AbstractThe testing of carpets and vinyl roll flooring for flame spread rate and smoke evolution in the 25-foot tunnel furnace in the manner specified by ASTM E84 is neither realistic nor convenient. By modifying the furnace and the procedure to permit testing on the foor instead of on the ceiling, more meaningful results are obtained at reduced cost of materials and in less time. The results of testing a wide variety of carpets in both modes of mounting, with and without undercushioning, emphasize the differences in behaviour of the more important natural and synthetic fibres and blends. The apparent advantages of testing on the floor of the furnace were sufficient to justify the incorporation of this method in a new standard (CSA B54.9-1972), which is invoked in the control of floor covering hazards in certain areas of high-rise buildings in recent revisions of the National Building Code of Canada.
