Designation:D384014An American National StandardStandard Specification for“Fiberglass”(Glass-Fiber-Reinforced Thermosetting-Resin)Pipe Fittings for Nonpressure Applications1This standard is issued under the fixed designation D3840;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 fiberglass pipe fittings in-tended for use in gravity flow systems for conveying sanitarysewage,storm water,and those industrial wastes for which thefittings are determined to be suitable.Elbows,tees,laterals,crosses,reducers,and adapters are included.Both glass-fiber-reinforced thermosetting-resin pipe(RTRP)and glass-fiber-reinforced polymer mortar pipe(RPMP)are fiberglass pipes.NOTE1For the purposes of this standard,polymer does not includenatural polymers.1.2 This specification is intended to cover only dimensions,material properties,and workmanship rather than the structuraldesign of the fittings.The structural design of the fittings shallbe as agreed upon between purchaser and supplier,and needsto take into consideration the anticipated conditions of instal-lation and service.1.3 This specification covers only fittings fabricated fromcut sections of pipe,or from a combination of pipe sections andcontact molded(hand layup),or machine fabricated compo-nents.1.4 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are providedfor information purposes only.1.5 The following safety hazards caveat pertains only to thetest method portion,Section 11,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.NOTE2There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D638 Test Method for Tensile Properties of PlasticsD883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD1763 Specification for Epoxy ResinsD2290 Test Method for Apparent Hoop Tensile Strength ofPlastic or Reinforced Plastic PipeD3262 Specificationfor“Fiberglass”(Glass-Fiber-Reinforced Thermosetting-Resin)Sewer PipeD3567 Practice for Determining Dimensions of“Fiberglass”(Glass-Fiber-Reinforced Thermosetting Resin)Pipe andFittingsD3892 Practice for Packaging/Packing of PlasticsF412 Terminology Relating to Plastic Piping SystemsF477 Specification for Elastomeric Seals(Gaskets)for Join-ing Plastic Pipe3.Terminology3.1 Definitions:3.1.1 GeneralDefinitions are in accordance with Termi-nologies D883 and F412.Abbreviations are in accordance withTerminology D1600,unless otherwise indicated.3.2 Definitions of Terms Specific to This Standard:3.2.1 fiberglass pipea tubular product containing glassfiber reinforcements embedded in or surrounded by curedthermosetting resin.It is acceptable for the composite structureto contain aggregate,granular or platelet fillers,thixotropicagents,pigments or dyes.It is acceptable to include thermo-plastic or thermosetting liners or coatings.3.2.2 reinforced polymer mortar pipea fiberglass pipewith aggregate.3.2.3 reinforced thermosetting resin pipea fiberglass pipewithout aggregate.3.2.4 qualificationOne or more tests used to prove thedesign of a product.Not a routine quality control test.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 1979.Last previous edition approved in 2010 as D3840 10.Thisspecification replaces Specification D4160.DOI:10.1520/D3840-14.2For 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 NOTE3Qualification requirements appear in 6.1,7.2,and 12.3.4.Materials4.1 Laminating Resin:4.1.1 Type 1Polyester thermosetting resin,with or withoutfillers or thixotropic agents or both.NOTE4For the purpose of this standard,polyester includes vinyl esterresins.4.1.2 Type 2Epoxy resin,conforming to the requirementsof Specification D1763,with or without fillers or thixotropicagents,or both.4.2 Reinforcement:4.2.1 Grade 1A commercial grade of glass fibers with apolyester-compatible finish.4.2.2 Grade 2A commercial grade of glass fibers w
