1、Designation: E84 15b An American National StandardStandard Test Method forSurface Burning Characteristics of Building Materials1This standard is issued under the fixed designation E84; the number immediately following the designation indicates the year of originaladoption or, in the case of revision
2、, the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This fire-testresponse
3、 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 a
4、ssembly shall be capable 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 surface,or secured from the back side.1.2 The purpose of this test method is to determine ther
5、elative burning behavior of the material by observing theflame spread along the specimen. 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 th
6、e ability to lower the flame spread indexfrom those which might be obtained if the specimen could betested without such support. These test results do not neces-sarily relate to indices obtained by testing materials withoutsuch support.1.4 Testing of materials that melt, drip, or delaminate tosuch a
7、 degree that the continuity of the flame front is destroyed,results in low flame spread indices that do not relate directly toindices obtained by testing materials that remain in place.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathem
8、aticalconversions to SI units that are provided for information onlyand are not considered standard.1.6 The text of this standard references notes and footnotesthat provide explanatory information. These notes andfootnotes, excluding those in tables and figures, shall not beconsidered as requirement
9、s of the standard.1.7 This standard is used to measure and describe theresponse of materials, products, or assemblies to heat andflame under controlled conditions, but does not by itselfincorporate all factors required for fire-hazard or fire-riskassessment of the materials, products, or assemblies
10、underactual fire conditions.1.8 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations
11、prior to use.1.9 Fire testing is inherently hazardous. Adequate safe-guards for personnel and property shall be employed inconducting these tests.2.
