1.1 This test method covers the simultaneous determination of 21 alloying and residual elements in carbon and low-alloy steels by spark atomic emission vacuum spectrometry in the mass fraction ranges shown Note 1.

Element Composition Ranges (%):

Element Composition Range, %
Applicable Range,
Mass Fraction %A
Quantitative Range,
Mass Fraction %B
Aluminum0 to 0.0930.006 to 0.093
Antimony0 to 0.0270.006 to 0.027
Arsenic0 to 0.10.003 to 0.1
Boron0 to 0.0070.0004 to 0.007
Calcium0 to 0.0030.002 to 0.003
Carbon0 to 1.10.02 to 1.1
Chromium0 to 8.20.007 to 8.14
Cobalt0 to 0.200.006 to 0.20
Copper0 to 0.50.006 to 0.5
LeadC0 to 0.20.002 to 0.2
Manganese0 to 2.00.03 to 2.0
Molybdenum0 to 1.30.007 to 1.3
Nickel0 to 5.00.006 to 5.0
Niobium0 to 0.120.003 to 0.12
Nitrogen0 to 0.0150.01 to 0.055
Phosphorous0 to 0.0850.006 to 0.085
Silicon0 to 1.540.02 to 1.54
Sulfur0 to 0.0550.001 to 0.055
Tin0 to 0.0610.005 to 0.061
Titanium0 to 0.20.001 to 0.2
Vanadium0 to 0.30.003 to 0.3
Zirconium0 to 0.050.01 to 0.05

Note 1: The mass fraction ranges of the elements listed have been established through cooperative testing2 of reference materials.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 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.

5.1 This test method for the spectrometric analysis of metals and alloys is primarily intended to test such materials for compliance with compositional specifications.

It is assumed that all who use this test method will be analysts capable of performing common laboratory procedures skillfully and safely.

It is expected that work will be performed in a properly equipped laboratory.
