Designation:A760/A760M15Standard Specification forCorrugated Steel Pipe,Metallic-Coated for Sewers andDrains1This standard is issued under the fixed designation A760/A760M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers corrugated steel pipe intendedfor use for storm water drainage,underdrains,the constructionof culverts,and similar uses.Pipe covered by this specificationis not normally used for the conveyance of sanitary orindustrial wastes.The steel sheet used in fabrication of the pipehas a protective metallic coating of zinc(galvanizing),aluminum,55%aluminum-zinc alloy,or zinc-5%aluminum-mischmetal alloy.1.2 The several different metallic coatings may not provideequal protection of the base metal against corrosion or abrasionin all environments,or both.Some environments may be sosevere that none of the metallic coatings included in thisspecification will provide adequate protection.Additional pro-tection for corrugated steel pipe can be provided by use ofcoatings applied after fabrication of the pipe as described inSpecification A849,or by use of polymer precoated corrugatedsteel pipe as described in Specification A762/A762M.1.3 Section 9 is intended to be applied to corrugated steelpipe joints.The several different types of corrugated steel pipejoints provide various qualities.This specification is notintended for routine quality control testing or in-field accep-tance testing,but is intended to establish performance limits ofthe pipe joints,as well as the test requirements and testmethods for the joints as described herein.1.4 This specification does not include requirements forbedding,backfill,or the relationship between earth cover loadand sheet thickness of the pipe.Experience has shown that thesuccessful performance of this product depends upon theproper selection of sheet thickness,type of bedding andbackfill,controlled manufacture in the plant,and care in theinstallation.The installation procedure is described in PracticeA798/A798M.1.5 This specification is applicable to orders in eitherinch-pound units as A760 or in SI units as A760M.Inch-poundunits and SI units are not necessarily equivalent.SI units areshown in brackets in the text for clarity,but they are theapplicable values when the material is ordered to A760M.2.Referenced Documents2.1 ASTM Standards:2A90/A90M Test Method for Weight Mass of Coating onIron and Steel Articles with Zinc or Zinc-Alloy CoatingsA153/A153M Specification for Zinc Coating(Hot-Dip)onIron and Steel HardwareA307 Specification for Carbon Steel Bolts,Studs,andThreaded Rod 60 000 PSI Tensile StrengthA428/A428M Test Method for Weight Mass of Coating onAluminum-Coated Iron or Steel ArticlesA449 Specification for Hex Cap Screws,Bolts and Studs,Steel,Heat Treated,120/105/90 ksi Minimum TensileStrength,General UseA563 Specification for Carbon and Alloy Steel NutsA563M Specification for Carbon andAlloy Steel Nuts(Met-ric)A742/A742M Specification for Steel Sheet,Metallic Coatedand Polymer Precoated for Corrugated Steel PipeA762/A762M Specification for Corrugated Steel Pipe,Poly-mer Precoated for Sewers and DrainsA780 Practice for Repair of Damaged and Uncoated Areasof Hot-Dip Galvanized CoatingsA796/A796M Practice for Structural Design of CorrugatedSteel Pipe,Pipe-Arches,and Arches for Storm and Sani-tary Sewers and Other Buried ApplicationsA798/A798M Practice for Installing Factory-Made Corru-gated Steel Pipe for Sewers and Other ApplicationsA849 Specification for Post-Applied Coatings,Pavings,andLinings for Corrugated Steel Sewer and Drainage PipeA929/A929M Specification for Steel Sheet,Metallic-Coatedby the Hot-Dip Process for Corrugated Steel PipeB633 Specification for Electrodeposited Coatings of Zinc onIron and Steel1This specification is under the jurisdiction of ASTM Committee A05 onMetallic-Coated Iron and Steel Products and is the direct responsibility ofSubcommittee A05.17 on Corrugated Steel Pipe Specifications.Current edition approved May 1,2015.Published May 2015.Originallyapproved in 1979.Last previous edition approved in 2013 as A760/A760M-13.DOI:10.1520/A0760_A0760M-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 B695 Specification for Coatings of Zinc Mechanically De-posited on Iron and SteelC1619 Specification for Elastomeric Seals for Joining Con-crete StructuresD1056 Specification for Flexible Cellular MaterialsSponge or Expanded RubberF568M Specification for Carbon and Alloy Steel Ext
