Designation:D80202(Reapproved 2013)Standard Test Methods forSampling and Testing Pine Oils1This standard is issued under the fixed designation D802;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.Scope1.1 These test methods cover procedures for sampling andtesting pine oils,and are applicable to both natural pine oilsderived from pine stumps either by the steam and solventprocess or by destructive distillation,and also to synthetic pineoils obtained by the chemical hydration of terpene hydrocar-bons.1.2 The procedures given in these test methods appear in thefollowing order:SectionSampling4Appearance5Color6Specific Gravity7Refractive Index8Composition9Moisture101.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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:2D268 Guide for Sampling and Testing Volatile Solvents andChemical Intermediates for Use in Paint and RelatedCoatings and MaterialD803 Test Methods for Testing Tall OilD890 Test Method for Water in Liquid Pine ChemicalsD1209 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-phyE300 Practice for Sampling Industrial Chemicals3.Significance and Use3.1 The testing procedures described in these test methodshave been in use for many years and emphasize the physicalproperties of pine oil rather than its chemical composition.TestMethods D6387 describe a capillary gas chromatographymethod which is suitable for determining both the major andminor components found in pine oils.4.Sampling4.1 Sample the material in accordance with the proceduredescribed in Guide D268 and Practice E300.5.Appearance5.1 Examine a portion of the sample after agitation todetermine its clarity and freedom from foreign matter andseparated water.6.Color6.1 Compare the color of the sample in any suitable ordesignated apparatus with the accepted or specific colorstandard.Accepted color standards are the Gardner color scalefound in Test Method D6166 and the platinum-cobalt scalefound in Test Method D1209.7.Specific Gravity7.1 Determine the specific gravity at 15.6/15.6C by anyconvenient method,reporting the value to the nearest 0.0005.(A pycnometer or specific gravity balance is recommended.Ahydrometer should not be used,on account of errors caused bysurface tension on the hydrometer stem.)Correct determina-tions made at any other temperature,using apparatus standard-ized at 15.6C by adding to or subtracting from the observedreading 0.00080 for each degree Celsius that the temperature ofthe liquid is above or below 15.6C.1These 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 June 1,2013.Published June 2013.Originallyapproved in 1944.Last previous edition approved in 2009 as D802 02(2009).DOI:10.1520/D0802-02R13.2For 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 8.Refractive Index8.1 Determine the refractive index with an instrument hav-ing a resolution of 60.0001 at 20C,if possible.If tested at anyother temperature,correct the reading obtained to 20C byadding or subtracting 0.00045 for each degree Celsius that thetemperature at which the determination was made is,respectively,above or below 20C.9.Composition9.1 Determine the component concentration of pine oil byusing the referenced method(Test Methods D6387)whichemploys a capillary column technology.10.Moisture10.1 The recommended method for measuring the moisturecontent of pine oil is the use of the Karl Fischer reagent and isdescribed in Test Method D890.This test method is more rapidand more reliable than the alternative method described in10.2.10.2 Alternative Method,Distillation:10.2.1 The azeoitropic distillation method described in theprocedure section of Test Methods D803 can be used formoisture analysis of pine oil.NOTE1It is important that the flask be
