Application Summary AI generated
This standard specifies an inductively coupled plasma-optical emission spectrometric (ICP-OES) method for simultaneously determining eleven elements—lead, cadmium, iron, copper, tin, aluminum, arsenic, antimony, magnesium, lanthanum, and cerium—in zinc and zinc alloys. It is applied in the metallurgical industry for quality control and chemical analysis of raw zinc materials and finished zinc alloy products, particularly where accurate multi-element quantification is required for compliance with material specifications.
