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 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 1.50Antimony 0.002  to 0.03Arsenic 0.0005 to 0.10Bismuth 0.005  to 0.50Boron 0.0005 to 0.02Calcium 0.0005 to 0.01Cerium 0.005  to 0.50Chromium 0.005  to 3.99Cobalt 0.01   to 0.30Columbium (Niobium) 0.002  to 0.20Copper 0.005  to 1.50Lanthanum 0.001  to 0.30Lead 0.001  to 0.50Manganese 0.01   to 2.50Molybdenum 0.002  to 1.50Nickel 0.005  to 5.00Nitrogen 0.0005 to 0.04Oxygen 0.0001 to 0.03Phosphorus 0.001  to 0.25Selenium 0.001  to 0.50Silicon 0.001  to 5.00Sulfur 0.001  to 0.60Tin 0.002  to 0.10Titanium 0.002  to 0.60Tungsten 0.005  to 0.10Vanadium 0.005  to 0.50Zirconium 0.005  to 0.151.2 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 %) 124–131Aluminum, Total, by the 8-Quinolinol Spectrophotometric Method (0.003 % to 0.20 %) 76–86Aluminum, Total or Acid-Soluble, by the Atomic Absorption Spectrometry Method (0.005 % to 0.20 %) 308–317Antimony by the Brilliant Green Spectrophotometric Method (0.0002 % to 0.030 %) 142–151Bismuth by the Atomic Absorption Spectrometry Method (0.02 % to 0.25 %) 298–307Boron by the Distillation-Curcumin Spectrophotometric Method (0.0003 % to 0.006 %) 208–219Calcium by the Direct-Current Plasma Atomic Emission Spectrometry Method (0.0005 % to 0.010 %) 289–297Carbon, 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) 249–257Chromium by the Atomic Absorption Spectrometry Method (0.006 % to 1.00 %) 220–229Chromium by the Peroxydisulfate Oxidation-Titration Method (0.05 % to 3.99 %) 230–238Cobalt by the Nitroso-R Salt Spectrophotometric Method (0.01 % to 0.30 %) 53–62Copper by the Sulfide Precipitation-Iodometric Titration Method (Discontinued 1989) 87–94Copper by the Atomic Absorption Spectrometry Method (0.004 % to 0.5 %) 279–288Copper by the Neocuproine Spectrophotometric Method (0.005 % to 1.50 %) 114–123Lead by the Ion-Exchange—Atomic Absorption Spectrometry Method (0.001 % to 0.50 %) 132–141Manganese by the Atomic Absorption Spectrometry Method (0.005 % to 2.0 %) 269–278Manganese by the Metaperiodate Spectrophotometric Method (0.01 % to 2.5 %) 9–18Manganese by the Peroxydisulfate-Arsenite Titrimetric Method (0.10 % to 2.50 %) 164–171Molybdenum by the Thiocyanate Spectrophotometric Method (0.01 % to 1.50 %) 152–163Nickel by the Atomic Absorption Spectrometry Method (0.003 % to 0.5 %) 318–327Nickel by the Dimethylglyoxime Gravimetric Method (0.1 % to 5.00 %) 180–187Nickel by the Ion-Exchange-Atomic-Absorption Spectrometry Method (0.005 % to 1.00 %) 188–197Nitrogen by the Distillation-Spectrophotometric Method (Discontinued 1988) 63–75Phosphorus by the Alkalimetric Method (0.02 % to 0.25 %) 172–179Phosphorus by the Molybdenum Blue Spectrophotometric Method (0.003 % to 0.09 %) 19–30Silicon by the Molybdenum Blue Spectrophotometric Method (0.01 % to 0.06 %) 103–113Silicon by the Gravimetric Titration Method (0.05 % to 3.5 %) 46–52Sulfur by the Gravimetric Method (Discontinued 1988) 31–36Sulfur by the Combustion-Iodate Titration Method (0.005 % to 0.3 %) (Discontinued 2017) 37–45Tin by the Sulfide Precipitation-Iodometric Titration Method (0.01 % to 0.1 %) 95–102Tin by the Solvent Extraction-Atomic Absorption Spectrometry Method (0.002 % to 0.10 %) 198–207Titanium by the Diantipyrylmethane Spectrophotometric Method (0.025 % to 0.30 %) 258–268Vanadium by the Atomic Absorption Spectrometry Method (0.006 % to 0.15 %) 239–2481.3 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 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.

3.1 The oxidation of silicon carbide refractories at elevated temperatures is an important consideration in the application of these refractories. The product of oxidation is amorphous silica or cristobalite, depending upon the temperature at which oxidation takes place. This oxide formation is associated with expansion and degradation of strength. The quantity of water vapor in the atmosphere greatly affects the rate of oxidation.3.2 The test, which creates and measures the expansion, is suitable for guidance in product development and relative comparison in application work where oxidation potential is of concern. The variability of the test is such that it is not recommended for use as a referee test.1.1 This test method covers the evaluation of the oxidation resistance of silicon carbide refractories at elevated temperatures in an atmosphere of steam. The steam is used to accelerate the test. Oxidation resistance is the ability of the silicon carbide (SiC) in the refractory to resist conversion to silicon dioxide (SiO2) and its attendant crystalline growth.1.2 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.1.3 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.
