S115-95 (R2001)

1. Scope 1.1 This method of test is applicable to firestop systems incorporating through penetrations or poke-through termination devices as well as to firestops alone (material with no penetrations). These firestop systems are intended for use in openings in wall and floor assemblies required to have a fire resistance rating as established in CAN/ULC-S101M, Standard Methods of Fire Endurance Tests of Building Construction and Materials. 1.2 Tests conducted in conformance with this method will record firestop performance during the fire-test exposure under laboratory conditions; but such tests shall not be construed as determining suitability of the firestop system for use after exposure to fire. 1.3 The test method allows for the testing of the resistance of firestop systems to an external force simulated by a hose stream. However, this method shall not be construed as determining the performance of the firestop during actual fire conditions when subjected to forces such as failure of cable support systems and falling debris. 1.4 Provisions are included to allow for testing with a pressure differential between the furnace chamber and the exterior. 1.5 It is the intent that tests made in conformity with these test methods will develop data to enable regulatory bodies to determine the suitability of firestop systems for use in assemblies where fire resistance of a specified duration is required. 1.6 Provisions are included to allow for optional air leakage testing to determine the rate of air leakage through test samples resulting from a specified air pressure difference applied across the surface of the test samples. The results of this test are intended to develop data to assist regulatory bodies and others in determining the acceptability of firestop systems with reference to the control of air movement through the assembly. NOTE: Tests for air leakage are performed under laboratory conditions. In actual usage, results may vary because of installation and/or environmental conditions. See Appendix A6. 1.7 For the purpose of this Standard, a firestop system refers to a specific construction consisting of: A Any device intended to close off an opening or penetration during a fire; and/or B Material(s) that fill an opening in a wall or floor assembly where penetration is by cables, cable trays, conduits, ducts and pipes and any poke-through termination devices, such as electrical outlet boxes along with their means of support through the wall or floor opening.
