1.1 This fire-test-response test method measures the performance of a unique fire resistive joint system called a continuity head-of-wall joint system , which is designed to be used between a rated wall assembly and a nonrated horizontal assembly during a fire resistance test. 1.2 This fire-test-response standard does not measure the performance of the rated wall assembly or the nonrated horizontal assembly . Note 1: Typically, rated wall assemblies obtain a fire resistance rating after being tested to Test Method E119 , UL 263, CAN/ULC-S101, or other similar fire resistance test methods. 1.3 This fire-test-response standard is not intended to evaluate the connections between rated wall assemblies and nonrated horizontal assemblies unless part of the continuity head-of-wall joint system. 1.4 The fire resistive test end point is the period of time elapsing before the first performance criteria is reached when the continuity head-of-wall joint system is subjected to one of two time-temperature fire exposures. 1.5 The fire exposure conditions used are either those specified by Test Method E119 for testing assemblies to standard time-temperature exposures or Test Method E1529 for testing assemblies to rapid-temperature rise fires. 1.6 This test method specifies the heating conditions, methods of test, and criteria to establish a fire resistance rating only for a continuity head-of-wall joint system . 1.7 Test results establish the performance of continuity head-of-wall joint systems to maintain continuity of fire resistance of the rated wall assembly where the continuity head-of-wall joint system interfaces with a nonrated horizontal assembly during the fire-exposure period. 1.8 Test results shall not be construed as having determined the continuity head-of-wall joint system , nonrated horizontal assembly and the rated wall assembly’s suitability for use after that fire exposure. 1.9 This test method does not provide quantitative information about the continuity head-of-wall joint system relative to the rate of leakage of smoke or gases or both. However, it requires that such phenomena be documented and reported when describing the general behavior of continuity head-of-wall joint systems during the fire resistive test but is not part of the conditions of compliance. 1.10 Potentially important factors and fire characteristics not addressed by this test method include, but are not limited to: 1.10.1 The performance of the continuity head-of-wall joint system constructed with components other than those tested. 1.10.2 The cyclic movement capabilities of continuity head-of-wall joint systems other than the cycling conditions tested. 1.11 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. 1.12 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 as requirements of the standard. 1.13 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 the materials, products, or assemblies under actual fire conditions. 1.14 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.15 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.16 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method evaluates the following under the specified test conditions: 5.1.1 The ability of a test specimen to undergo movement without reducing its fire resistance rating, and 5.1.2 The duration for which a test specimen will contain a fire and retain its integrity during a predetermined fire resistive test exposure. 5.2 This test method provides for the following measurements and evaluations where applicable: 5.2.1 Ability of the test specimen to movement cycle . 5.2.2 Ability of the test specimen to prohibit the passage of flames and hot gases. 5.2.3 Transmission of heat through the test specimen . 5.2.4 Ability of the test specimen to resist the passage of water during a hose stream test. 5.3 This test method does not provide the following: 5.3.1 Any information about the rated wall assembly because its performance has already been determined. 5.3.2 Evaluation of the degree by which the test specimen contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion. 5.3.3 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the test specimen . 5.3.4 Measurement of flame spread over the surface of the test specimen . Note 3: The information in 5.3.1 – 5.3.4 may be determined by other suitable fire resistive test methods. For example, 5.3.4 may be determined by Test Method E84 . 5.4 In this procedure, the test specimens are subjected to one or more specific tests under laboratory conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured. Therefore, the results are valid only for the exposure conditions described in this test method.
