Designation:E152914aAn American National StandardStandard Test Methods forDetermining Effects of Large Hydrocarbon Pool Fires onStructural Members and Assemblies1This standard is issued under the fixed designation E1529;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe performance of structural members and assemblies exposed to fire conditions resulting fromlarge,free-burning(that is,outdoors),fluid-hydrocarbon-fueled pool fires is of concern in the designof hydrocarbon processing industry(HPI)facilities and other facilities subject to these types of fires.In recognition of this unique fire protection problem,it is generally required that critical structuralmembers and assemblies be of fire-resistant construction.Historically,such requirements have been based upon tests conducted in accordance with TestMethods E119,the only available standardized test for fire resistant construction.However,theexposure specified in Test Methods E119 does not adequately characterize large hydrocarbon poolfires.Test Methods E119 is used for representation of building fires where the primary fuel is solid innature,and in which there are significant constraints on the movement of air to the fire,and thecombustion products away from the fire(that is,through doors,windows).In contrast,neithercondition is typical of large hydrocarbon pool fires(see Appendix X1 on Commentary).One of the most distinguishing features of the pool fire is the rapid development of hightemperatures and heat fluxes that can subject exposed structural members and assemblies to a thermalshock much greater than that associated with Test Methods E119.As a result,it is important that fireresistance requirements for HPI assemblies of all types of materials be evaluated and specified inaccordance with a standardized test that is more representative of the anticipated fire conditions.Sucha standard is found in the test methods herein.1.Scope*1.1 The test methods described in this fire-test-responsestandard are used for determining the fire-test response ofcolumns,girders,beams or similar structural members,andfire-containment walls,of either homogeneous or compositeconstruction,that are employed in HPI or other facilitiessubject to large hydrocarbon pool fires.1.2 It is the intent that tests conducted in accordance withthese test methods will indicate whether structural members ofassemblies,or fire-containment wall assemblies,will continueto perform their intended function during the period of fireexposure.These tests shall not be construed as having deter-mined suitability for use after fire exposure.1.3 These test methods prescribe a standard fire exposurefor comparing the relative performance of different structuraland fire-containment wall assemblies under controlled labora-tory conditions.The application of these test results to predictthe performance of actual assemblies when exposed to largepool fires requires a careful engineering evaluation.1.4 These test methods provide for quantitative heat fluxmeasurements during both the control calibration and theactual test.These heat flux measurements are being made tosupport the development of design fires and the use of firesafety engineering models to predict thermal exposure andmaterial performance in a wide range of fire scenarios.1.5 These test methods are useful for testing other itemssuch as piping,electrical circuits in conduit,floors or decks,and cable trays.Testing of these types of items requiresdevelopment of appropriate specimen details and end-point orfailure criteria.Such failure criteria and test specimen descrip-tions are not provided in these test methods.1.6 LimitationsThese test methods do not provide thefollowing:1.6.1 Full information on the performance of assembliesconstructed with components or of dimensions other than thosetested.1These test methods are under the jurisdiction of ASTM Committee E05 on FireStandards and are the direct responsibility of Subcommittee E05.11 on FireResistance.Current edition approved Dec.15,2014.Published December 2014.Originallyapproved in 1993.Last previous edition approved in 2014 as E1529 14.DOI:10.1520/E1529-14A.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 1.6.2 An evaluation of the degree to which the assemblycontributes to the fire hazard through the generation of smoke,toxic gases,or other products of combustion.1.6.3 Simulation of fire behavior of joints or connectionsbetween structural elements such as beam-to-column connec-tions.1.6.4 Measurement of flame spread over the surface of thetest assembly.1.6.5 Procedures for measuring the test performance ofother structural
