Designation:C164406(Reapproved 2011)Standard Specification forResilient Connectors Between Reinforced Concrete On-SiteWastewater Tanks and Pipes1This standard is issued under the fixed designation C1644;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 reinforced concrete tanks used for septic effluenttreatment/detention,including those referenced in Specifica-tions C913 and C1227.1.1.1 These connectors are designed to eliminate leakagebetween the pipe(s)and tank.1.2 A complete metric companion to Specification C1644has been developedC1644M;therefore,no metric equiva-lents are presented in this specification.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 5 psi(11.5 ft)without leakage when tested in accordance with Section 7.Infiltration orexfiltration quantities for an installed system are dependent upon manyfactors other than the connectors between tanks and pipes,and allowablequantities must be covered by other specifications and suitable testing ofthe installed pipe and system.1.3 The following precautionary caveat pertains only to thetest methods portion,Section 7,of this specification.Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2A240/A240M Specification for Chromium and Chromium-Nickel Stainless Steel Plate,Sheet,and Strip for PressureVessels and for General ApplicationsC822 Terminology Relating to Concrete Pipe and RelatedProductsC913 Specification for Precast Concrete Water and Waste-water StructuresC1227 Specification for Precast Concrete Septic TanksD395 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 ElastomersD746 Test Method for Brittleness Temperature of Plasticsand Elastomers by ImpactD883 Terminology Relating to PlasticsD1149 Test Methods for Rubber DeteriorationCracking inan Ozone Controlled EnvironmentD1566 Terminology Relating to RubberD2240 Test Method for Rubber PropertyDurometer Hard-ness3.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 tanks,and relatedproducts shall be as defined in Terminology C822 and asmodified in 3.1.3 3.1.5.3.1.3 connectorthe entire assembly including resilientseals and metallic or nonmetallic mechanical devices,if any,used therein.3.1.4 pipethe inlet or outlet pipe connected to the tank.3.1.5 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 be suitable for use in sanitary sewageapplications.4.1.1 Resilient MaterialsResilient materials for connec-tors shall be manufactured from natural or synthetic materialsand shall conform to the requirements prescribed in Table 11This specification is under the jurisdiction ofASTM Committee C27 on PrecastConcrete Products and is the direct responsibility of Subcommittee C27.30 on Waterand Wastewater Containers.Current edition approved May 1,2011.Published June 2011.Originallyapproved in 2006.Last previous edition approved in 2006 as C1644 06.DOI:10.1520/C1644-06R11.2For 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 and 4.1.If a splice is used in the manufacture of the seal,itsstrength shall be such that the splice can withstand a 180 bendwith no visible separation.4.1.2 Mechanical DevicesExpansion rings,tension bands,and take-up devices used for mechanically compressing theresilient portion of the connector against the pipe,or tank shallbe made from a material or materials in combination that willensure durability,strength,resistance to corrosion,and haveproperties that will ensure con
