This method of test is applicable to firestop systems with or without penetrating items, such as cables, cable trays, conduits, ducts and pipes. These firestop systems are intended for use in openings in fire resistive wall and floor assemblies and membranes forming part of an assembly required to have a fire resistance rating and linear openings between adjacent fire resistive floor assemblies, wall assemblies or both.

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.

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.

Provisions are included to allow for testing with a pressure differential between the furnace chamber and the exterior.

Provisions are included to allow for optional air leakage testing to determine the air leakage rate through test specimens resulting from a specified air pressure difference applied across the surface of the test specimens. The results of this test are intended to develop data to assist in determining the acceptability of firestop systems with reference to the control of air movement.

The testing of This test method is not applicable to a joint firestop system placed into a perimeter joint located between a fire rated floor and a non fire rated exterior wall is not intended to be tested using this test method.
