Designation:D80315Standard Test Methods forTesting Tall Oil1This standard is issued under the fixed designation D803;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 the test procedures to beapplied to whole tall oils or refined tall oils.Previous editionsof these test methods have described test procedures that areused to test tall oil fatty acid,rosin,and other tall oil-derivedproducts as well as test crude and refined tall oil.Consequently,these test methods are widely cited in reference books andindustry literature for the testing of tall oil-derived products.1.1.1 In this current revision,procedural details of some ofthe often-cited test methods have been removed and the testmethods consolidated with other existing test methods.In suchcases the consolidated methods,applicable to all tall oil-derived products.1.2 The procedures appear in the following order:Physical TestsSectionsViscosity:Rotational Viscometer Method(Preferred Method)7Bubble Time Method8Flash Point9Color10Moisture:11Insoluble Matter12Ash13Chemical AnalysisAcid Number16Saponification Number17Rosin Acids18Unsaponifiable Matter19Fatty Acids201.3 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:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD269 Test Method for Insoluble Matter in Rosin and RosinDerivativesD464 Test Methods for Saponification Number of NavalStore Products Including Tall Oil and Other RelatedProductsD465 Test Methods for Acid Number of Naval StoresProducts Including Tall Oil and Other Related ProductsD890 Test Method for Water in Liquid Pine ChemicalsD1065 Test Method for Unsaponifiable Matter in NavalStores,Including Rosin,Tall Oil,and Related ProductsD1240 Test Methods for Rosin Acids Content of PineChemicals,Including Rosin,Tall Oil,and Related Prod-uctsD1466 Test Method for Sampling Liquid Oils and FattyAcids Commonly Used in Paints,Varnishes,and RelatedMaterials(Withdrawn 2003)3D1544 Test Method for Color of Transparent Liquids(Gard-ner Color Scale)D1545 Test Method for Viscosity of Transparent Liquids byBubble Time MethodD1585 Test Methods for Fatty Acids Content of NavalStores,Including Rosin,Tall Oil,and Related ProductsD2196 Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational ViscometerD3278 Test Methods for Flash Point of Liquids by SmallScale Closed-Cup ApparatusD5974 Test Methods for Fatty and Rosin Acids in Tall OilFractionation Products by Capillary Gas ChromatographyD6166 Test Method for Color of Pine Chemicals and Re-lated Products(Instrumental Determination of GardnerColor)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 July 1,2015.Published July 2015.Originally approvedin 1944.Last previous edition approved in 2012 as D803 12.DOI:10.1520/D0803-15.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 E300 Practice for Sampling Industrial Chemicals3.Significance and Use3.1 Tall oil,both crude and refined,is an important by-product of the alkaline(kraft)pulping of pine wood.It consistsprimarily of fatty acids,resin acids,and neutral materials;thelevels of these various components depend on factors such asthe species of pine tree,geographic location,climate,etc.3.1.1 Tall oil is used primarily as a commercial source offatty acids and rosin,and,therefore,reliable methods for theanalysis of these components is necessary.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 suchspecifications are
