Designation:C162817Standard Specification forJoints for Concrete Gravity Flow Sewer Pipe,Using RubberGaskets1This standard is issued under the fixed designation C1628;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.1.Scope1.1 This specification covers flexible leak resistant joints forconcrete gravity flow sewer pipe using rubber gaskets forsealing the joints,where measurable or defined infiltration orexfiltration is a factor of the design.The specification coversthe design of joints and the requirements for rubber gaskets tobe used therewith,for pipe conforming in all other respects toSpecifications C14,C76,C655,C985,and C1417,providedthat,if there is conflict in permissible variations in dimension,the requirements of this specification shall govern for joints.NOTE1Infiltration or exfiltration quantities for an installed pipelineare dependent upon many factors other than the joints,and allowablequantities must be covered by other specifications and suitable testing ofthe installed pipeline and system.This specification covers the design,material,and performance of the rubber gasket joint only.Joints coveredby this specification are for hydrostatic pressures up to 13 psi withoutleakage,when plant tested in accordance with Section 10.1.2 The values stated in inch-pound units are to be regardedas standard.No other units of measurement are included in thisstandard.1.3 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:2C14 Specification for Nonreinforced Concrete Sewer,StormDrain,and Culvert PipeC76 Specification for Reinforced Concrete Culvert,StormDrain,and Sewer PipeC497 Test Methods for Concrete Pipe,Manhole Sections,orTileC655 Specification for Reinforced Concrete D-LoadCulvert,Storm Drain,and Sewer PipeC822 Terminology Relating to Concrete Pipe and RelatedProductsC985 Specification for Nonreinforced Concrete SpecifiedStrength Culvert,Storm Drain,and Sewer PipeC1417 Specification for Manufacture of Reinforced Con-crete Sewer,Storm Drain,and Culvert Pipe for DirectDesignC1619 Specification for Elastomeric Seals for Joining Con-crete Structures3.Terminology3.1 DefinitionsFor definitions of terms relating to concretepipe,see Terminology C822.4.Basis of Acceptance4.1 The acceptability of the pipe joints and gasket shall bedetermined by the approved design submittal information,results of the physical tests prescribed in this specification,andby inspection to determine whether the pipe joints and gasketsconform to this specification as to design and freedom fromdefects.5.Materials and Manufacture for Gaskets5.1 The gasket shall be fabricated from a rubber compound.The basic polymer shall be natural rubber,synthetic rubber,ora blend of both meeting the physical requirements prescribed inSpecification C1619.5.1.1 Gaskets for standard use shall meet Class E require-ments.Gaskets which require oil resistant properties shall meetClass B requirements.5.2 Circular Cross-Section Gaskets:5.2.1 Circular cross-section gaskets shall be extruded ormolded to the specified size within a tolerance of 6164in.or61.5%of the cord diameter,whichever is larger.5.2.2 Circular cross-section gaskets shall have the nominaldesign cut length tolerance of 63.0%for extruded and splicedgaskets.5.2.3 Each gasket shall be manufactured to provide thevolume of rubber required by the pipe manufacturers jointdesign with a tolerance of 63%for gaskets up to and including1This specification is under the jurisdiction of ASTM Committee C13 onConcrete Pipe and is the direct responsibility of Subcommittee C13.08 on Joints forPrecast Concrete Structures.Current edition approved Jan.1,2017.Published January 2017.Originallypublished in 2006.Last previous edition approved in 2011 as C1628 11.DOI:10.1520/C1628-17.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 l-in.in diameter and 61%for gaskets of 1-in.diameter andlarger.The allowable percentage tolerance
