Abstract : The National Electrical Code requires that riser cables have sufficient fire resistance so they will not spread fire from floor to floor in a shaft. Fire tests were conducted as the initial task in developing a test method for determining compliance with the Code. The tests provided data on the flame propagation characteristics of riser cables in a simulated riser shaft, the design of which was based on information from a field survey. The data indicated that with a large ignition source, simulating burning combustibles in a shaft without fire stops, some cables propagated fire from floor to floor; others, utilizing newer fire resistive materials, did not exhibit the same propensity to promulgate fire.
