorporate all factors required for fire hazard or fire risk assessment of the materials,
products, or assemblies under actual fire conditions.

Summary	This standard specifies the smoke density test device supplies the combustion or decomposition, specific requirements of the test procedures and test results of the calculation and the test report. This standard specifies test methods for measuring static supplies the amount of smoke in the combustion or decomposition of the test conditions. This test method is under standard test conditions, test trials by the loss of the smoke chamber flux for smoke density test. The test equipment can be observed phenomenon of flame and smoke during the test. This standard is used to measure and describe the laboratory under controlled conditions in the material, article, assembly in response to heat and flame, but can not be used to describe and evaluate materials, articles or components of fire in a real fire and toxic conditions dangerous. When taking into account the specific end use to say when all factors related to risk assessment, the results of the test can be used as a parameter fire risk assessment.
