CAN ULC-S102.4-2010：電線電纜的燃燒及煙霧特征防火測試方法

CAN ULC-S102.4 Abstract 摘要
CAN ULC-S102.4 This test is designed to provide information for evaluating the possibilityof fire spreading in a plenum or other space used for environmental air alongelectrical wires or cables, optical-fiber cables or non-metallic raceways; orthe possibility of high smoke levels being developed in the space when wiringor raceways are subject to fire exposure. The test method has been related tothe results of tests on cables exposed to fires in simulated plenums.

CAN ULC-S102.4 This test method is used to determine if a cable or non-metallic racewayqualifies for an FT-6
classification as specified in CSA C22.2 No. 0.3, Test Methods for ElectricalWires and Cables or CSA C22.2 No. 262, Optical Fiber Cable and CommunicationCable Raceway Systems.

CAN ULC-S102.4 This test method is for use in determining values of flame propagationdistance and smoke optical density for electrical and optical-fiber cables andnon-metallic raceways that are to be installed in ducts, plenums, and otherspaces used for environmental air. It is not intended for use with cablesenclosed in metallic raceways in those spaces. This method also determinesvalues of flame propagation distance and smoke optical density for electricaland optical-fiber cables with combustible jackets or sheathes, and non-metallicraceways to determine their acceptability for use in buildings of non-combustibleconstruction.

CAN ULC-S102.4 This test method does not cover the construction requirements for cablesand non-metallic raceways or their electrical and other performancerequirements.
