AbstractA positive pressure fire test was carried out on two small- scale 6 in. thick, high-temperature concrete walls penetrated by 13 multi-core and 6 coaxial telephone cables. Alumina-silica-ceramic bulk fibre, capped at the exterior face with cementitious sealant, constituted the firestopping around the cables. The penetrations proved satisfactory except for those involving the two largest cables, which gave unacceptably high temperatures after approximately 2 hr of test. Sealing the ends of the cables could have further improved performance.
