IEEE 634:2004 (R2010)

Revision Standard - Inactive-Reserved.
Revision of IEEE Std 634-1978 This standard is applicable to fire stops of various materials and construction. Cablepenetration fire stops are intended for use in fire-resistive barriers. Tests conducted in conformance with this standard will record the performance of fire stops during the test exposure. The resistance of a fire stop to an external force imposed by a hose stream or water spray will also be considered in this standard. The intent of this standard is to develop data to assist in determining the suitability of a fire stop for use where fire resistance is required.

This standard provides direction for establishing a type test for qualifying the fire performance of penetration fire stops when mounted in fire resistive wall and floor assemblies. Update the standard with addition of positive pressure testing, method for criteria, and add appendix for usage of test.
The purpose of this standard is to establish a type test to assure that penetration fire stop assemblies meet the requirements to obtain a fire rating by passing a standardized fire test under laboratory conditions. The requirements include the principles and procedures for testing.
