This International Standard specifies a glow discharge optical emission spectrometric method for the determination of the thickness, mass per unit area and chemical composition of metallic surface coatings consisting of zinc- and/or aluminium-based materials. The alloying elements considered are nickel, iron, silicon, lead and antimony.
This method is applicable to
zinc contents between 0,01 mass % and 100 mass %;
aluminium contents between 0,01 mass % and 100 mass %;
nickel contents between 0,01 mass % and 20 mass %;
iron contents between 0,01 mass % and 20 mass %;
silicon contents between 0,01 mass % and 10 mass %;
lead contents between 0,005 mass % and 2 mass %;
antimony contents between 0,005 mass % and 2 mass %.
