|Significance and Use|
5.1 This horizontal flame test method measures the ability of the material to cease flaming when the source of ignition used is removed.
5.2 This test method also provides a measure of the capability of the material to spread flame by dripping of flaming particles.
5.3 This test method is used to assess the horizontal flame test performance of electrical insulation materials in Test Methods .
5.4 In this test method, the test specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. The results are therefore valid only for the fire-test-exposure conditions described in this test method.
1.1 This is a fire-test-response standard.
1.2 This fire test method is applicable to the electrical insulation materials contained in wires or cables.
1.3 The ignition source is a gas burner fueled by methane or natural gas.
1.4 Use the values stated in SI units in referee decisions; see IEEE/ASTM SI-10. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.5 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.
1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
