Surface chemical analysis — Analysis of zinc- and/or aluminium-based metallic coatings by glow-discharge optical-emission spectrometry

ISO 16962:2005 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 %.
