1.1 This fire-test-response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side. 1.2 Test Method E84 is a 10-min fire-test response method. The following standards address testing of materials in accordance with test methods that are applications or variations of the test method or apparatus used for Test Method E84: 1.2.1 Materials required by the user to meet an extended 30-min duration tunnel test shall be tested in accordance with Test Method E2768. 1.2.2 Wires and cables for use in air-handling spaces shall be tested in accordance with NFPA 262. 1.2.3 Pneumatic tubing for control systems shall be tested in accordance with UL 1820. 1.2.4 Combustible sprinkler piping shall be tested in accordance with UL 1887. 1.2.5 Optical fiber and communications raceways for use in air handling spaces shall be tested in accordance with UL 2024. 1.3 The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.
