1.1This test method covers a procedure for measuring the critical radiant flux of exposed attic floor insulation subjected to a flaming ignition source in a graded radiant heat energy environment inside a test chamber. The test specimen can be any attic floor insulation. This test method is not applicable to those insulations that melt or shrink away when exposed to the radiant heat energy environment or the ignition source.
1.2This test method measures the critical radiant flux at the farthest point to which the flame advances. It provides a means for relative classification of a fire test response standard for exposed attic floor insulation. The imposed radiant flux simulation levels of thermal radiation are likely to impinge on the surface of exposed attic insulation from roof assemblies heated by the sun and by heat or flames of an incidental fire which has the potential to involve an attic space. This test method is intended to simulate an important element of fire exposure that has the potential to develop in open attics, but is not intended for use in describing flame spread behavior of insulation installed other than on an attic floor.
1.3The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4This 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 material, products, or assemblies under actual fire conditions.
1.5Warning—Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
