Designation:D630021An American National StandardStandard Practice forDetermination of Precision and Bias Data for Use in TestMethods for Petroleum Products,Liquid Fuels,andLubricants1This standard is issued under the fixed designation D6300;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.INTRODUCTIONBoth Research Report RR:D02-1007,2Manual on Determining Precision Data for ASTM Methodson Petroleum Products and Lubricants2and the ISO 4259,benefitted greatly from more than 50 yearsof collaboration between ASTM and the Institute of Petroleum(IP)in the UK.The more recent workwas documented by the IP and has become ISO 4259.ISO 4259 encompasses both the determination of precision and the application of such precisiondata.In effect,it combines the type of information in RR:D02-10072regarding the determination ofthe precision estimates and the type of information in Practice D3244 for the utilization of test data.The following practice,intended to replace RR:D02-1007,2differs slightly from related portions of theISO standard.1.Scope*1.1 This practice covers the necessary preparations andplanning for the conduct of interlaboratory programs for thedevelopment of estimates of precision(determinability,repeatability,and reproducibility)and of bias(absolute andrelative),and further presents the standard phraseology forincorporating such information into standard test methods.1.2 This practice is generally limited to homogeneous pe-troleum products,liquid fuels,and lubricants with whichserious sampling problems(such as heterogeneity or instabil-ity)do not normally arise.1.3 This practice may not be suitable for products withsampling problems as described in 1.2,solid or semisolidproducts such as petroleum coke,industrial pitches,paraffinwaxes,greases,or solid lubricants when the heterogeneousproperties of the substances create sampling problems.In suchinstances,consult a trained statistician.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:3D3244 Practice for Utilization of Test Data to DetermineConformance with SpecificationsD3606 Test Method for Determination of Benzene andToluene in Spark Ignition Fuels by Gas ChromatographyD6708 Practice for Statistical Assessment and Improvementof Expected Agreement Between Two Test Methods thatPurport to Measure the Same Property of a MaterialD7915 Practice for Application of Generalized ExtremeStudentized Deviate(GESD)Technique to Simultane-ously Identify Multiple Outliers in a Data SetE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE456 Terminology Relating to Quality and StatisticsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricantsand is the direct responsibility of Subcom-mittee D02.94 on Coordinating Subcommittee on Quality Assurance and Statistics.Current edition approved May 1,2021.Published May 2021.Originallyapproved in 1998.Last previous edition approved in 2020 as D6300 20b DOI:10.1520/D6300-21.2Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D02-1007.ContactASTM CustomerService at serviceastm.org.3For 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.*A Summary of Changes section appears at the end of this standardCopyright 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.12.2 ISO Standards:ISO 4259 Petroleum Products-Determination and Applica-tion of Precision Data in Relation to Methods of Test43.Terminology3.1 Definitions:3.1.1 analysis of variance(ANOVA),ntechnique that en-ables the total variance of a method to be broken down into itscomponent factors.ISO 42593.1.2 bias,nthe difference between the expectation of thetest results and an accepted
