3、imeter fire barrier system” throughout in September 2004.INTRODUCTIONA perimeter fire barrier is the perimeter joint protection that provides fire resistance to preventpassage of fire from floor to floor within the building at the opening between the exterior wallassembly and the floor assembly. A p
4、erimeter fire barrier is a unique building construction detail notaddressed by other fire test methods.Among its other functions, a perimeter fire barrier impedes the vertical spread of fire from the floorof origin to the floor(s) above, at the buildings exterior perimeter and accommodates variousmo
5、vements such as those induced by thermal differentials, seismicity, and wind loads.This test method describes criteria and test methods used to determine the fire resistance ofperimeter fire barriers when subjected to standard fire exposure conditions using the intermediate-scale, multistory test ap
6、paratus (ISMA). The use of the multi-story test apparatus and this test methodare intended to simulate a possible fire exposure on a perimeter fire barrier.1. Scope1.1 This test method measures the performance of theperimeter fire barrier and its ability to maintain a seal toprevent fire spread duri
7、ng the deflection and deformation of theexterior wall assembly and floor assembly during the fire test,while resisting fire exposure from an interior compartment fireas well as from the flame plume emitted from the windowburner below. The end point of the fire resistance test is theperiod of time el
8、apsing before the first condition of complianceis reached as the perimeter fire barrier is subjected to atime-temperature fire exposure.1.2 The fire exposure conditions used are those specified bythis test method for the first 30 min of exposure and thenconform to the Test Methods E119time-temperatu
9、re curve forthe remainder of the test in the test room.1.3 This test method specifies the heating conditions, meth-ods of test, and criteria for evaluation of the ability of aperimeter fire barrier to maintain the fire resistance where afloor and exterior wall assembly are juxtaposed to a perimeterj
10、oint.1.4 Test results establish the performance of perimeter firebarriers during the fire-exposure period and shall not beconstrued as having determined the suitability of perimeter firebarriers for use after that exposure.1.5 This test method does not provide quantitative informa-tion about the per
11、imeter fire barrier relative to the rate ofleakage of smoke or gases or both. While it requires that suchphenomena be noted and reported when describing the generalbehavior of perimeter fire barrier during the fire resistance test,such phenomena are not part of the conditions of compliance.1.6 Poten
12、tially important factors and fire characteristics notaddressed by this test method include, but are not limited to:1.6.1 The performance of the perimeter fire barrier con-structed with components other than those tested, and1.6.2 The cyclic movement capabilities of perimeter firebarriers other than
13、the cycling conditions tested.1.7 This test method is used to measure and describe theresponse of materials, products or assemblies to heat and flameunder controlled conditions but does not by itself incorporateall factors required for the fire-hazard or fire-risk assessment ofthe materials, product
14、s, or assemblies under actual fire condi-tions.1.8 The values stated in inch-pound units are to be regardedas the standard. The SI values given in parentheses are forinformation only.1.9 The text of this test method references notes andfootnotes which provide explanatory material. These notes andfoo
15、tnotes (excluding those in tables and figures) shall not beconsidered as requirements of the standard.1This test method is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.11 on FireResistance.Current edition approved March 1, 2004.
