1.1 This is a fire-test-response standard.

1.2 This test method covers a small-scale procedure for characterizing the response of a plastic to an ignition source consisting of a small flame of controlled intensity applied to the base of a standard sample being held in a vertical position.

1.3 This standard should be used to measure and describe the reponse 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 in 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 The values stated in SI units are to be regarded as the standard.

Note 1-See Method D3801 which, unless otherwise specified, uses the same specimens for measuring the comparative extinguishing characteristics of solid plastics when tested in a vertical position.

1.5 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. Specific hazard statements are given in 10.1.

Note 2-There is no similar or equivalent ISO standard.
