1.1 This practice covers evaluation of an optical emission vacuum spectrometer to analyze carbon and low-alloy steels. It covers instruments used for the analysis of solid samples taken from molten metal for production control or from products to confirm the composition. Both pre-installation and post-installation precision and accuracy are included in the evaluation.

1.2 While Tables 1-3 are specific for plain carbon and low-alloy steel, they could be supplemented by similar tables for other materials.

1.3 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.
