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.
