This 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 %.
NOTE : The International Standard corresponding to this Standard is as follows.
ISO 16962:2005 Surface chemical analysis-Analysis of zinc- and/or aluminium-bascd metallic coatings by glow-discharge optical-emission spectrometry (IDT)
In addition, symbols which denote the degree of correspondence in the contents between the relevant international Standard and JIS are IDT/identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.
