ASTM E 2837 : 2013 : R2017

1.1This 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.

1.2This fire-test-response standard does not measure the performance of the following:

1.3This 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.

1.4The 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.

1.5The 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.

1.6This 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.

1.7Test 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.

1.8Test 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.

1.9This 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.

1.10Potentially important factors and fire characteristics not addressed by this test method include, but are not limited to:

1.11The 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.

1.12The 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.

1.13This 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.

1.14This 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.

1.15Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.16This 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.
