This standard describes a method for the photometric determination of the arsenic content up to 0.05% (m/m) and is applicable to the chemical examination of iron and non-alloy steel. The detection limit is approximately 0.000 3% (m/m) arsenic. The determination is not dis urbed by the elements normally found in iron and non-alloy steel.
