Significance and Use
5.1 This test method is used to determine the performance of a firestop system with respect to exposure to a standard time-temperature fire test and a hose stream test. The performance of a firestop system is dependent upon the specific assembly of materials tested including the number, type, and size of penetrations and the floors or walls in which it is installed.
5.2 Two ratings shall be established for each firestop system. An F rating shall be based upon flame occurrence on the unexposed surface, while the T rating shall be based upon the temperature rise as well as flame occurrence on the unexposed side of the firestop system. These ratings, together with detailed performance data such as the location of through-openings and temperatures of penetrating items are intended to be one factor in assessing performance of firestop systems.
1.1 This test method is applicable to firestop systems of various materials and construction. Firestop systems are intended for use in openings in fire-resistive walls and floors that are evaluated in accordance with Test Methods E119.
1.2 Tests conducted in conformance with this test method record firestop system performance during the test exposure; but such tests shall not be construed to determine suitability of the firestop system for use after test exposure.
1.3 This test method also measures the resistance of firestop systems to an external force stimulated by a hose stream. However, this test method shall not be construed as determining the performance of the firestop system during actual fire conditions when subjected to forces such as failure of cable support systems and falling debris.
1.4 The intent of this test method is to develop data to assist others in determining the suitability of the firestops for use where fire resistance is required.
1.5 This test method does not apply to membrane penetrations of a floor-ceiling assembly or roof-ceiling assembly that are tested as part of the assembly in accordance with Test Methods E119.
1.6 This test method does not apply to membrane penetrations of load-bearing walls.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of materials, products, or assemblies under actual fire conditions.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.10 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard.
