Designation:E147309Standard Test Methods forChemical Analysis of Nickel,Cobalt,and High-TemperatureAlloys1This standard is issued under the fixed designation E1473;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.Scope1.1 These test methods describe the chemical analysis ofnickel,cobalt,and high-temperature alloys having chemicalcompositions within the following limits:ElementConcentration Range,%Aluminum0.005 to7.00Beryllium0.001 to0.05Boron0.001 to1.00Calcium0.002 to0.05Carbon0.001 to1.10Chromium0.10to 33.00Cobalt0.10to 75.00Copper0.01to 35.00Iron0.01to 50.00Lead0.001 to0.01Magnesium0.001 to0.05Manganese0.01to3.0Molybdenum0.01to 30.0Niobium(Columbium)0.01to6.0Nickel0.10to 98.0Nitrogen0.001 to0.20Phosphorus0.002 to0.08Sulfur0.002 to0.10Silicon0.01to5.00Tantalum0.005 to1.00Tin0.002 to0.10Titanium0.01to5.00Tungsten0.01to 18.00Vanadium0.01to3.25Zinc0.001 to0.01Zirconium0.01to2.501.2 The test methods in this standard are contained in thesections indicated as follows:SectionsAluminum,Total by the 8-Quinolinol Gravimetric Method(0.20%to 7.00%)262 to 69Chromium by the Atomic Absorption Method(0.018%to 1.00%)2100 to 109Chromium by the Peroxydisulfate OxidationTitration Method(0.10%to 33.00%)2110 to 118Cobalt by the Ion-Exchange-Potentiometric Titration Method(2%to 75%)234 to 41Cobalt by the Nitroso-R-Salt Photometric Method(0.10%to 5.0%)242 to 51Copper by Neocuproine Photometric Method(0.010%to10.00%)252 to 61Iron by the Silver Reduction Titrimetric Method(1.0%to 50.0%)2127 to 134Manganese by the Metaperiodate Photometric Method(0.05%to2.00%)28 to 17Molybdenum by the Ion Exchange8-HydroxyquinolineGravimetric Method(1.5%to 30%)2119 to 126Molybdenum by the Photometric Method(0.01%to 1.50%)288 to 99Nickel by the Dimethylglyoxime Gravimetric Method(0.1%to 84.0%)270 to 77Niobium by the Ion ExchangeCupferron Gravimetric Method(0.5%to 6.0%)135 to 142Silicon by the Gravimetric Method(0.05%to 5.00%)227 to 33Sulfur by the Combustion-Iodate Titration Method(0.006%to 0.1%)218 to 26Tantalum by the Ion ExchangePyrogallol SpectrophotometricMethod(0.03%to 1.0%)143 to 151Tin by the Solvent Extraction-Atomic Absorption Method(0.002%to 0.10%)278 to 871.3 Methods for the determination of several elements notincluded in these test methods can be found in Test MethodsE30,E76,and E1019.1.4 Some of the concentration ranges given in 1.1 are toobroad to be covered by a single method,and therefore,thesetest methods contain multiple methods for some elements.Theuser must select the proper test method by matching theinformation given in the scope and interference sections ofeach test method with the composition of the alloy to beanalyzed.1.5 The values stated in SI units are to be regarded asstandard.In some cases,exceptions allowed in Practice E380are also used.1.6 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.Specific hazard1These test methods are under the jurisdiction of ASTM Committee E01 onAnalytical Chemistry for Metals,Ores,and Related Materials and are the directresponsibility of Subcommittee E01.08 on Ni and Co and High TemperatureAlloys.Current edition approved June 1,2009.Published July 2009.Originally approvedin 1992.Last previous edition approved in 2003 as E1473 03.DOI:10.1520/E1473-09.2These test methods were extracted from Test Methods E354 and the referencesto Test Methods E350,E351,E352,and E353 contained therein.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 statements are given in Section 7 and in 13.4,29.1,66.3,123.5,124.14,139.4,139.5,147.5,and 147.6.2.Referenced Documents2.1 ASTM Standards:3D1193 Specification for Reagent WaterE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE30 Test Methods for ChemicalAnalysis of Steel,Cast Iron,Open-Hearth Iron,and Wrought Iron(Withdrawn 1995)4E50 Practices for Apparatus,Reagents,and Safety Consid-erations for Chemical Analysis of Metals,Ores,andRelated MaterialsE60 Practice for Analysis of Metals,Ores,and RelatedMaterials by SpectrophotometryE76 Test Methods for Chemical Analysis of Nickel-CopperAlloys(Withdrawn 2003)4E135 Terminology Relating to Analytical Chemistry forMetals,Ores,and Related MaterialsE173 Practice for Conducting Interlaboratory Studies ofMethods for Chemical Analysis of Metals(Withdrawn1998)4E350 Test Methods for Chemical Analysis of Carbon Steel,Low-Alloy Steel,Silicon Electrical Steel,Ingot Iron,andWrought IronE351 Test Methods for ChemicalAnalysis of Cast IronAllTypesE352 Test Meth
