Inorganic Surface Coatings – Coating Thickness Measurement – Non-Magnetic Metallic Coatings on Metallic and Non-Metallic Substrates – Phase-Sensitive Eddy Current Method. ISO 21968:2019 details the phase-sensitive eddy current method for measuring the thickness of non-magnetic metallic coatings on metallic and non-metallic substrates. This non-destructive technique is precise for thin coatings. The standard outlines testing procedures, equipment requirements, and calibration to ensure accurate results. This method is widely used in electronics, aerospace, and other sectors where precision is critical for surface treatment functionality.
