1、Designation:D584722Standard Practice forWriting Quality Control Specifications for Standard TestMethods for Water Analysis1This standard is issued under the fixed designation D5847;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、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 provides specific,mandatory requirementsfor incorporating quality control(QC)procedures into all tes
3、tmethods under the jurisdiction of Committee D19.1.2 ASTM International has adopted the following:Policy on implementation of requirements for a quality controlsection in standard test methods generated by Committee D19on Water.GENERALBy July 29,1998,or at the next reapproval or revision,whichever i
4、s later,every D19 Standard Test Method shall contain aQC section that is in full compliance with the requirements of thispractice.NEW COLLABORATIVE TESTINGAs of July 29,1998,eachcollaborative study design shall include a QC section as part of themethod to be tested.Prior to approval of the study des
5、ign,theResults Advisor or equivalent shall ascertain the appropriateness ofthe QC section in meeting the requirements of this practice andPractice D2777,and shall advise the designer of the study of anychanges needed to fulfill the requirements of these practices.Beforea collaborative study may be c
6、onducted,approval of the study de-sign by the Results Advisor or equivalent shall be obtained.OLDER VALIDATED METHODSStandard test methods that werevalidated using Practices D2777 77,D2777 86,or D2777 94,when balloted for reapproval or revision,shall contain a QC sectionbased upon the best informati
7、on from the historical record.Whereappropriate,information derived from the record of the collaborativestudy shall be utilized for this purpose.The introduction of the QCsection into these standard test methods shall not be construed as arequirement for a new collaborative study,though the Subcommit
8、teemay opt for such a study.Any information available regarding QC orprecision/bias testing shall be included in the appropriate sections ofthe published test method.1.3 Required QC sections in all applicable test methods areintended to achieve two goals.First,users of Committee D19test methods will
9、 be able to demonstrate a minimum compe-tency in the performance of these test methods by comparisonwith collaborative study data.Second,all users of test methodswill be required to perform a minimum level of QC as part ofproper implementation of these test methods to ensure ongoingcompetency.1.4 Th
10、is practice contains the primary requirements for QCof a specific test method.In many cases,it may be desirable toimplement additional QC requirements to assure the desiredquality of data.1.5 The specific requirements in this practice may not beapplicable to all test methods.These requirements may v
11、arydepending on the type of test method used as well as theanalyte being determined and the sample matrix being ana-lyzed.1.5.1 If there are compelling reasons why any of the specificQC requirements listed in this practice are not applicable to aspecific test method,these reasons shall be documented
12、 in theQC section of the test method.1.5.2 With the approval of Committee D19 on the recom-mendation of the D19 Results Advisor or equivalent and theTechnical Operations section of the Executive Subcommittee,astatement giving the compelling reasons why compliance withall or specific points of this p
13、ractice cannot be achieved willmeet the requirements of both ASTM and this practice.1.6 This practice is for use with quantitative test methodsand may not be applicable to qualitative test methods.1.7 Presently,this practice is applicable primarily to chemi-cal test methods.It is intended that,in fu
14、ture revisions,thepractice will be expanded to include other test methods such asmicrobiological test methods.1.8 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.9 This international standard was developed in accor-dance w
