10、lated at no more than 18.3 m/min(60 ft/min).The lengthof the flame is measured and provides a numerical value for thepropagation of flame along the specimen.5.Significance and Use5.1 This test method is designed to differentiate the flamepropagation characteristics of dense or cellular elastomericco
11、mpounds used in gaskets,setting blocks,shims,or spacers.It is a small scale test which enables the specifier to exerciseengineering judgment in the selection of materials.5.2 In this test method,the specimens are subjected to aspecific laboratory fire test exposure condition.If different testconditi
12、ons are substituted or the anticipated end-use conditionsare changed,it may not be possible by or from this test methodto predict changes in the performance characteristics.Therefore,the results are valid only for the fire test exposurecondition described in this test method.5.3 If the results obtai
13、ned by this test method are to beconsidered in the total assessment of fire risk,then all pertinentestablished criteria for fire risk assessment developed byASTM Committee E-5 must be included in the consideration.6.Apparatus6.1 The Test Chamber,may be any enclosure that willpermit circulation of ai
