Standard Test Method for Determining the Fire Resistance of Continuity Head-of-Wall Joint Systems Installed Between Rated Wall Assemblies and Nonrated Horizontal Assemblies
 N E2837

Annotation

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.

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

The rated wall assembly, which is already established by other test methods, such as Test Method E119, or

The nonrated horizontal assembly, which would be established by other test methods such as Test Method E119.

NOTE 1—Typically, rated wall assemblies obtain a fire resistance rating after being tested to Test Method E119, NFPA 251, UL 263, CAN/ULCS101, or other similar fire resistive test methods.

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.

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.

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.

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.
