(Test Method)Standard Test Method for Surface Flammability of Flexible Cellular Materials Using A Radiant Heat Energy Source
Standard Test Method for Surface Flammability of Flexible Cellular Materials Using A Radiant Heat Energy Source
SCOPE
1.1 This is a fire test response standard.
1.2 This test method covers the measurement of surface flammability of flexible cellular materials.
1.3 This standard should be used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled 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.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. This test method may involve hazardous materials, operations, and equipment. Specific information about hazards is given in Section 7.
Note 1—There is no similar or equivalent ISO standard.

specimens shall replicate the type and thickness of all the
layers present in the assembly being evaluated.
