Designation:D215213Standard Test Method forAdequacy of Fusion of Extruded Poly(Vinyl Chloride)(PVC)Pipe and Molded Fittings by Acetone Immersion1This standard is issued under the fixed designation D2152;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 test method covers the determination of the ad-equacy of fusion of extruded rigid poly(vinyl chloride)(PVC)pipe and molded fittings as indicated by reaction to immersionin anhydrous acetone.1.2 The values stated in inch-pound units are to be regardedas the standard except where instruments are calibrated in SIunits.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.Specific hazardsstatements are given in Annex A1.2.Referenced Documents2.1 ASTM Standards:2D618 Practice for Conditioning Plastics for Testing3.Significance and Use3.1 This test method is applicable only for distinguishingbetween inadequately fused and adequately fused PVC.Thedifference between thermally degraded and adequately fusedPVC cannot be detected by this test method.Acetone immer-sion is not a substitute for burst,impact,or other physical orchemical tests on PVC pipe or fittings and it,therefore,shallnot be used as the only test specification for purchasing of PVCpipe and fittings.This test only detects inadequate fusion anddoes not determine the over-all quality of the PVC pipe orfittings.3.2 This test method is useful in determining whetherinadequate fusion contributed to failure of PVC pipe or fittingsin other physical or chemical tests,or in service.3.3 This test method is useful in evaluating the adequacy ofPVC fusion obtained in process or materials trials.3.4 This test method determines adequacy of fusion on asingle,relatively small specimen.This test method requires theuse of a hazardous reagent which must be properly handled anddisposed.Therefore,this test method may not be cost-effectiveto employ as a routine quality control test.4.Apparatus4.1 ContainerEither individual,sealable containers foreach specimen or one large,airtight container capable ofholding several specimens without touching one another.4.2 Hydrometer and CylinderPrecision hydrometer,graduated in thousandths,with a minimum range of 0.780 to0.790 g/mL and a cylinder large enough to immerse thehydrometer.4.3 ThermometerASTM12Ctotalimmersionthermometer,range from 20C to 102C accurate to 0.2C,orequivalent.5.Reagent5.1 AcetoneAmerican Chemical Society Reagent Grade,having a maximum density of 0.7857 g/mL at 25C.NOTE1See AnnexA1 for the safety and health precautions to be usedwith acetone.5.2 Prior to conducting the test,check the density of theacetone with a precision hydrometer to determine its dryness.If the density of the acetone is greater than 0.7890 g/mL at23C,(corresponding to approximately 1%water by mass(seeFig.X1.1),use fresh acetone or dry the wet acetone with adrying agent.Recheck the density of the fresh or dried acetonebefore using.NOTE2Wet acetone can be dried by thoroughly agitating it with atleast 15 g of anhydrous calcium sulfate(CaSO4)for each gram of waterpresent.NOTE3The presence of water in the acetone reduces its sensitivity todifferences in the degree of fusion of rigid poly(vinyl chloride)(PVC).Itis important to dry the acetone properly and conduct the test in a sealed1This test method is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.25 on VinylBased Pipe.Current edition approved May 1,2013.Published June 2013.Originallyapproved in 1963T.Last previous edition approved in 2010 as D2152 95(2010).DOI:10.1520/D2152-13.2For 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 container,because acetone rapidly absorbs moisture from the atmosphere.NOTE4Round-robin testing between four laboratories showed thattest results are not significantly altered with up to 2%water by weight inthe acetone.6.Sampling6.1 Specimens shall be taken from individual pipe sections,fittings,or remnant portions of pipe or fittings.Specimens shallbe taken from locations which are to be evaluated for adequacyof fusion,or immediately adjacent to them.6.2 The number of individual specimens to be tested andtheir locations shall
