I. INTRODUCTION
This report describes the results of the ASTM E84 TEST FOR SURFACE BURNING
CHARACTERISTICS OF BUILDING MATERIALS a method for determining the
comparative surface burning behavior of building materials. This test is applicable to
exposed surfaces, such as ceilings or walls, provided that the material or assembly of
materials, by its own structural quality or the manner in which it is tested and intended
for use, is capable of supporting itself in position or being supported during the test
period.
The purpose of the method is to determine the relative burning behavior of the
material by observing the flame spread along the specimen. Flame spread and
smoke density developed are reported, however, there is not necessarily a
relationship between these two measurements.
“The use of supporting materials on the underside of the test specimen may lower the
flame spread index from that which might be obtained if the specimen could be tested
without such support... This method may not be appropriate for obtaining comparative
surface burning behavior of some cellular plastic materials... Testing of materials that
melt, drip, or delaminate to such a degree that the continuity of the flame front is de-
stroyed, results in low flame spread indices that do not relate directly to indices ob-
tained by testing materials that remain in place.”
This test method is also published under the following designations:
NFPA 255
UL 723
UBC 8-1
This standard should be used to measure and describe the properties of
materials, products, or assemblies in response to heat and flame under
controlled laboratory conditions and should not be used to describe or
appraise the fire hazard or fire risk of materials, products, or assemblies
under actual fire conditions. However, results of this test may be used as
elements of a fire risk assessment which takes into account all of the
factors which are pertinent to an assessment of the fire hazard of a par-
ticular end use.
