Designation:D356797(Reapproved 2011)An American National StandardStandard Practice forDetermining Dimensions of“Fiberglass”(Glass-Fiber-Reinforced Thermosetting Resin)Pipe and Fittings1This standard is issued under the fixed designation D3567;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 U.S.Department of Defense.1.Scope1.1 This practice covers the determination of outsidediameter,inside diameter,total wall thickness,reinforced wallthickness,liner thickness(where applicable),and length di-mensions of“fiberglass”(glass-fiber-reinforced thermosettingresin)pipe.Included are procedures for measuring tapereddimensions and taper angles for pipe intended to be joined bytapered socket fittings,and procedures for gaging internal andexternal threads.1.2 This practice also includes procedures for determiningdimensions for fiberglass pipe fittings.1.3 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are forinformation only.NOTE1There is no similar or equivalent ISO standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of whoever uses this standard to consult andestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D4166 Test Method for Measurement of Thickness of Non-magnetic Materials by Means of a Digital MagneticIntensity Instrument(Withdrawn 2008)32.2 ANSI Standard:B 2.1 Pipe Threads(Except Dryseal)42.3 API Standard:API 5BThreading,Gaging,and Thread Inspection ofCasing,Tubing,and Line Pipe Threads53.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 deviation from straightness the maximum deviationfrom a straight line exhibited by a pipe specimen divided by thelength of the specimen.3.1.2 fiberglass pipea tubular product containing glass-fiber 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.3.1.3 laying length of fittingsthe actual increase in thelength of a line afforded by the fitting when installed.3.1.4 liner and exterior surface layer thicknessesthe innerand outer portions of the wall used to enhance chemical andwater resistance;they may have a different composition thanthe reinforced wall and the thicknesses of these internal andexternal surfaces may be measured when their boundary limitsare visually indentifiable and if they are each at least 0.005 in.(0.10 mm)in thickness.3.1.5 reinforced thermosetting resin pipe(RTRP)a fiber-glass pipe without aggregate.3.1.6 reinforced wall thicknessthe total wall thicknessminus the liner or exterior surface layer thickness,or both.4.Significance and Use4.1 This practice provides for determining the physicaldimensions of fiberglass pipe and fittings.This practice is1This practice is under the jurisdiction ofASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.23 on Reinforced Plastic PipingSystems and Chemical Equipment.Current edition approved Dec.1,2011.Published March 2012.Originallyapproved in 1977.Last previous edition approved in 2006 as D3567 97(2006).DOI:10.1520/D3567-97R11.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from American Petroleum Institute(API),1220 L.St.,NW,Washington,DC 20005-4070,http:/api-ec.api.org.*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 suitable for determination of dimensional compliance withproduct specifications.5.Conditioning5.1 Test conditions for measurements shall be in accordancewith appropriate product specification(s).6.Total Wall ThicknessPipe and Fittings6.1 ApparatusCalipers,optical comparators described inSection 7,ultrasonic thickness meters,or other gages such asthe digital magnetic intensity instrument described by TestMethod D4166,with graduations of 0.01 in.(0.025 mm)or lessthat produces a thickness measuring accuracy of within 5%,may be used for measuring thicknesses of 0.20 in.(5.1 mm)orgreater.For thicknesses les
