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 U.S.Department of Defense.1.Scope1.1 This specification describes the required
3、characteristicsof 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 manual,Form and Style for ASTMStandards.These have been assigned in order of historicalprecedence and should not be
4、 taken as an indication of aprogression in water purity.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 t
5、o refer-ence one 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
6、 water types and 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 specification to ensure that theselected water types or grades are suitable for their intendeduse.Historically,rea
