Designation:D744816Standard Practice forEstablishing the Competence of Laboratories Using ASTMProcedures in the Sampling and Analysis of Coal and Coke1This standard is issued under the fixed designation D7448;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 practice specifies requirements to operate andevaluate the quality and management systems in a laboratorythat provides services with respect to sample collection,samplepreparation,or testing of coal,coke,and ash derived from coalor coke usingASTM standards that are under the jurisdiction ofCommittee D05 on Coal and Coke.NOTE1The word“laboratory”is used throughout this practice whenreferring to an organization that provides services in coal sampling ortesting,or both.It is recognized,however,that the word may not beappropriate to an organization that does not perform actual laboratorysample testing.1.2 International standardANSI/ISO/IEC 17025 shall be thegoverning document specifying requirements for management,technical competence and evaluation of a laboratory.NOTE2An accrediting body or user of laboratory services can alsoimpose technical or non-technical requirements not specifically addressedin ANSI/ISO/IEC 17025 provided they do not invalidate the requirementsof ANSI/ISO/IEC 17025.1.3 This practice is used to evaluate only those capabilitiesspecifically claimed by a laboratory.1.4 All percentages are percent mass fractions unless other-wise noted.1.5 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:2D121 Terminology of Coal and CokeD3174 Test Method for Ash in the Analysis Sample of Coaland Coke from CoalD4239 Test Method for Sulfur in the Analysis Sample ofCoal and Coke Using High-Temperature Tube FurnaceCombustionD4749 Test Method for Performing the Sieve Analysis ofCoal and Designating Coal SizeD5061 Test Method for Microscopical Determination of theTextural Components of Metallurgical CokeD5515 Test Method for Determination of the SwellingProperties of Bituminous Coal Using a DilatometerD6172 Test Method for Determining the Volume of BulkMaterials Using Contours or Cross Sections Created byDirect Operator Compilation Using Photogrammetric Pro-ceduresE2554 Practice for Estimating and Monitoring the Uncer-tainty of Test Results of a Test Method Using ControlChart Techniques2.2 ANSI/ISO/IEC Document:317025 General Requirements for the Competence of Cali-bration and Testing Laboratories2.3 ISO Documents:45725-3 Accuracy(Trueness and Precision)of MeasurementMethods and ResultsPart 3:Intermediate Measures ofPrecision of a Standard Measurement Method5725-6 Accuracy(Trueness and Precision)of MeasurementMethods and ResultsPart 6:Use in Practice ofAccuracyValues3.Significance and Use3.1 International standard ANSI/ISO/IEC 17025 promotesthe use of documented accountability and quality controlprocedures to assure a laboratory and its clients that thelaboratory can produce technically valid data and results in theroutine performance of its sampling,sample preparation andtesting activities.3.2 A laboratory shall use ANSI/ISO/IEC 17025 to developits quality system.Clause 4 of ANSI/ISO/IEC 17025 specifiesthe requirements for sound management.Clause 5 of ANSI/1This practice is under the jurisdiction of ASTM Committee D05 on Coal andCoke and is the direct responsibility of Subcommittee D05.24 on Statistics.Current edition approved March 1,2016.Published April 2016.Originallyapproved in 2009.Last previous edition approved in 2009 as D7448-09.DOI:10.1520/D7448-16.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 ISO/IEC 17025 specifies the requirements for technical com-petence for the type of tests or calibrations,or both thelaboratory undertakes.3.3 In addition to complying with the requirements ofANSI/ISO/IEC 17025,the Annex of this standard practicecontains information that shall be considered important for theevaluation and operation of a competent Coal and
