29、t.4. Significance and Use4.1 The methods and procedures set forth in this guide relateto the extension of the fire resistance ratings obtained fromparticular fire tested specimens to constructions that have notbeen tested.4.2 Users of this guide must have knowledge and under-standing of the provisio
30、ns of Test Method E119 including thosepertaining to conditions of acceptance.4.3 In order to apply some of the principles described in thisguide, reference to the original fire test report will be necessary.4.4 In Test Method E119, the specimens are subjected tospecific laboratory fire test exposure
31、 conditions. Substitution ofdifferent test conditions or changes in the end use conditionshave the ability to change the measured fire-test-responsecharacteristics. Therefore, the extensions of data are valid onlyfor the fire test exposure conditions described in Test MethodE119,.5. General Principl
32、es5.1 The same criteria or conditions of acceptance as set outin the Test Method E119 and followed in the establishment ofthe fire resistance rating of the original test specimen shall beused in the evaluation of the effect of the modification orsubstitution of components in a test specimen.5.1.1 Th
33、e criteria or conditions of acceptance for the evalu-ation of modified test specimens shall likewise be in accor-dance with the appropriate sections of Test Method E119.5.2 Statements in this guide only indicate whether a changein the construction either “can reduce” or “does not reduce” thefire res
34、istance rating.5.3 Limitations:E2032 09 (2013)25.3.1 The extension of fire resistance ratings is valid onlyfor changes to the tested specimen that fall within normal andreasonable limits of standard construction practices.5.3.2 Statements are valid only if the identified changes arethe only changes
35、in the construction or properties of thecomponents.5.3.3 It is possible that multiple changes have a differentcumulative effect than that of individual changes appliedseparately.5.3.4 Unless otherwise indicated, statements are only validif the change identified does not change the specified load.5.3
36、.4.1 Provisions in this guide involving the ratio ofspecified load to design load assume that the safety factor (ratioof ultimate capacity to design load) inherent in the designprocedure is constant.5.3.4.2 Increasing the ratio of the maximum applied load(specified load, dead plus live load) to the
37、design load of anelement beyond that realized in the test specimen can reducethe fire resistance rating.5.3.5 Provisions in this guide pertaining to concrete onlyapply to concrete with a compressive strength of 55.1 MPa(8000 psi) or less.5.4 Restrained/Unrestrained Specimens:5.4.1 The fire resistanc
38、e rating of a beam, floor, or roof testspecimen is related to either a restrained or unrestrainedcondition, or both. A restrained condition in a fire test isconsidered to be one in which the displacement or rotation dueto fire induced thermal expansion of a load bearing element isresisted by forces
39、external to the element. An unrestrainedcondition in a fire test is one in which the load bearing elementis free to expand and rotate at its supports or is not subject tosubstantial thermal expansion and its resulting restrainingforces.5.4.2 Ratings of restrained beam, floor, or roof test speci-mens
40、 are intended for application to elements which areconsidered to be suitable for use in restrained building con-struction where the surrounding or supporting structure iscapable of resisting substantial thermal expansion throughoutthe range of anticipated elevated fire conditions.5.4.3 Ratings of un
41、restrained beam, floor or roof test speci-mens are intended for application to elements which areconsidered to be suitable for use in unrestrained and restrainedbuilding construction where the surrounding or supportingstructure is or is not capable of resisting substantial thermalexpansion throughou
42、t the range of anticipated elevated fireconditions.5.4.3.1 The application of unrestrained classified beams,floors or roofs for use in building constructions with endrestraint does not reduce the fire resistance rating.NOTE 1See Appendix X3 “Guide for Determining Conditions ofRestraint for Floor and
43、 Roof Assemblies and for Individual Beams” inTest Method E119 for assistance in determining the conditions of thermalrestraint applicable to floor and roof constructions and individual beams inactual building construction.5.5 Composite and Non-Composite Design:5.5.1 Fire resistance ratings of beams
44、and floors or roofstested with composite design between the beam and the floor orroof is not reduced in actual building constructions designedfor either composite or non-composite action.5.5.2 Conversely, fire resistance ratings of beams and floorsor roofs tested in non-composite design shall be lim
45、ited tobuilding constructions designed for non-composite action.6.
