Designation:D416114An American National StandardStandard Specification for“Fiberglass”(Glass-Fiber-Reinforced Thermosetting-Resin)Pipe Joints Using Flexible Elastomeric Seals1This standard is issued under the fixed designation D4161;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.Scope*1.1 This specification covers axially unrestrained bell-and-spigot gasket joints including couplings required for machine-made“fiberglass”(glass-fiber-reinforced thermosetting-resin)pipe systems,8 in.(200 mm)through 156 in.(4000 mm),usingflexible elastomeric seals to obtain soundness.The pipe sys-tems may be pressure(typically up to 250 psi)or nonpressuresystems for water or for chemicals or gases that are notdeleterious to the materials specified in this specification.Thisspecification covers materials,dimensions,test requirements,and methods of test.1.2 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are providedfor information purposes only.NOTE1There is a similar but technically different ISO Standard(ISO8639).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:2D883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsF412 Terminology Relating to Plastic Piping SystemsF477 Specification for Elastomeric Seals(Gaskets)for Join-ing Plastic Pipe3.Terminology3.1 Definitions:3.1.1 GeneralDefinitions and abbreviations are in accor-dance with Terminology D883 or Terminology F412,andTerminology D1600 unless otherwise indicated.4.Types of Joints4.1 This specification covers two types of axially unre-strained joints based on effecting soundness of the jointthrough compression of an elastomeric seal or ring:4.1.1 Bell-and-spigot or coupling joint with the gasketplaced in the bell in circumferential compression.An elasto-meric gasket joint design featuring a continuous elastomericring gasket placed in an annular space provided in the bell orsocket of the pipe or fitting.The spigot end of the pipe or fittingis forced into the bell,thereby compressing the gasket radiallyto form a positive seal.4.1.2 Bell-and-spigot or coupling joint with the gasketplaced on the spigot in circumferential tension:Apush on jointdesign featuring a continuous elastomeric ring gasket placed inan annular space provided on the spigot end of the pipe orfitting.The spigot is forced into the bell of the pipe or fitting,thereby compressing the gasket radially to form a positive seal.NOTE2A coupling joint of these types is a loose double-bell sleeveused to connect pipes which have spigots at both ends(see Fig.1).Allreferences to bells in this specification are applicable to the sleevecoupling as well as to the integral bell of a bell-and-spigot gasket joint.5.Materials and Manufacture5.1 The gasket shall be a continuous elastomeric ring ofcircular or other geometric cross section and shall meet therequirements of Specification F477,unless otherwise specifiedin this specification.When a splice is used in the manufactureof the gasket,no more than two splices shall be made in anyone gasket.5.1.1 The chemical composition of the gasket shall becompatible with the type of environment to which it will besubjected.Selection of the gasket composition shall be inaccordance with a purchaser and seller agreement.NOTE3Consult the gasket manufacturer for advice as to the suitabil-ity of specific rubber compounds for the intended service and jointconfigurations.Items such as cold set when the joint is deflected underlow-temperature conditions and maximum and minimum stretch in thegasket may be dependent upon the specific chemical compounds used.1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.23 on ReinforcedPlastic Piping Systems and Chemical Equipment.Current edition approved April 1,2014.Published April 2014.Originallyapproved in 1982.Last previous edition approved in 2010 as D4161 01(2010).DOI:10.1520/D4161-14.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 Materials in the bell and spigot of the joint shall meetthe requirements of the
