1.1This fire-test-response standard provides a means of measuring mass loss and ignitability, for screening purposes, from essentially planar materials, products, or assemblies (including surface finishes), exposed to controlled levels of radiant heating, with or without an external ignitor. This test method is intended for screening purposes only.
1.2The principal fire-test-response characteristics obtained from this test method are those associated with mass loss from the specimens tested, as a function of time. Time to sustained flaming is also determined. Heat release is, optionally, determined using thermopile measurements detailed in Annex A2.
1.2.1The fire-test-response characteristics obtained from this test are best used for comparisons between materials with some similarities in composition or structure.
1.3The relationship between mass loss and heat release depends on the material, product, or assembly tested, and no universal formula exists for calculation of heat release using mass loss measurements (see also additional limitations in 5.7).
1.4The fire-test-response characteristics obtained from this test method are also obtainable with the apparatus used in Test Method E1354 (the cone calorimeter) or in an applications standards of that equipment (see also 5.4). The referenced test methods permit measurements of added fire-test-response characteristics.
1.5The fire-test-response characteristics obtained by this test method are specific to the specimen tested, in the form and thickness tested, and are not an inherent property of the material, product, or assembly.
1.6This fire-test-response method does not provide information on the fire performance of the test specimens under fire conditions other than those conditions specified in this test method. For additional limitations of this test method, see 5.7.
1.7Use the SI system of units in referee decisions; see IEEE/ASTM SI-10. The units given in parentheses are for information only.
1.8This 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.
1.9Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. See also Section 7.
1.10This 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.
1.11This 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.
