This document specifies an inductively coupled plasma optical emission spectrometric method (ICP-OES) for the analysis of aluminium and aluminium alloys. This method is applicable to the determination of silicon, iron, copper, manganese, magnesium, chromium, nickel, zinc, titanium, gallium, vanadium, beryllium, bismuth, calcium, cadmium, cobalt, lithium, sodium, lead, antimony, tin, strontium and zirconium in aluminium and aluminium alloys. The content of the elements to be determined should be at least 10 times higher than the corresponding detection limits.
