1.1 This test method covers the simultaneous determination of 20 alloying and residual elements in carbon and low-alloy steels by spark atomic emission vacuum spectrometry in the mass fraction ranges shown (Note 1). Composition Range, % Element Applicable Range, Mass Fraction % A Quantitative Range, Mass Fraction % B Aluminum 0 to 0.075 0.02 to 0.075 Arsenic 0 to 0.1 0.05 to 0.1 Boron 0 to 0.007 0.002 to 0.007 Calcium 0 to 0.003 0.001 to 0.003 Carbon 0 to 1.1 0.08 to 1.1 Chromium 0 to 2.25 0.02 to 2.25 Cobalt 0 to 0.18 0.008 to 0.18 Copper 0 to 0.5 0.04 to 0.5 Manganese 0 to 2.0 0.10 to 2.0 Molybdenum 0 to 0.6 0.03 to 0.6 Nickel 0 to 5.0 0.02 to 5.0 Niobium 0 to 0.085 0.02 to 0.085 Nitrogen 0 to 0.015 0.004 to 0.015 Phosphorous 0 to 0.085 0.02 to 0.085 Silicon 0 to 1.15 0.07 to 1.15 Sulfur 0 to 0.055 0.01 to 0.055 Tin 0 to 0.045 0.01 to 0.045 Titanium 0 to 0.2 0.004 to 0.2 Vanadium 0 to 0.3 0.004 to 0.3 Zirconium 0 to 0.05 0.02 to 0.05 A Applicable range in accordance with Guide E1763 for results reported in accordance with Practice E1950. B Quantitative range in accordance with Practice E1601. Note 1 - The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials. Included, in addition to the original data of Test Method E415-71, are data from cooperative testing of a broader range of reference materials to expand the element mass fraction ranges. 1.2 This test method covers analysis of specimens having a diameter adequate to overlap and seal the bore of the spark stand opening. The specimen thickness can vary significantly according to the design of the spectrometer stand, but a thickness between 10 mm and 38 mm has been found to be most practical. 1.3 This test method covers the routine control analysis in iron and steelmaking operations and the analysis of processed material. It is designed for chill-cast, rolled, and forged specimens. Better performance is expected when reference materials and specimens are of similar metallurgical condition and composition. However, it is not required for all applications of this standard. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
