2、 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 provides specific,mandatory requirementsfor incorporating quality control(QC)procedu
3、res into all testmethods under the jurisdiction of Committee D-19.1.2 ASTM has adopted the following:Policy on implementation of requirements for a quality controlsection in standard test methods generated by Committee D-19on Water.GENERALBy July 29,1998,or at the next reapproval or revision,whichev
4、er is later,every D-19 Standard Test Method shall contain aQC section that is in full compliance with the requirements of thispractice.NEW COLLABORATIVE TESTING As of July 29,1998,eachcollaborative study design shall include a QC section as part of themethod to be tested.Prior to approval of the stu
5、dy design,theResults Advisor shall ascertain the appropriateness of the QCsection in meeting the requirements of this Practice and PracticeD2777,and shall advise the designer of the study of any changesneeded to fulfill the requirements of these practices.Before a collab-orative study may be conduct
6、ed,approval of the study design by theResults Advisor must be obtained.OLDER VALIDATED METHODS Standard test methods that werevalidated using D-2777-77,D-2777-86,or D-2777-94,when ballottedfor reapproval or revision,shall contain a QC section based upon thebest information from the historical record
7、.Where appropriate,infor-mation derived from the record of the collaborative study shall beutilized for this purpose.The introduction of the QC section intothese standard test methods shall not be construed as a requirementfor a new collaborative study,though the Subcommittee may opt forsuch a study
8、.Any information available regarding QC or precision/bias testing shall be included in the appropriate sections of the pub-lished method.1.3 Required QC sections in all applicable test methods areintended to achieve two goals.First,users of Committee D-19test methods will be able to demonstrate a mi
9、nimum 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 This practice contains the pri
10、mary 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 varydepending on the type of
11、test method used as well as theanalyte being determined and the sample matrix being ana-lyzed.See Explanation 1 in Appendix X1.1.5.1 If there are compelling reasons why any of the specificQC requirements listed in this practice are not applicable to aspecific test method,these reasons must be docume
12、nted in theQC section of the test method.1.5.2 With the approval of Committee D-19 on the recom-mendation of the D-19 Results Advisor and the TechnicalOperations section of the Executive Subcommittee,a statementgiving the compelling reasons why compliance with all orspecific points of this practice
13、cannot be achieved will meet therequirements of both ASTM and this practice.1.5.3 Test Methods developed prior to the approval of thispractice with a QC Section that meet the requirements ofSpecification D5789 are considered in compliance with thisPractice.1.6 This practice is for use with quantitat
14、ive methods andmay 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 future revisions,thepractice will be expanded to include other methods such asmicrobiological methods.2.Referenced Documents2.1 ASTM S
