Standard Method Of Test For Fire And Smoke Characteristics Of Electrical Wiring, Cables And Non-Metallic Raceways

1.1 This test method is for use in determining values of flame propagation distance and smoke optical density for electrical and optical-fibre cables and non-metallic raceways that are to be installed in ducts, plenums, and other spaces used for environmental air. It is not intended for use with cables enclosed in metallic raceways in those spaces. This method also determines values of flame propagation distance and smoke optical density for electrical and optical-fibre cables with combustible jackets or sheathes, and non-metallic raceways to determine their acceptability for use in buildings of non-combustible construction. 1.2 Although this method utilizes similar test apparatus as in CAN/ULC-S102, Standard Method of Test for Surface Burning Characteristics of Building Material and Assemblies, changes have been made to the test furnace such that a test conducted in the apparatus used for this Standard shall not be considered identical or provide comparable results. 1.3 This test method does not cover the construction requirements for cables and non-metallic raceways or their electrical and other performance requirements.
