Designation:D782518Standard Practice forGenerating a Process Stream Property Value throughApplication of a Process Stream Analyzer1This standard is issued under the fixed designation D7825;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.Scope*1.1 This practice covers generating a Process Stream Prop-erty Value(PSPV)from the application of a process streamanalyzer,which requires the use of several ASTM standards.These standards describe procedures to collect a representativesample,establish and validate the relationship to the primarytest method,and calculate a property value with an expecteduncertainty.Each standard builds or prepares data,or both,tobe used in another standard.The workflow process culminatesto produce a process stream analyzer result that represents auser defined batch of product.The sequence in which thestandards are to be utilized is defined in this practice.1.2 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.1.3 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:2D3764 Practice for Validation of the Performance of ProcessStream Analyzer SystemsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6122 Practice for Validation of the Performance of Multi-variate Online,At-Line,and Laboratory Infrared Spectro-photometer Based Analyzer SystemsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6624 Practice for Determining a Flow-Proportioned Aver-age Property Value(FPAPV)for a Collected Batch ofProcess Stream Material Using Stream Analyzer DataD6708 Practice for Statistical Assessment and Improvementof Expected Agreement Between Two Test Methods thatPurport to Measure the Same Property of a MaterialD7235 Guide for Establishing a Linear Correlation Relation-ship Between Analyzer and Primary Test Method ResultsUsing Relevant ASTM Standard PracticesD7278 Guide for Prediction ofAnalyzer Sample System LagTimesD7453 Practice for Sampling of Petroleum Products forAnalysis by Process Stream Analyzers and for ProcessStream Analyzer System ValidationD7808 Practice for Determining the Site Precision of aProcess Stream Analyzer on Process Stream MaterialE1655 Practices for Infrared Multivariate QuantitativeAnalysisE2617 Practice for Validation of Empirically Derived Mul-tivariate Calibrations3.Terminology3.1 DefinitionsPlease refer to the individually citedASTM standards for definitions.3.2 Acronyms:3.2.1 FPAPV(s)Flow Proportional Average Property Val-ue(s)3.2.2 MLRMultilinear Regression3.2.3 PCRPrincipal Components Regression3.2.4 PLSPartial Least Squares3.2.5 PSPV(s)Process Stream Property Value(s)3.2.6 PTMPrimary Test Method3.2.7 PTMR(s)Primary Test Method Result(s)3.2.8 PPTMR(s)Predicted Primary Test Method Result(s)3.2.9 QCQuality Control3.2.10 UAR(s)Uncorrected Analyzer Result(s)1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.25 on Performance Assessment and Validation of Process StreamAnalyzer Systems.Current edition approved Oct.1,2018.Published October 2018.Originallyapproved in 2012.Last previous edition approved in 2012 as D7825 12.DOI:10.1520/D7825-18.2For 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.*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.1 4.Significance and Use4.1 The standards employed in the Process StreamAnalyzerPSPV Generation Flow Diagram each have a specific deliver-able that when combined into a single system produces a PSPVenabling the representation of pro
