Designation: E84-01 Standard Test Method for Surface Burning Characteristics of Building Materials11. Scope1.1This fire-test-response standard for the comparativesurface burning behavior of building materials is applicable toexposed surfaces such as walls and ceilings. The test isconducted with the specimen in the ceiling position with thesurface to be evaluated exposed face down to the ignitionsource. The material. product, or assembly shall be capablc ofbeing mounted in the test position during the test.Thus,thespecimen shall either be self-supporting by its own structuralquality, held in place by added supports along the test surfacc,or secured from the back side.1.2 The purpose of this test method is to determine thcrelative burning behavior of the material by observing theflame spread along the spccimen. Flame spread and smokedeveloped index are reported. However. there is not necessarilya relationship between these two measurements.1.3 The use of supporting materials on the underside of thetest specimen has the ability to lower the flame spread indexfrom those which might be obtained if the specimen could belested without such support. These test results do not neces-sarily r
