Designation:D23313Standard Test Methods ofSampling and Testing Turpentine1This standard is issued under the fixed designation D233;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 These test methods cover procedures for sampling andtesting turpentine,as defined by the Code of Federal Regula-tions and Terminology D804.These test methods are also usedfor the sampling and testing of pinenes,the major componentsof most turpentines.1.2 These test methods primarily measure the physicalrather than the chemical properties of turpentines and pinenes.As turpentines and pinenes are currently used chiefly aschemical raw materials for the production of resins andsynthetic organic chemicals,chemical composition is also veryimportant.Consequently,testing the chemical composition ofturpentines and pinenes by gas chromatography has displacedthese test methods to a large extent.(See for example TestMethods D6387.)1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 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.2.Referenced Documents2.1 ASTM Standards:2D86 Test Method for Distillation of Petroleum Products atAtmospheric PressureD270 Methods of Sampling Petroleum and Petroleum Prod-ucts(Withdrawn 1984)3D804 Terminology Relating to Pine Chemicals,IncludingTall Oil and Related ProductsD1193 Specification for Reagent WaterD1209 Test Method for Color of Clear Liquids(Platinum-Cobalt Scale)D6166 Test Method for Color of Pine Chemicals and Re-lated Products(Instrumental Determination of GardnerColor)D6387 Test Methods for Composition of Turpentine andRelated Terpene Products by Capillary Gas Chromatogra-phyE1 Specification for ASTM Liquid-in-Glass Thermometers2.2 Other Document:Code of Federal Regulations,Title 7,Part 160“Regulationsand Standards for Naval Stores,”199943.Significance and Use3.1 The test procedures described in this standard weredeveloped when the chief use for turpentine was as a solvent.Currently however,the chief use for turpentine(and pinenes)isas raw materials for the production of resins and syntheticorganic chemicals.Thus the chemical composition of turpen-tines and pinenes is extremely important and tests,in additionto the ones described in these test methods,are required inorder to fully characterize turpentines and pinenes.The mostwidely used technique for determining the chemical composi-tion of turpentines(and pinenes)is gas chromatography(seeTest Methods D6387).4.Purity of Reagents4.1 Reagent grade chemicals shall be used in all tests.Unless otherwise indicated,it is intended that all reagents shallconform to the specifications of the Committee on AnalyticalReagents of the American Chemical Society,where such1These test methods are under the jurisdiction of ASTM Committee D01 onPaint and Related Coatings,Materials,and Applications and are the directresponsibility of Subcommittee D01.34 on Pine Chemicals and HydrocarbonResins.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1926.Last previous edition approved in 2012 as D233 12.DOI:10.1520/D0233-13.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 specifications are available.5Other grades may be used,pro-vided it is first ascertained that the reagent is of sufficientlyhigh purity to permit its use without lessening the accuracy ofthe determination.4.2 Unless otherwise indicated,references to water shall beunderstood to mean reagent water conforming to SpecificationD1193.SAMPLING5.Sampling5.1 The method of sampling specified in 5.2 or 5.3 shall beused,according to the special conditions that apply.5.2 From Loaded Tank Car or Other Large VesselThecomposite sample taken shall be not less than12gal(1.9 L)andshould consist of small samples of not more than 1 qt(0.9 L)each,taken fro
