Designation:C61314Standard Test Method forConstituent Content of Composite Prepreg by SoxhletExtraction1This standard is issued under the fixed designation C613;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 test method covers a Soxhlet extraction procedureto determine the matrix content,reinforcement content,andfiller content of composite material prepreg.Volatiles content,if appropriate,and required,is determined by means of TestMethod D3530.1.1.1 The reinforcement and filler must be substantiallyinsoluble in the selected extraction reagent and any filler mustbe capable of being separated from the reinforcement byfiltering the extraction residue.1.1.2 Reinforcement and filler content test results are totalreinforcement content and total filler content;hybrid materialsystems with more than one type of either reinforcement orfiller cannot be distinguished.1.2 This test method focuses on thermosetting matrix ma-terial systems for which the matrix may be extracted by anorganic solvent.However,other,unspecified,reagents may beused with this test method to extract other matrix material typesfor the same purposes.1.3 Alternate techniques for determining matrix and rein-forcement content include Test Methods D3171(matrixdigestion),D2584(matrix burn-off/ignition),and D3529M(matrix dissolution and ignition loss).Test Method D2584 ispreferred for reinforcement materials,such as glass,quartz,orsilica,that are unaffected by high-temperature environments.1.4 The technical content of this standard has been stablesince 1997 without significant objection from its stakeholders.As there is limited technical support for the maintenance of thisstandard,changes since that date have been limited to itemsrequired to retain consistency with other ASTM D30 Commit-tee standards.The standard therefore should not be consideredto include any significant changes in approach and practicesince 1997.Future maintenance of the standard will only be inresponse to specific requests and performed only as technicalsupport allows.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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 precau-tionary statements are given in Section 9 and 7.2.3 and 8.2.1.2.Referenced Documents2.1 ASTM Standards:2D883 Terminology Relating to PlasticsD2584 Test Method for Ignition Loss of Cured ReinforcedResinsD3171 Test Methods for Constituent Content of CompositeMaterialsD3529M Test Methods for Constituent Content of Compos-ite PrepregD3530 Test Method for Volatiles Content of CompositeMaterial PrepregD3878 Terminology for Composite MaterialsE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE456 Terminology Relating to Quality and StatisticsE1309 GuideforIdentificationofFiber-ReinforcedPolymer-Matrix Composite Materials in DatabasesE1471 Guide for Identification of Fibers,Fillers,and CoreMaterials in Computerized Material Property Databases1This test method is under the jurisdiction of ASTM Committee D30 onComposite Materials and is the direct responsibility of Subcommittee D30.03 onConstituent/Precursor Properties.Current edition approved Oct.15,2014.Published November 2014.Originallyapproved in 1967.Last previous edition approved in 2003 as C613 97(2003)2.DOI:10.1520/C0613-14.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 NFPA Standard:NFPA 86 Standard for Ovens and Furnaces33.Terminology3.1 DefinitionsTerminology D3878 defines terms relatingto composite materials.Terminology D883 defines termsrelating to plastics.Terminology E456 and Practice E177define terms relating to statistics.In the event of a conflictbetween terms,Terminology D3878 shall have precedenceover the other documents.3.2 Definitions of Terms Specific to This Standard:3.2.1 dry resin content,nprepreg resin content calculatedby subtracting the average mass loss due to volatiles from theinitial test specimen mass.3.2.2 filler content,nthe amount of filler presen
