Designation:C1478M08a(Reapproved 2013)Standard 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.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 requirements prior to use.For a specificwarning statement,see 7.2.4.2.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 AirOvenF624 Guide for Evaluation of Thermoplastic PolyurethaneSolids and Solutions for Biomedical ApplicationsD883 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-nessNOTE2For more information about wastewater structures,see Speci-fication C913.3.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,andrelated products shall be as defined in Terminology C822.3.2 Definitions of Terms Specific to This Standard:3.2.1 connectorthe entire assembly,including resilientseals and metallic or nonmetallic mechanical devices,if any,used therein.3.2.2 lateralthe small diameter pipe connected to themain line pipe.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 July 1,2013.Published July 2013.Originally approvedin 2003.Last previous edition approved in 2008 as C1478M 08a.DOI:10.1520/C1478M-08AR13.2For 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 3.2.3 pipethe inlet or outlet pipe connected to the man-hole.3.2.4 pipe stuba short section of pipe installed in thestructure as an inlet or outlet pipe,for future connection.4.Materials and Manufacture4.1 All materials shall conform to the following require-ments:4.1.1 Resilient materials for connectors and filler rings shallbe manufactured from natural or synthetic rubber and shallconform to the requirements prescribed in Table 1.If a spliceis used in the manufacture of the seal,its strength shall be suchthat the seal shall withstand a 180 bend with no visibleseparation.4.2 Mechanical DevicesExpansion rings,tension bands,and take-up devices used for mechanically compressing theresilient portio
