Designation:D231006(Reapproved 2012)An American National StandardStandard Classification forMachine-Made“Fiberglass”(Glass-Fiber-ReinforcedThermosetting-Resin)Pipe1This standard is issued under the fixed designation D2310;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.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This classification covers machine-made“fiberglass”(glass-fiber-reinforced thermosetting-resin)pressure pipe.Methods of classification,requirements,test methods and themethod of marking are included.Both glass-fiber-reinforcedthermosetting-resin pipe(RTRP)and glass-fiber-reinforcedpolymer mortar pipe(RPMP)are fiberglass pipes.NOTE1For the purposes of this standard,polymer does not includenatural polymers.1.2 This classification is based on the method ofmanufacture,the type of materials used in construction,and thetest performance of the product type.It is not based ondimensions or raw material specifications.1.3 Two methods of classifying long-term strength areincluded:(1)based on cyclic loads for use in those liquid-handling applications where the effects of pumping by duplexor triplex pumps or other cyclic pressure loads dictate theperformance requirements of the piping,and(2)based on thesteady(static)loads such as would be required for gas serviceapplications.1.4 The values stated in inch-pound units are to regarded asthe standard.The values in parentheses are provided forinformation only.1.5 The following precautionary caveat pertains only to thetest method portion,Section 7,of this classification.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.NOTE2There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD2992 Practice for Obtaining Hydrostatic or Pressure De-sign Basis for“Fiberglass”(Glass-Fiber-ReinforcedThermosetting-Resin)Pipe and FittingsD3567 Practice for Determining Dimensions of“Fiberglass”(Glass-Fiber-Reinforced Thermosetting Resin)Pipe andFittingsF412 Terminology Relating to Plastic Piping Systems3.Terminology3.1 GeneralDefinitions are in accordance with Terminol-ogy D883 or F412 and abbreviations are in accordance withTerminology D1600,unless otherwise indicated.3.2 Definitions of Terms Specific to This Standard:3.2.1 fiberglass pipe,na tubular product containing glassfiber reinforcements embedded in or surrounded by curedthermosetting resin;the composite structure may containaggregate,granular,or platelet fillers,thixotropic agents,pigments,or dyes;thermoplastic or thermosetting liners orcoatings may be included.3.2.2 reinforced thermosetting resin pipe(RTRP),na fi-berglass pipe without aggregate.3.2.3 reinforced polymer mortar pipe(RPMP),na fiber-glass pipe with aggregate.3.2.4 centrifugal casting,n a manufacturing process usedto produce tubular goods by applying resin and reinforcementto the inside of a mold that is rotated and heated,subsequentlypolymerizing the resin system.The outside diameter of thefinished pipe is fixed by the inside diameter of the mold tube.The inside diameter of the pipe is determined by the amount ofmaterial introduced into the mold.1This classification 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 Oct.1,2012.Published October 2012.Originallyapproved in 1964.Last previous edition approved in 2006 as D2310 06.DOI:10.1520/D2310-06R12.2For 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 3.2.5 filament winding,na process used to manufacturetubular goods by winding continuous fibrous glass strandroving or roving tape onto the outside of a mandrel in apredetermined pattern under controlled tension;the roving maybe saturated with liquid resin or preimpregnated with partiallycured resin;subsequent polymerization of the resin system mayrequire application of heat;the inside diameter of the finishedpipe is fixed by the mandrel outside diameter;the outsidediameter of the finished pipe is determined by the amount ofmaterial th
