Scope of standard 1.1 These test methods cover the chemical analysis of stainless, heat-resisting, maraging, and other similar chromium-nickel-iron alloys having chemical compositions within the following limits: Element Composition Range, % Aluminum 0.002 to 5.50 Boron 0.001 to 0.20 Carbon 0.01 to 1.50 Chromium 0.01 to 35.00 Cobalt 0.01 to 15.00 Niobium 0.01 to 4.00 Copper 0.01 to 5.00 Lead 0.001 to 0.50 Manganese 0.01 to 20.00 Molybdenum 0.01 to 7.00 Nickel 0.01 to 48.00 Nitrogen 0.001 to 0.50 Phosphorus 0.002 to 0.35 Selenium 0.01 to 0.50 Silicon 0.01 to 4.00 Sulfur 0.002 to 0.50 Tantalum 0.01 to 0.80 Tin 0.001 to 0.05 Titanium 0.01 to 4.50 Tungsten 0.01 to 4.50 Vanadium 0.005 to 1.00 Zirconium 0.001 to 0.20 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 %) 119-126 Aluminum, Total, by the 8-Quinolinol Spectrophotometric Method (0.003 % to 0.20 %) 71-81 Carbon, Total, by the Combustion-Thermal Conductivity Method-Discontinued 1986 153-163 Carbon, Total, by the Combustion Gravimetric Method (0.05 % to 1.50 %)-Discontinued 2013 98-108 Chromium by the Atomic Absorption Spectrometry Method (0.006 % to 1.00 %) 202-211 Chromium by the Peroxydisulfate Oxidation-Titration Method (0.10 % to 35.00 %) 212-220 Chromium by the Peroxydisulfate-Oxidation Titrimetric Method-Discontinued 1980 145-152 Cobalt by the Ion-Exchange-Potentiometric Titration Method (2 % to 15 %) 53-60 Cobalt by the Nitroso-R-Salt Spectrophotometric Method (0.01 % to 5.0 %) 61-70 Copper by the Neocuproine Spectrophotometric Method (0.01 % to 5.00) %) 109-118 Copper by the Sulfide Precipitation-Electrodeposition Gravimetric Method (0.01 % to 5.00 %) 82-89 Lead by the Ion-Exchange-Atomic Absorption Spectrometry Method (0.001 % to 0.50 %) 127-136 Manganese by the Periodate Spectrophotometric Method (0.01 % to 5.00 %) 9-18 Molybdenum by the Ion Exchange-8-Hydroxyquinoline Gravimetric Method 242-249 Molybdenum by the Thiocyanate Spectrophotometric Method (0.01 % to 1.50 %) 190-201 Nickel by the Dimethylglyoxime Gravimetric Method (0.1 % to 48.0 %) 172-179 Phosphorus by the Alkalimetric Method (0.02 % to 0.35 %) 164-171 Phosphorus by the Molybdenum Blue Spectrophotometric Method (0.002 % to 0.35 %) 19-30 Silicon by the Gravimetric Method (0.05 % to 4.00 %) 46-52 Sulfur by the Gravimetric Method-Discontinued 1988 30-36 Sulfur by the Combustion-Iodate Titration Method (0.005 % to 0.5 %)-Discontinued 2014 37-45 Sulfur by the Chromatographic Gravimetric Method-Discontinued 1980 137-144 Tin by the Solvent Extraction-Atomic Absorption Spectrometry Method (0.002 % to 0.10 %) 180-189 Tin by the Sulfide Precipitation-Iodometric Titration Method (0.01 % to 0.05 %) 90-97 Titanium by the Diantipyrylmethane Spectrophotometric Method (0.01 % to 0.35 %) 231-241 Vanadium by the Atomic Absorption Spectrometry Method (0.006 % to 0.15 %) 221-230 1.3 Test 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 test method and therefore this standard contains multiple test methods for some elements. The user must select the proper test method by matching the information given in the Scope and Interference sections of each method with the composition of the alloy to be analyzed. 1.5 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.
