This study investigate heat release rate of cables and wires
used on constructions. The short circuit of cable or wires is
one of the major reasons which cause fires, and injury comes
from high temperatures, high heat fluxes, and large amounts
of toxic gases being emitted. Therefore, the heat release rate
of material pre- sents the parameters of reaction to fire.
The apparatus of heat release rate test are Cone
Calorimeter and Factory Mutual Calorimeter, which are bench-
scale. It based on the principle of oxygen consumption to
measure heat release rate. The testing sample used were
cables and wires according to National stan- dards for
construction. The results showed that the cable of CNS
11359 would not be burned within 20 minutes under the heat
which are 14 kw/m2, the rest of peak of heat release rate
greater than 12.5 kw/m2, which needed for burning of wooden
materials. It could burn the adjoin- ing combustibles .It was
also simultaneously found that the curve of heat release rate
for Cone calorimeter are similar to Factory Mutual
Calorimeter, and the relationship for total heat release
rate between Cone calorimeter and Factory Mutual
Calorimeter are close to linear.
