Significance and Use | ||||||||||||||||||||||||||
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. |

1. Scope | ||||||||||||||||||||||||||
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). 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. |
