1.1 These test methods cover the chemical analysis of carbon steels, low-alloy steels, silicon electrical steels, ingot iron, and wrought iron having chemical compositions within the following limits: Element  Composition Range, % Aluminum 0.001  to 1.50 Antimony 0.002  to 0.03 Arsenic 0.0005 to 0.10 Bismuth 0.005  to 0.50 Boron 0.0005 to 0.02 Calcium 0.0005 to 0.01 Cerium 0.005  to 0.50 Chromium 0.005  to 3.99 Cobalt 0.01   to 0.30 Columbium (Niobium) 0.002  to 0.20 Copper 0.005  to 1.50 Lanthanum 0.001  to 0.30 Lead 0.001  to 0.50 Manganese 0.01   to 2.50 Molybdenum 0.002  to 1.50 Nickel 0.005  to 5.00 Nitrogen 0.0005 to 0.04 Oxygen 0.0001 to 0.03 Phosphorus 0.001  to 0.25 Selenium 0.001  to 0.50 Silicon 0.001  to 5.00 Sulfur 0.001  to 0.60 Tin 0.002  to 0.10 Titanium 0.002  to 0.60 Tungsten 0.005  to 0.10 Vanadium 0.005  to 0.50 Zirconium 0.005  to 0.15 1.2 The test methods in this standard are contained in the sections indicated as follows: Sections Aluminum, Total, by the 8-Quinolinol Gravimetric  Method (0.20 % to 1.5 %) 124–131 Aluminum, Total, by the 8-Quinolinol  Spectrophotometric Method  (0.003 % to 0.20 %) 76–86 Aluminum, Total or Acid-Soluble, by the Atomic  Absorption Spectrometry Method  (0.005 % to 0.20 %) 308–317 Antimony by the Brilliant Green Spectrophotometric  Method (0.0002 % to 0.030 %) 142–151 Bismuth by the Atomic Absorption Spectrometry  Method (0.02 % to 0.25 %) 298–307 Boron by the Distillation-Curcumin  Spectrophotometric Method  (0.0003 % to 0.006 %) 208–219 Calcium by the Direct-Current Plasma Atomic  Emission Spectrometry Method  (0.0005 % to 0.010 %) 289–297 Carbon, Total, by the Combustion Gravimetric Method  (0.05 % to 1.80 %)-Discontinued 1995 Cerium and Lanthanum by the Direct Current Plasma  Atomic Emission Spectrometry Method  (0.003 % to 0.50 % Cerium, 0.001 % to 0.30 %  Lanthanum) 249–257 Chromium by the Atomic Absorption Spectrometry  Method (0.006 % to 1.00 %) 220–229 Chromium by the Peroxydisulfate Oxidation-Titration  Method (0.05 % to 3.99 %) 230–238 Cobalt by the Nitroso-R Salt Spectrophotometric  Method (0.01 % to 0.30 %) 53–62 Copper by the Sulfide Precipitation-Iodometric  Titration Method (Discontinued 1989) 87–94 Copper by the Atomic Absorption Spectrometry  Method (0.004 % to 0.5 %) 279–288 Copper by the Neocuproine Spectrophotometric  Method (0.005 % to 1.50 %) 114–123 Lead by the Ion-Exchange-Atomic Absorption  Spectrometry Method  (0.001 % to 0.50 %) 132–141 Manganese by the Atomic Absorption Spectrometry  Method (0.005 % to 2.0 %) 269–278 Manganese by the Metaperiodate Spectrophotometric  Method (0.01 % to 2.5 %) 9–18 Manganese by the Peroxydisulfate-Arsenite Titrimetric  Method (0.10 % to 2.50 %) 164–171 Molybdenum by the Thiocyanate Spectrophotometric  Method (0.01 % to 1.50 %) 152–163 Nickel by the Atomic Absorption Spectrometry  Method (0.003 % to 0.5 %) 318–327 Nickel by the Dimethylglyoxime Gravimetric  Method (0.1 % to 5.00 %) 180–187 Nickel by the Ion-Exchange-Atomic-Absorption  Spectrometry Method  (0.005 % to 1.00 %) 188–197 Nitrogen by the Distillation-Spectrophotometric  Method (Discontinued 1988) 63–75 Phosphorus by the Alkalimetric Method  (0.02 % to 0.25 %) 172–179 Phosphorus by the Molybdenum Blue  Spectrophotometric Method  (0.003 % to 0.09 %) 19–30 Silicon by the Molybdenum Blue Spectrophotometric  Method (0.01 % to 0.06 %) 103–113 Silicon by the Gravimetric Titration  Method (0.05 % to 3.5 %) 46–52 Sulfur by the Gravimetric Method  (Discontinued 1988) 31–36 Sulfur by the Combustion-Iodate Titration Method  (0.005 % to 0.3 %) (Discontinued 2017) 37–45 Tin by the Sulfide Precipitation-Iodometric Titration  Method (0.01 % to 0.1 %) 95–102 Tin by the Solvent Extraction-Atomic Absorption  Spectrometry Method  (0.002 % to 0.10 %) 198–207 Titanium by the Diantipyrylmethane  Spectrophotometric Method  (0.025 % to 0.30 %) 258–268 Vanadium by the Atomic Absorption Spectrometry  Method (0.006 % to 0.15 %) 239–248 1.3 Test methods for the determination of several elements 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 test method with the composition of the alloy to be analyzed. 1.5 The values stated in SI units are to be regarded as standard. In some cases, exceptions allowed in IEEE/ASTM SI 10 are also used. 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.
