3、er 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 unique building construction detail notaddressed by other fire test methods.Among
4、 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 induced by thermal differentials, seismicity, and wind loads.This test method describe
5、s 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 the multi-story test apparatus and this test methodare intended to simulate a pos
6、sible fire exposure on a perimeter fire barrier.1. Scope1.1 This test method measures the performance of the perimeter fire barrier and its ability to maintain a seal to prevent firespread during the deflection and deformation of the exterior wall assembly and floor assembly during the fire test, wh
7、ile resistingfire exposure from an interior compartment fire as well as from the flame plume emitted from the window burner below. The endpoint of the fire-resistance test is the period of time elapsing before the first condition of compliance is reached as the perimeterfire barrier is subjected to
8、a time-temperature fire exposure.1.2 The fire exposure conditions used are those specified by this test method for the first 30 min of exposure and then conformto the Test Methods E119 time-temperature curve for the remainder of the test in the test room.1.3 This test method specifies the heating co
9、nditions, methods of test, and criteria for evaluation of the ability of a perimeterfire barrier to maintain the fire resistance where a floor and exterior wall assembly are juxtaposed to a perimeter joint.1.4 Test results establish the performance of perimeter fire barriers during the fire-exposure
10、 period and shall not be construedas having determined the suitability of perimeter fire barriers for use after that exposure.1.5 This test method does not provide quantitative information about the perimeter fire barrier relative to the rate of leakage ofsmoke or gases or both. While it requires th
11、at such phenomena be noted and reported when describing the general behavior ofperimeter fire barrier during the fire-resistance test, such phenomena are not part of the conditions of compliance.1.6 Potentially important factors and fire characteristics not addressed by this test method include, but
12、 are not limited to:1.6.1 The performance of the perimeter fire barrier constructed with components other than those tested, and1.6.2 The cyclic movement capabilities of perimeter fire barriers other than the cycling conditions tested.1.7 This test method is used to measure and describe the response
13、 of materials, products or assemblies to heat and flame undercontrolled conditions but does not by itself incorporate all factors required for the fire-hazard or fire-risk assessment of thematerials, products, or assemblies under actual fire conditions.1.8 The values stated in inch-pound units are t
