Designation:D106518Standard Test Method forUnsaponifiable Matter in Pine Chemicals,Including Rosin,Tall Oil,and Related Products1This standard is issued under the fixed designation D1065;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 This test method covers the determination of the per-centage of material in pine chemicals products as defined inTerminology D804 including rosin,tall oil and relatedproducts,other than insoluble dirt or similar visible foreignmatter that does not yield a water-soluble soap when thesample is saponified with potassium hydroxide.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.NOTE1It has been reported that this method may not be applicable togum rosin,especially any gum rosin containing volatile terpenes.Volatileterpenes are by definition unsaponifiable matter,and can be lost under thedrying conditions described in 8.4.The method is applicable to tall oilrosin and wood rosin as these rosins do not contain volatile terpenes.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D509 Test Methods of Sampling and Grading RosinD803 Test Methods for Testing Tall OilD804 Terminology Relating to Pine Chemicals,IncludingTall Oil and Related ProductsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Significance and Use3.1 This test method is designed to broaden the scope of theprevious edition of the test method by the inclusion of tall oiland tall oil derived from products as test materials.TestMethods D803 currently includes a method for the determina-tion of unsaponifiable matter.3.2 The amount of unsaponifiable matter in tall oil and otherrelated products is important in characterizing such products asit indicates the level of nonacidic material,both free andcombined,present in the test material.The unsaponifiable innaval stores products is primarily composed of higher molecu-lar weight alcohols,sterols,and hydrocarbons.4.Apparatus4.1 Erlenmeyer or Other Flat-Bottom Flask,of 125-mL to250-mL capacity,with standard-taper 24/40 joint.4.2 Erlenmeyer Flask,of 250-mL to 300-mL capacity,withwide mouth.4.3 Separatory Funnels,of 300-mL to 500-mL capacity,with glass or polytetrafluoroethylene(PFTE)stoppers.4.4 Graduated Cylinder,one of 10 to 25-mL and one of 50to 100-mL capacity.4.5 Beaker,of up to 250-mL capacity.5.Reagents5.1 Purity of ReagentsReagent grade chemicals shall beused in all tests.Unless otherwise indicated,it is intended thatall reagents shall conform to the specifications of the Commit-tee on Analytical Reagents of the American Chemical Society,1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.34 on Pine Chemicals and Hydrocarbon Resins.Current edition approved July 1,2018.Published July 2018.Originally approvedin 1949.Last previous edition approved in 2014 as D1065 96(2014)1.DOI:10.1520/D1065-18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 where such specifications are available.3Other grades may beused,provided it is first ascertained that the reagent is ofsufficiently high purity to permit use without lessening theaccuracy of the determination.5.2 Purity of WaterUnless otherwise indicated,referencesto water shall be understood to mean distilled,or deionizedwater.6.Preparation of Sample6.1 Procurement and handling of s
