Abstract

A test procedure employing the TRI Flammability Analyzer has been developed for measuring the combustion pro pensity of carpets. The method evaluates the Limiting Oxygen Index (LOI), rate of flame propagation, and smoke development characteristics of carpet samples undergoing horizontal-type burning. A variety of mounting arrange ments and ignition sources were initially investigated and a test procedure employing three methenamine-timed burning tablets as the ignition source was established. Test results are reported for 20 carpets combining different pile fibers, construction and backing materials. General conclusions regarding the effects of these parameters are discussed. Possible test criteria based on the values for the LOI, used in conjunction with the burning rates and smoke produced, are suggested for assessing the suitability of a particular carpet for specific uses.
