Designation:D 4182 97Standard Practice forEvaluation of Laboratories Using ASTM Procedures in theSampling and Analysis of Coal and Coke1This standard is issued under the fixed designation D 4182;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(e)indicates an editorial change since the last revision or reapproval.INTRODUCTIONTraditionally,coal testing facilities have been established to serve the specific interests or activitiesof one or more of the following:(1)Exploration and evaluation of coal fields.(2)Establishment of mining and coal preparation capabilities.(3)Coal quality evaluation:(a)to meet contractual obligations;(b)to determine compliance withmunicipal,state,and federal regulations;and(c)to generate documentation used to establish powerrates or rate basis.(4)Confirmation of properties pertinent to coal processing and utilization,such as direct combustionor the production of coal-derived products(for example,metallurgical coke,carbons,liquids,and gas).(5)Coal research pursuits.1.Scope1.1 This practice is limited to the evaluation of laboratoriesusing ASTM procedures that are under the jurisdiction ofCommittee D-5 on Coal and Coke.They may be used toevaluate a laboratorys capability to perform the functions forwhich it has been established.It is not the intention that thispractice be used to evaluate capabilities beyond those specifi-cally claimed by the laboratory.2.Referenced Documents2.1 ASTM Standards:D 346 Practice for Collection and Preparation of CokeSamples for Laboratory Analysis2D 409 Test Method for Grindability of Coal by theHardgrove-Machine Method2D 1989 Test Method for Gross Calorific Value of Coal andCoke by Microprocessor Controlled Isoperibol Calorim-eters2D 2013 Method of Preparing Coal Samples for Analysis2D 2234 Practice for Collection of a Gross Sample of Coal2D 2795 Test Methods for Analysis of Coal and Coke Ash2D 2961 Test Method for Total Moisture in Coal Reduced to2.36-mm(No.8)Mesh Top Sieve Size(Limited-PurposeMethod)2D 3173 Test Method for Moisture in theAnalysis Sample ofCoal and Coke2D 3174 Test Method forAsh in theAnalysis Sample of Coaland Coke from Coal2D 3175 Test Method for Volatile Matter in the AnalysisSample of Coal and Coke2D 3177 Test Methods for Total Sulfur in the AnalysisSample of Coal and Coke2D 3178 Test Methods for Carbon and Hydrogen in theAnalysis Sample of Coal and Coke2D 3179 Test Methods for Nitrogen in the Analysis Sampleof Coal and Coke2D 3286 Test Method for Gross Calorific Value of Coal andCoke by the Isoperibol Bomb Calorimeter2D 3302 Test Method for Total Moisture in Coal2D 3682 Test Method for Major and Minor Elements in Coaland Coke Ash by the Atomic Absorption Method2D 4239 Test Methods for Sulfur in the Analysis Sample ofCoal and Coke Using High Temperature Tube FurnaceCombustion Methods2D 4326 Test Method for Major and Minor Elements in Coaland Coke Ash by X-Ray Fluorescence21This practice is under the jurisdiction of ASTM Committee D-5 on Coal andCoke and is the direct responsibility of Subcommittee D05.30 on Accreditation.Current edition approved Sept.10,1997.Published May 1998.Originallypublished as D 4182 82.Last previous edition D 4182 92.2Annual Book of ASTM Standards,Vol 05.05.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.D 4621 Guide forAccountability and Quality Control in theCoal Analysis Laboratory2D 5142 Test Methods for the Proximate,Analysis of theAnalysis Sample of Coal and Coke by InstrumentalProcedures2D 5373 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Laboratory Samples ofCoal and Coke2D 5865 Test Method for Gross Calorific Value of Coal andCoke2E 548 Guide for General Criteria Used for EvaluatingLaboratory Competence3E 1187 Terminology Relating to Laboratory Accreditation3E 1267 Guide for ASTM Standard Specification QualityStatements4E 1323 Guide for Evaluating Laboratory MeasurementPractices and the StatisticalAnalysis of the Resulting Data33.Significance and Use3.1 This practice provides guidelines to be followed by anindividual or an accrediting body in evaluating a laboratoryscapability to perform those functions only for which thelaboratory claims competence.A laboratory for the purpose ofthis practice may be considered as any facility capable ofcarrying out one or more of the following functions relevant tocoal or coke,or both:3.1.1 Sampling,3.1.2 Sample preparation,3.1.3 Chemical analysis,and3.1.4 Physical testing.4.Functions4.1 The laboratory personnel should be able to demonstratea satisfactory knowledge of Practice D 2234 for coal orPractice D 346 for coke(or both),and the laboratory shouldhave the capability to perform sampling in accordance with theappropriate practice.4.2 The laboratory personnel should be able to demonstratea satisfactor
