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

32、knowledge and under-standing of the provisions 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 subjec

33、ted tospecific laboratory fire test exposure 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 descr

34、ibed in Test MethodE119,.5. General Principles5.1 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 orsubstituti

35、on of components in a test specimen.5.1.1 The 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.E2032 09 (2017)25.2 Statements in this guide only indicate whether a changein the const

36、ruction either “can reduce” or “does not reduce” thefire resistance rating.5.3 Limitations:5.3.1 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

37、 the identified changes arethe only changes 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 ident

38、ified does not change the specified load.5.3.4.1 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(

39、specified load, dead plus live load) to the 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/Unr

40、estrained Specimens:5.4.1 The fire resistance 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

41、a load bearing element isresisted by forces 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 res

42、trained beam, floor, or roof test speci-mens 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

43、elevated fire conditions.5.4.3 Ratings of unrestrained 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 resi

44、sting substantial thermalexpansion throughout 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 Dete

46、sign:5.5.1 Fire resistance ratings of beams 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

47、 tested in non-composite design shall be limited tobuilding constructions designed for non-composite action.6. Principles Pertaining to Heat Transfer Characteristicsof Concrete6.1 The provisions in this section are applicable only as theyaffect the transfer of heat through concrete. Considerationsin

48、volving structural fire resistance are addressed in othersections.6.2 For concrete test specimens where temperature rise onthe unexposed surface of a concrete slab (wall, floor, or roof)is the governing criterion, the following modifications do notreduce the fire resistance rating of the assembly:6.

49、2.1 Decrease in concrete unit weight;6.2.2 Substitution of sanded light-weight aggregate concreteor light-weight aggregate concrete for normal weight concrete;also, substitution of carbonate aggregate for siliceous aggre-gate for either the coarse or the fine aggregate used in theconcrete;6.2.3 Decrease in the nominal maximum size of coarseaggregate within a given concrete aggregate type;6.2.4 Increase or decrease in the compressive strength of theconcrete;6.2.5 Change in the type of portland cement, flyash oradmixtures used in the concrete;6.2.6 Changes
