3、all continuity is required by various model codes at joint openings, which are linear voids, gaps,openings, or other discontinuities between or bounded by a rated wall assembly and nonratedhorizontal assemblies, to ensure that the protected joint opening has the same fire resistance rating asthe rat

4、ed wall assembly. The joint opening at the termination at the top of the rated wall assemblybelow the nonrated horizontal assembly must be protected by a continuity head-of-wall joint system,which has a fire resistance rating, in order to maintain continuity established by the rated wallassembly. Th

5、is test method is not required when the rated wall assembly contacts nonrated horizontalassemblies when there is no joint opening. Normally such joint openings are denoted as “linear”because the length is normally greater than their width, which is defined by a typical ratio of at least10:1 as in pr

6、actice. Joint openings are present in buildings as a result of: (1) Design to accommodatevarious movements induced by thermal differentials, seismicity, and wind loads and exists as aclearance separation. (2) Acceptable dimensional tolerances between two or more building elements,for example, betwee

7、n non-loadbearing walls and roofs. (3) Inadequate design, inaccurate assembly,repairs or damage to the building. There are many unique applications for joint systems in buildings.To address this issue there are different types of continuity head-of-wall joint systems. It is not possibleto test all f

8、ire-resistive joints systems using the same test apparatus or method of test, for example,TestMethod E2307 employs the ISMAtest apparatus.Acontinuity head-of-wall joint system is a particulartype of fire-resistive joint system that provides fire resistance to prevent passage of fire fromcompartment

9、to compartment within the building at the joint opening between a rated wall assemblyand a nonrated horizontal assembly. A continuity head-of-wall joint system is a unique buildingconstruction detail not addressed by other fire test methods such as Test Method E1966 that tests jointsystems installed

10、 between two assemblies that are fire resistance rated.1. Scope1.1 This fire-test-response test method measures the performance of a unique fire resistive joint system called a continuityhead-of-wall joint system, which is designed to be used between a rated wall assembly and a nonrated horizontal a

11、ssembly duringa fire resistance test.1.2 This fire-test-response standard does not measure the performance of the following:1.2.1 The rated wall assembly, which is already established by other test methods, such as Test Method E119, or1.2.2 The nonrated horizontal assembly, which would be establishe

12、d by other test methods such as Test Method E119.NOTE 1Typically, rated wall assemblies obtain a fire resistance rating after being tested to Test Method E119, NFPA 251, UL 263, CAN/ULC-S101,or other similar fire resistive test methods.1.3 This fire-test-response standard is not intended to evaluate

13、 the connections between rated wall assemblies and nonratedhorizontal 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 thecontinuity head-of-wall joint system

14、is subjected to one of two time-temperature fire exposures.1 This test method is under the jurisdiction of ASTM Committee E05 on Fire Standards and is the direct responsibility of Subcommittee E05.11 on Fire Resistance.Current edition approved Dec. 1, 2011July 15, 2013.

However, it requires that such phenomena be documented and reported when describi

22、ntinuity 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

These notes and footnotes(excluding those in tables and figures) shall not

It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicab
