1、Designation:D119306(Reapproved 2011)Federal Test MethodStandard No.7916Standard Specification forReagent Water1This standard is issued under the fixed designation D1193;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last
2、 revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification describes the required char
3、acteristicsof waters deemed suitable for use with the Standards under thejurisdiction of ASTM.1.2 The alphanumeric characters ascribed to water types andgrades are specified in the ASTM Format and Style Manual.These have been assigned in order of historical precedence andshould not be taken as an in
4、dication of a progression in waterpurity.1.3 Four types of waters have been specified,with threeadditional grades that can be applied to the four types.Thegrade specifications specifically address contaminants of mi-crobiological origin.1.4 All applicable ASTM Standards are expected to refer-ence on
5、e or more of these reagent water types where reagentwater is needed as a component of an analytical measurementprocess.Where a different water type or grade is needed for anASTM Standard,it may be added to this Specification throughthe ASTM Standard revision process.1.5 Although these water types an
6、d associated grades havebeen defined specifically for use with ASTM Standards,theymay be appropriate for other applications.It is the responsi-bility of the users of this standard to ensure that the selectedwater types or grades are suitable for their intended use.Historically,reagent water Types I,
7、II,III,and IV have beenlinked to specific processes for their production.Starting withthis revision,these types of waters may be produced withalternate technologies as long as the appropriate constituentspecifications are met and that water so produced has beenshown to be appropriate for the applica
8、tion where the use ofsuch water is specified.Therefore,the selection of an alternatetechnology in place of the technology specified in Table 1should be made taking into account the potential impact ofother contaminants such as microorganism and pyrogens.Suchcontaminants were not necessarily consider
9、ed by the perfor-mance characteristics of the technology previously specified.1.6 Guidance for applications,the preparation,use andmonitoring,storage,handling,distribution,testing of thesespecified waters and validation of the water purification systemis provided in Appendix X1 of this document.1.7T
10、he values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.8 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
