Designation:D842821Standard Guide forEstablishing Analyst Competence to Perform a Test Method1This standard is issued under the fixed designation D8428;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 guide covers general guidance on assessing thecompetence of an analyst to perform a specific test method fora specific product or set of products(for example,lightdistillates).It also provides guidance on some of the possibleapproaches that may be taken to perform the assessment.1.2 This guide is intended for the establishment of compe-tence for the entire performance of a test method(that is,sample preparation,instrument set up,preparation of standardsand reagents,performance of the test method,calculations,etc.)or the establishment of competence may be limited to aspecific aspect in the performance of a test method(forexample,sample preparation).1.3 The establishment of analyst competence should only beperformed if the laboratory itself is capable of performing thetest in strict conformance with the test method(that is,has theequipment,standards and reagents,materials,etc.which meettest method requirements).1.4 This guide does not cover training of an analyst,otherthan a review of training records to indicate the analyst hasbeen trained.1.5 This guide does not cover the establishment of generaltechnical competence of an analyst.1.6 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.1.7 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:2D6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6792 Practice for Quality Management Systems in Petro-leum Products,Liquid Fuels,and Lubricants TestingLaboratoriesD7372 Guide for Analysis and Interpretation of ProficiencyTest Program ResultsE456 Terminology Relating to Quality and Statistics2.2 ISO Standards:3ISO Guide 30 Reference materials-Selected terms anddefinitionsISO/IEC 17025 General Requirements for the Competenceof Testing and Calibration LaboratoriesISO 17034 General Requirements for the Competence ofReference Material ProducersANSI/ISO/ASQ Q9000 Quality Management System Stan-dards2.3 Other Standards:AASHTO R-18 Standard Recommended Practice for Estab-lishing and Implementing a Quality Management Systemfor Construction Materials Testing Laboratories43.Terminology3.1 Definitions:3.1.1 accepted reference value,ARV,na value that servesas an agreed upon reference for comparison,and which isderived as:(1)a theoretical or established value,based onscientific principles,(2)an assigned value,based on experi-mental work of some national or international organizationsuch as the U.S.National Institute of Standards and Technol-ogy(NIST),or(3)a consensus value,based on collaborative1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.94.01 on Task Group A:Quality Assurance and Quality Control.Current edition approved Dec.1,2021.Published January 2022.DOI:10.1520/D8428-21.2For 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.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,https:/www.iso.org.4Available from American Association of State Highway and TransportationOfficials(AASHTO),444 N.Capitol St.,NW,Suite 249,Washington,DC 20001,http:/www.transportation.org.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.1experimental work under the auspices of a scientific orengineering group.E4563.1.2 calibration standard,na material with a certifiedvalue
