This standard provides a method for establishing a type test for qualifying the fire performance of penetration fire stops when mounted in fire resistive wall or floor assemblies. This standard also considers the ability of a fire stop to withstand the external force imposed by a hose stream or water spray. Tests conducted in conformance with this standard will establish a time rating for the fire stop. Data developed from the performance of this standard can assist in determining the suitability of a fire stop for use where fire resistance is required. The purpose of this standard is to establish type tests to assure that cable-penetration fire stops meet the required fire rating. The data developed from the use of this standard can assist in determining the suitability of a fire stop for use where fire resistance is required. Revision Standard - Active. The details described in this standard involve developing data to determine a fire stop’s resistance to fire and/or any external force imposed through a hose stream or water spray. The topics are applicable to fire stops of various materials and construction including cable-penetration fire stops which are intended for use in fire-resistive barriers. Tests conducted in conformance with the specifications listed in this standard will record the performance of fire stops during test exposure.
