Designation:F112204(Reapproved 2015)1An American National StandardStandard Specification forQuick Disconnect Couplings(6 in.NPS and Smaller)1This standard is issued under the fixed designation F1122;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.1NOTEKeywords section was editorially added in May 2015.1.Scope1.1 This specification covers the manufacturing data re-quired to produce a variety of styles and sizes of quickdisconnect couplings up to and including NPS 6 for marine usethat ensure interchangeability and safety of operation.1.2 In general,quick disconnect couplings are hose and pipeend fittings that permit quick mechanical attachment by meansother than bolted or threaded fittings.The method of attach-ment is a male coupling half(adapter)that fits into a femalecoupling half(coupler)of the same size.By closing attachedcam handles,the coupling halves seal,permitting fluids to betransported under pressure through the quick disconnect cou-pling.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 The following safety hazards caveat pertains only to thetest method described in this specification:This standard doesnot purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2.Referenced Documents2.1 ANSI Standards:2B2.1 Pipe ThreadsB16.5 Pipe Flanges and Flanged Fittings,Steel-NickelAlloy,and Other Special AlloysB16.24 Bronze Pipe Flanges and Flanged FittingsB16.42 Ductile Iron Pipe Flanges and Flanged FittingsB31.1 Power Piping Code2.2 MSS Standards:3MSS-SP-6 Standard Finish for Contact Faces of PipeFlanges and Connecting End Flanges of Valves andFittingsMSS-SP-25 Standard Marking System for Valves,Fittings,Flanges,and UnionsMSS-SP-55 Quality Standard for Steel Castings for Valves,Flanges,and Fittings and Other Piping Components(Vi-sual Method)2.3 ASME Standards:4Section VIII,Division 1 Pressure VesselsSection IX,Welding and Brazing Qualifications3.Definitions of Terms Specific to This Standard3.1 adapterone half of a quick disconnect coupling thatfits into the coupler and seals against an elastomer gasketpositioned inside the coupler.3.2 cam handleshandles that are assembled to the couplerhalf which by closing engages the adapter sealing the coupling.3.3 couplerone half of a quick disconnect coupling thatreceives the adapter.This half contains the sealing gasket andcam handles(see Fig.1).NOTE1See Fig.2 for a description of typical coupler pipe fittings.4.Classification4.1 Quick disconnect couplings shall consist of the follow-ing types:4.1.1 Standard ClassThis type is to be designed for a 4:1burst factor of safety.4.1.2 Class IThis type is to be designed for a 5:1 burstfactor of safety.4.2 Both Standard Class and Class I will be called quickdisconnect couplings in the body of this specification unlessotherwise specified.1This specification is under the jurisdiction of ASTM Committee F25 on Shipsand Marine Technology and is the direct responsibility of Subcommittee F25.11 onMachinery and Piping Systems.Current edition approved May 1,2015.Published June 2015.Originallyapproved in 1987.Last previous edition approved in 2010 as F1122 04(2010).DOI:10.1520/F1122-04R15.2Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.3Available from Manufacturers Standardization Society of the Valve and FittingsIndustry(MSS),127 Park St.,NE,Vienna,VA 22180-4602,http:/www.mss-.4Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Ordering Information5.1 Purchase orders for quick disconnect couplings underthis specification shall include the following applicable infor-mation:5.1.1 Class.5.1.2 Size and type of each coupling half-end connection.(Example:2-by 112-in.NPT).5.1.3 ASTM material designation and date including alloyspecifications for the following:5.1.3.1 Adapter and coupler halves,5.1.3.2 Cam handle,and5.1.3.3 Cam handle pivot pin.5.1.4 Product or fluid in applicable system.5.1.5 Shipping instructions.5.1.6 Any special requirements,such as testing,coatings,and threads.6.Materials and Manufacture6.1 Materials:6.1.1 Pressure-retaining parts shall be manufactured frommaterial specifications and grades listed in Section VIII,Division 1,of the ASME Boiler an
