Designation:F 2133 01An American National StandardStandard Test Methods forDetermining Effects of Large Hydrocarbon Pool Fires onInsulated Marine Bulkheads and Decks,Constructed ofSteel1This standard is issued under the fixed designation F 2133;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods described in this fire-test responsestandard are used for determining the fire-test response ofinsulated marine steel bulkheads and decks.The insulation iseither homogeneous or composite construction.1.2 It is the intent that tests conducted in accordance withthese test methods will indicate whether bulkheads and deckswill continue to perform their intended function during theperiod of fire exposure.These test methods shall not beconstrued as implying suitability for use after fire exposure.1.3 These test methods prescribe a standard fire exposurefor comparing the relative performance of different bulkheadand deck assemblies under controlled laboratory conditions.The application of these test results to predict the performanceof actual assemblies when exposed to large pool fires requiresa careful engineering evaluation.1.4 LimitationsThese test methods do not provide thefollowing:1.4.1 Full information on the performance of assembliesconstructed with components or of dimensions other than thosetested.1.4.2 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.1.4.3 Measurement of flame spread over the surface of thetest assembly.1.4.4 The erosive effect that the velocities or turbulence,orboth,generated in large pool fires has on some fire protectionmaterials.1.4.5 Full information on the performance of assemblies attimes less than 5 min because the rise time called out in Section6 is longer than that of a real fire.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for approximateinformation only.1.6 This standard measures and describes the response ofmaterials,products,or assemblies to heat and flame undercontrolled conditions,but does not by itself incorporate allfactors required for fire hazard or fire-risk assessment of thematerials,products,or assemblies under actual fire conditions.1.7 This test method is based on the fire exposure as definedin Test Methods E 1529(issued by the Committee on FireStandards,E05).1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:E 119 Test Methods for Fire Tests of Building Constructionand Materials2E 176 Terminology of Fire Standards2E 511 Test Method for Measuring Heat Flux Using aCopper-Constantan Circular Foil,Heat-Flux Gage3E 1529 Test Methods for Determining Effects of LargeHydrocarbon Pool Fires on Structural Members and As-semblies23.Terminology3.1 Definitions of Terms Specific to These Test MethodsRefer to Terminology E 176 for definitions of terms associatedwith fire issues used in these test methods.4.Summary of Test Methods4.1 The fire environment within the furnace shall develop atotal heat flux of 204 6 16 kW/m2(65 000 6 5000 Btu/ft2-h)and an average temperature of 1093 6 111C(2000 6 200F)within 5 min from the start of the test.The fire environmentshall be controlled by reproducing the furnace temperaturesrecorded during the furnace calibration method specified inSection 7.This temperature shall be maintained throughout theremainder of the fire test as shown in Fig.1.4.2 Performance is defined as the time period during whichbulkheads and decks will continue to perform their intended1These test methods are under the jurisdiction of ASTM Committee F25 onShips and Marine Technology and are the direct responsibility of SubcommitteeF25.02 on Insulation/Processes.Current edition approved July 10,2001.Published September 2001.2Annual Book of ASTM Standards,Vol 04.07.3Annual Book of ASTM Standards,Vol 15.03.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.function when subjected to fire exposure.The results arereported in terms of time increments such as 15,30,60,90,and120 min.5.Significance and Use5.1 These test methods are intended to provide a basis forevaluating the time period during which bulkheads and deckswill continue to perform its intended function when subjectedto a controlled,standardized fire exposure.5.1.1 In particular,the selected standard exposure conditionsimulates the condition of total continuous engulfment
