Abstract:

U. S. and Canadian reaction-to-fire tests for wire and cable are examined. The technical basis for their development is analyzed. The data requirements for engineering computations of fire hazard are examined. It is found that the current methods are primarily based on determining ignitability, speed of flame travel, or distance of flame propagation. The fire hazard to building occupants, however, is associated with the heat release rate of the fire, instead. Newer testing methods, which are not yet standards but which do measure the heat release rate of cables, are already under development. A limited comparison is made to British and international standards. Recommendations are made for improved testing strategies. The document includes about 300 reference.
