Categorization of cable flammability detection of smoldering and flaming cable fires

The purpose of this program for developing detection requirements in cable fires was to investigate the effects of forced ventilation and temperature stratification on the detection of flaming and smoldering fires, and to specify spacing requirements of smoke detectors for flaming cable fires in rooms with flat and beamed ceilings, and in corridors. A simple corridor geometry, common in nuclear reactors, was constructed to study forced ventilation and temperature stratification effects on the detection of smoldering and flaming fires. Criteria for specifying spacing requirements for flaming cable fires were developed for rooms with extensive flat ceilings based on a methodology previously developed at Factory Mutual Research Corporation, and for rooms with beamed ceilings and for corridors based on experimental results in the corridor tests and on a new analysis developed for the present program
