22、Method E814 including those pertaining to conditions of acceptance. 4.3 In order to apply some of the principles described in this guide, reference to the original re test report will be necessary. 4.4 In Test Method E814, the specimens are subjected to specic laboratory re test exposure conditions.
23、 Differences between the tested assembly and the as-built assembly impact the re-test-response characteristics. Substitution of different test conditions also impacts the re-test-response characteristics. 4.5 The extension of data is valid only for the re test exposure described in Test Method E814.
24、 4.6 This guide shall not be used to extrapolate the re resistance rating to a higher value. 4.7 Limitations: 4.7.1 The extension of re resistance data is to be used only for changes to the tested specimen that fall within normal and reasonable limits of accepted construction practices. 4.7.2 Conclu
25、sions derived from using this guide are valid only if the identied change is the only change in the construction or properties of the components. 4.7.3 Evaluationofchangestothere-resistiveassemblyinwhichtherestopisinstalledisgovernedbytheExtensionofData principles in Guide E2032. 2 ForreferencedASTM

General Principles 5.1 The principles in this section shall apply to all subsequent sections. 5.2 The rating criteria and conditions of accept
32、ance as set out inTest Method E814 shall be used in the evaluation of the effect of the change to the restop system. 5.3 Conclusions derived from using this guide indicate only whether or not a change in the application or design of the restop system reduces the re resistance rating. 5.4 The restop
33、system is limited to the maximum dimensions of the opening in the assembly that have been re tested according to E814 or E119 under positive furnace pressure as specied in E814. 5.5 The restop product(s) is limited to the product(s) re tested. 5.6 Angled PenetrationsWhere the penetrating item is ind

35、or assembly. In all other cases, except where otherwise indicated in the system, the penetrating item shall penetrate the wall or oor assembly at a 90 angle. 6. Principles for Firestops NOTE 3Information regarding the re resistance of the wall or oor assemblies can be found in Guide E2032 or ACI 216
36、. See Appendix X3 for additional information. 6.1 Concrete or Masonry Assemblies: 6.1.1 Increase in thickness of the assembly will not decrease the re resistance of the restop. Exception: Where it is known or suspected that locating a material further from the re or on the unexposed side of the asse
37、mbly will reduce the F-rating. 6.1.2 Firestop systems tested in concrete oor assemblies can be used in concrete or masonry wall assemblies providing that they 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 t
38、hey are symmetrical and equidistant from both surfaces. 6.1.3 Firestop systems re tested in wall assemblies cannot be installed in oor assemblies unless re tested according to Test Method E814 as a oor assembly. 6.1.4 Firestop systems can be used in concrete or masonry assemblies of equal or lower r
39、e resistance as long as the Firestop system tested design is not modied in relation to restop thickness, bonding and support, and is not modied in relation to the assembly thickness. 6.2 Gypsum Board Wall Assemblies: 6.2.1 Increase in the depth of studs or thickness or number of layers of gypsum boa
40、rd will not decrease the re resistance of the restop.Exception 1: Where the restop materials are 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. NOTE 4Wher
41、e it is known or suspected that locating a material further from the re or on the unexposed side of the assembly will reduce the resistance to the test. Exception 3: Where it is known that locating a material on the non-re side of the assembly further from the re will reduce the performance of the r
42、estop. 6.2.2 Firestop systems cannot be used in assemblies of lower resistance ratings without re testing. E275013 3Exception:Arestop system that is tested and listed for a symmetrical gypsum wall assembly that includes multiple layers of gypsum board per side, can be used to maintain the re resista
43、nce rating of a gypsum wall assembly that includes fewer layers of gypsum board per side, as long as the sealant depth in the listed system, does not exceed the thickness of that reduced number of layers of gypsum board. 6.2.3 Symmetrical Installations: 6.2.3.1 The results of the re resistance test
44、are deemed to be applicable to a similar type of untested system providing the following are true. (1)The maximum dimension of the opening is not increased. (2)The total area of the opening is not increased. (3)Neither the restop product(s) or damming material is changed. (4)The thickness of neither
45、 the restop product(s) or damming material is decreased. 6.2.3.2 Refer to 6.1 for restrictions 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
46、 restop is in the same position relative to the heat source, and (2) the restop is at least in contact with the same material as tested; 6.3.1.1 Increase in the depth of joists or trusses, 6.3.1.2 Increase in thickness or number of layers of gypsum board, 6.3.1.3 Increase in the overall assembly thi
47、ckness due to additional oor coverings or ceiling nishes. Exception 1: In assemblies where there are restop materials not part of the exposed side that is part of the tested or listed restop conguration. Exception 2: Where it is known or suspected that locating a material further from the re or on t
48、he unexposed side of the assembly will reduce the resistance to the test. 6.3.2 Firestopsystemscannotbeusedinassembliesoflowerresistanceratingswithoutretesting.Exception:Arestopsystem that is tested and listed for a oor/ceiling assembly that includes multiple layers of gypsum board, can be used to m
49、aintain the re resistance rating of a oor/ceiling assembly that includes fewer layers of gypsum board, as long as the sealant depth in the listed system, does not exceed the thickness of that reduced number of layers of gypsum board. 6.4 Floor/Ceiling Assembly with Concrete Floor: NOTE 5This section does not apply to oor/ceiling assemblies protected with direct applied reproong. 6.4.1 The following changes, individually or in combination, would not reduce the F-r
