ULC-S102.4-M1987 (R1998)

1. Scope 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 that are to be installed in ducts, plenums, and other spaces used for environmental air without the cables being enclosed in 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 to determine their acceptibility for use in buildings of noncombustible construction. 1.2 Althougth this method utilizes the same test apparatus as in the Standard Methods of Test for Surface Burning Characteristics (CAN4-S102M and CAN4-S102.2M), it does not determine surface burning characteristics of electrical wiring and cables. 1.3 This test method does not cover the construction requirements for cables or their electrical and other performance requirements.
