Designation:D85817Standard Test Methods forManganese in Water1This standard is issued under the fixed designation D858;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 These test methods cover the atomic absorption deter-mination of dissolved and total recoverable manganese inwater and certain wastewaters.Section 34 on Quality Controlpertains to these test methods.Three test methods are given asfollows:Test MethodConcentration RangeSectionsAAtomic Absorption,Direct0.1 to 5 mg/L7 to 15BAtomic Absorption,Chelation-Extraction10 to 500 g/L16 to 24CAtomic Absorption,Graphite Furnace5 to 50 g/L25 to 331.2 Test Methods A,B,and C were used successfully onreagent grade and natural waters.Other matrices used in thestudy were brine(Test Method B),effluent from a woodtreatment plant,and condensate from a medium BTU coalgasification process(Test Method C).It is the users responsi-bility to ensure the validity of a test method for waters ofuntested matrices.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversion to inch-pound units that are provided for informa-tion only and are not considered standard.1.4This 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 and health practices and determine the applica-bility of regulatory limitations prior to use.For specific hazardstatements,see 11.7,20.2,20.9,and 22.11.1.5 Former Test MethodA(Colorimetric)was discontinued.For historical information,see Appendix X1.1.6 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:2D1066 Practice for Sampling SteamD1068 Test Methods for Iron in WaterD1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD1687 Test Methods for Chromium in WaterD1688 Test Methods for Copper in WaterD1691 Test Methods for Zinc in WaterD1886 Test Methods for Nickel in WaterD1976 Test Method for Elements in Water by Inductively-Coupled Argon Plasma Atomic Emission SpectroscopyD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on WaterD3370 Practices for Sampling Water from Closed ConduitsD3557 Test Methods for Cadmium in WaterD3558 Test Methods for Cobalt in WaterD3559 Test Methods for Lead in WaterD3919 Practice for Measuring Trace Elements in Water byGraphite Furnace Atomic Absorption SpectrophotometryD4841 Practice for Estimation of Holding Time for WaterSamples Containing Organic and Inorganic ConstituentsD5673 Test Method for Elements in Water by InductivelyCoupled PlasmaMass SpectrometryD5810 Guide for Spiking into Aqueous SamplesD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water Analysis3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this standard,refer toTerminology D1129.1These test methods are under the jurisdiction of ASTM Committee D19 onWater and are the direct responsibility of Subcommittee D19.05 on InorganicConstituents in Water.Current edition approved June 1,2017.Published June 2017.Originallyapproved in 1945.Last previous edition approved in 2012 as D858 12.DOI:10.1520/D0858-17.2For 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 3.2 Definitions of Terms Specific to This Standard:3.2.1continuing calibration blank,na solution contain-ing no analytes(of interest)which is used to verify blankresponse and freedom from carryover.3.2.2 continuing calibration verification,na solution(orset of solutions)of known concentration used to verify freedomfrom excessive instrumental drift;the concentration is to coverthe range of calibration curve.3.2.3 t
