Designation:C1478M19Standard Specification forStorm Drain Resilient Connectors Between ReinforcedConcrete Storm Sewer Structures,Pipes,and Laterals(Metric)1This standard is issued under the fixed designation C1478M;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 the minimum performance andmaterial requirements for resilient connectors used for connec-tions between precast reinforced concrete storm sewer struc-tures conforming to Specification C478 and pipes,and betweenprecast reinforced concrete pipe and laterals for storm drainagesystems.1.1.1 These connectors are designed to prevent soil migra-tion between the pipe and storm sewer structure,and betweenthe pipe and lateral.1.2 This specification is the SI companion to C1478.NOTE1This specification covers the design,material,and perfor-mance of the resilient connection only.Connections covered by thisspecification are adequate for hydrostatic pressures up to 41 kPa(4.3 m)without leakage when tested in accordance with Section 7.Infiltrationquantities for an installed system are dependent upon many factors otherthan the connections between storm sewer structures and pipe,andallowable quantities must be covered by other specifications and suitabletesting of the installed pipeline and system.NOTE2For installations that exceed 41 kPa(4.3 m),the user iscautioned to verify the amount of hydrostatic head pressure the connectorwill experience.If the total pressure applied to the connector exceeds the41 kPa limits of the specification,the user is advised to contact theconnector manufacturer for alternative methods of connecting the pipe,orapplicable alternative standards.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For a specific warning statement,see 7.2.4.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2A493 Specification for Stainless Steel Wire and Wire Rodsfor Cold Heading and Cold ForgingA666 Specification for Annealed or Cold-Worked AusteniticStainless Steel Sheet,Strip,Plate,and Flat BarC478 Specification for Circular Precast Reinforced ConcreteManhole SectionsC822 Terminology Relating to Concrete Pipe and RelatedProductsC913 Specification for Precast Concrete Water and Waste-water StructuresD395 Test Methods for Rubber PropertyCompression SetD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD573 Test Method for RubberDeterioration in an AirOvenD624 Test Method for Tear Strength of Conventional Vul-canized Rubber and Thermoplastic ElastomersD883 Terminology Relating to PlasticsD1149 Test Methods for Rubber DeteriorationCracking inan Ozone Controlled EnvironmentD1566 Terminology Relating to RubberD2137 Test Methods for Rubber PropertyBrittleness Pointof Flexible Polymers and Coated FabricsD2240 Test Method for Rubber PropertyDurometer Hard-nessNOTE3For more information about wastewater structures,see Speci-fication C913.1This specification is under the jurisdiction of ASTM Committee C13 onConcrete Pipe and is the direct responsibility of Subcommittee C13.06 on Manholesand Specials.Current edition approved March 1,2019.Published March 2019.Originallyapproved in 2003.Last previous edition approved in 2018 as C1478M 18.DOI:10.1520/C1478M-19.2For 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 3.Terminology3.1 Definitions:3.1.1 Terms relating to plastics and rubber shall be asdefined in Terminologies D883 and D1566,respectively.3.1.2 Terms relating to precast concrete pipe,manholes,andrela
