Designation:D546313Standard Guide forUse of Test Kits to Measure Inorganic Constituents inWater1This standard is issued under the fixed designation D5463;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.1.Scope*1.1 This guide covers general considerations for the use oftest kits for quantitative determination of analytes in water andwastewater.Test kits are available from various manufacturersfor the determination of a wide variety of analytes in drinkingwater,surface or ground waters,domestic and industrialfeedwaters and wastes,and water used in power generation andsteam raising.See Table 1 for a listing of some of the types ofkits that are available for various inorganic analytes in water.21.2 Ranges,detection limits,sensitivity,accuracy,and sus-ceptibility to interferences vary from kit to kit,depending onthe methodology selected by the manufacturer.In some cases,kits are designed to replicate exactly an official test method ofa standard-setting organization such as the Association ofOfficialAnalytical Chemists(AOAC),American Public HealthAssociation(APHA),ASTM,or the U.S.Environmental Pro-tection Agency(USEPA).In other cases,minor modificationsof official test methods are made for various reasons,such as toimprove performance,operator convenience,or ease of use.Adjustments may be made to sample size,reagent volumes andconcentrations,timing,and details of the analytical finish.Inyet other cases,major changes may be made to the official testmethod,such as the omission of analytical steps,change of theanalytical finish,omission of reagents,or substitution of onereagent for another.Reagents in test kits are often combined toobtain a fewer number and make the test easier to use.Additives may also be used to minimize interferences and tomake the reagent more stable with time.A kit test method maybe based on a completely different technology,not approved byany official or standard-setting organization.Combinations oftest kitsmulti-parameter test kitsmay be packaged tosatisfy the requirements of a particular application conve-niently.The test kits in such combination products may be usedto make dozens of determinations of several parameters.1.3 Test kit reagent refills are commonly available frommanufacturers.Refills permit cost savings through reuse of themajor test kit components.1.4 Because of the wide differences among kits and meth-odologies for different analytes,universal instructions cannotbe provided.Instead,the user should follow the instructionsprovided by the manufacturer of a particular kit.1.5 A test kit or kit component should not be used after themanufacturers expiration date;it is the users responsibility todetermine that the performance is satisfactory.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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 safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specificprecautionary statements,see Section 10.2.Referenced Documents2.1 ASTM Standards:3D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD3370 Practices for Sampling Water from Closed ConduitsD4453 Practice for Handling of High Purity Water SamplesD4691 Practice for Measuring Elements in Water by FlameAtomic Absorption SpectrophotometryD5810 Guide for Spiking into Aqueous SamplesD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water AnalysisE178 Practice for Dealing With Outlying ObservationsE275 Practice for Describing and Measuring Performance ofUltraviolet and Visible SpectrophotometersE958 Practice for Estimation of the Spectral Bandwidth ofUltraviolet-Visible Spectrophotometers1This guide is under the jurisdiction of ASTM Committee D19 on Water and isthe direct responsibility of Subcommittee D19.05 on Inorganic Constituents inWater.Current edition approved Jan.1,2013.Published February 2013.Originallyapproved in 1993.Last previous edition approved in 2008 as D5463 08.DOI:10.1520/D5463-13.2Test kits for determining inorganic analytes in water are available from variousUnited States and foreign manufacturers,as well as from laboratory supplycompanies.3For 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.Uni
