15、substitution of one proprietary material for another proprietary material, or materials forwhich fire-test data are not presently available.1.11 This guide is used to predict or provide a quantitative measure of the fire hazard from a specified set of fire conditionsinvolving specific materials, pro

This assessment does not necessarily predict the hazard of actual fires whichinvolve conditions other than those assumed in the analysis.1.12 This guide is used to measure and describe the response of materials, products, or assemblies to heat and flame undercontrolled conditio

23、ds and procedures set forth in this guide relate to the extension of the fire test results to firestop systems that havenot been tested.4.2 Users of this guide must have knowledge and understanding of the provisions of Test Method E119 and Test Method E814including those pertaining to conditions of
24、acceptance.4.3 In order to apply some of the principles described in this guide, reference to the original fire test report will be necessary.4.4 In Test Method E814, the specimens are subjected to specific laboratory fire test exposure conditions. Differences betweenthe tested assembly and the as-b
25、uilt assembly impact the fire-test-response characteristics. Substitution of different test conditionsalso impacts the fire-test-response characteristics.4.5 The extension of data is valid only for the fire test exposure described in Test Method E814.4.6 This guide shall not be used to extrapolate t
26、he fire resistance rating to a higher value.4.7 Limitations:4.7.1 The extension of fire resistance data is to be used only for changes to the tested specimen that fall within normal andreasonable limits of accepted construction practices.2 For referencedASTM standards, visit theASTM website, www.ast

See Appendix X3 foradditional information.6.1 Concrete or Masonry Assemblies:6.1.1 Increase in thickness of
39、the assembly will not decrease the fire resistance of the firestop. Exception: Where it is knownor suspected that locating a material further from the fire or on the unexposed side of the assembly will reduce the F-rating.6.1.2 Firestop systems tested in concrete floor assemblies can be used in conc
40、rete or masonry wall assemblies providing thatthey are installed symmetrically on both sides of the wall.6.1.2.1 Firestop systems need not be installed on both sides of the wall assembly if they are symmetrical and equidistant fromboth surfaces.6.1.3 Firestop systems fire tested in wall assemblies c
41、annot be installed in floor assemblies unless fire tested according to TestMethod E814 as a floor assembly.6.1.4 Firestop systems can be used in concrete or masonry assemblies of equal or lower fire resistance as long as the Firestopsystem tested design is not modified in relation to firestop thickn
42、ess, bonding and support, and is not modified in relation to theassembly thickness.6.2 Gypsum Board Wall Assemblies:6.2.1 Increase in the depth of studs or thickness or number of layers of gypsum board will not decrease the fire resistance ofthe firestop.Exception 1: Where the firestop materials are
43、 at different positions within the assembly relative to the heat source.Exception 2: In assemblies where the active components on both sides of the assembly contribute to the test performance.E2750 173NOTE 4Where it is known or suspected that locating a material further from the fire or on the unexp
44、osed side of the assembly will reduce theresistance to the test.Exception 3: Where it is known that locating a material on the non-fire side of the assembly further from the fire will reducethe performance of the firestop.6.2.2 Firestop systems cannot be used in assemblies of lower resistance rating
45、s without fire testing.Exception: A firestop system that is tested and listed for a symmetrical gypsum wall assembly that includes multiple layers ofgypsum board per side, can be used to maintain the fire resistance rating of a gypsum wall assembly that includes fewer layersof gypsum board per side,
46、 as long as the sealant depth in the listed system, does not exceed the thickness of that reduced numberof layers of gypsum board.6.2.3 Symmetrical Installations:6.2.3.1 The results of the fire resistance test are deemed to be applicable to a similar type of untested system providing thefollowing ar
47、e true.(1) The maximum dimension of the opening is not increased.(2) The total area of the opening is not increased.(3) Neither the firestop product(s) or damming material is changed.(4) The thickness of neither the firestop product(s) or damming material is decreased.6.2.3.2 Refer to 6.1 for restri
48、ctions related to changes in the supporting construction.6.3 Wood Deck Floor/Ceiling Assemblies:6.3.1 The following changes, individually or in combination, would not reduce the F-rating, provided that: (1) the firestop isin the same position relative to the heat source, and (2) the firestop is at l
