4.1 These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications, particularly those under the jurisdiction of the ASTM Committee A01 on Steel, Stainless Steel and Related Alloys. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.1.1 These test methods cover the chemical analysis of high-temperature, electrical, magnetic, and other similar iron, nickel, and cobalt alloys having chemical compositions within the following limits: Element Composition Range, % Aluminum 0.005 to 18.00 Beryllium 0.001 to 0.05 Boron 0.001 to 1.00 Calcium 0.002 to 0.05 Carbon 0.001 to 1.10 Chromium 0.10 to 33.00 Cobalt 0.10 to 75.00 Columbium (Niobium) 0.01 to 6.0 Copper 0.01 to 10.00 Iron 0.01 to 85.00 Magnesium 0.001 to 0.05 Manganese 0.01 to 3.0 Molybdenum 0.01 to 30.0 Nickel 0.10 to 84.0 Nitrogen 0.001 to 0.20 Phosphorus 0.002 to 0.08 Silicon 0.01 to 5.00 Sulfur 0.002 to 0.10 Tantalum 0.005 to 10.0 Titanium 0.01 to 5.00 Tungsten 0.01 to 18.00 Vanadium 0.01 to 3.25 Zirconium 0.01 to 2.50 1.2 The test methods in this standard are contained in the sections indicated below: Sections Aluminum, Total, by the 8-Quinolinol Gravimetric Method (0.20 % to 7.00 %) 100 – 107Carbon, Total, by the Combustion-Thermal Conductivity Method—Discontinued 1986 124 – 134Carbon, Total, by the Combustion Gravimetric Method (0.05 % to 1.10 %)—Discontinued 2014 79 – 89Chromium by the Atomic Absorption Spectrometry Method (0.006 % to 1.00 %) 165 – 174Chromium by the Peroxydisulfate Oxidation—Titration Method (0.10 % to 33.00 %) 175 – 183Chromium by the Peroxydisulfate-Oxidation Titrimetric Method— Discontinued 1980 116 – 123Cobalt by the Ion-Exchange-Potentiometric Titration Method (2 % to 75 %) 53 – 60Cobalt by the Nitroso-R-Salt Spectrophotometric Method (0.10 % to 5.0 %) 61 – 70Copper by Neocuproine Spectrophotometric Method (0.01 % to 10.00 %) 90 – 99Copper by the Sulfide Precipitation-Electrodeposition Gravimetric Method (0.01 % to 10.00 %) 71 – 78Iron by the Silver Reduction Titrimetric Method (1.0 % to 50.0 %) 192 –199Manganese by the Metaperiodate Spectrophotometric Method (0.05 % to 2.00 %) 9 – 18Molybdenum by the Ion Exchange—8-Hydroxyquinoline Gravi- metric Method (1.5 % to 30 %) 184 – 191Molybdenum by the Thiocyanate Spectrophotometric Method (0.01 % to 1.50 %) 153 – 164Nickel by the Dimethylglyoxime Gravimetric Method (0.1 % to 84.0 %) 135 – 142Phosphorus by the Molybdenum Blue Spectrophotometric Method (0.002 % to 0.08 %) 19 – 30Silicon by the Gravimetric Method (0.05 % to 5.00 %) 46 – 52Sulfur by the Gravimetric Method—Discontinued 1988 Former 30 – 36Sulfur by the Combustion-Iodate Titration Method (0.005 % to 0.1 %)—Discontinued 2014 37 – 45Sulfur by the Chromatographic Gravimetric Method—Discontinued 1980 108 – 115Tin by the Solvent Extraction–Atomic Absorption Spectrometry Method (0.002 % to 0.10 %) 143 – 1521.3 Methods for the determination of carbon and sulfur not included in this standard can be found in Test Methods E1019.1.4 Some of the composition ranges given in 1.1 are too broad to be covered by a single method and therefore this standard contains multiple methods for some elements. The user must select the proper method by matching the information given in the and Interference sections of each method with the composition of the alloy to be analyzed.1.5 Units—The values stated in SI units are to be regarded as standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 6 and in special “Warning” paragraphs throughout these test methods.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
