3、d editorially in November 2016.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 perimeter fire barrier is a

4、 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 variousmovements such as those indu

5、ced 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 apparatus (ISMA). The use of

6、 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 during the deflection and defo

7、rmation 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 elapsing before the first co

8、ndition 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 E119 time-temperature curve forthe remainder

9、 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 perimeterjoint.1.4 Test results est

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 Potentially important factors

12、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 the cycling conditions te
