The ISO 2360-2017 standard specifies a method for the measurement of nonconductive Coating thickness on nonmagnetic conductive substrates using amplitude-sensitive eddy current method. The method is suitable for a variety of coating materials such as paints, Eletroplating coatings, enamel coatings and plastic coatings, among others. The standard details the adjustment and calibrating process of the measurement system, ensuring accurate and reliable measurement results. ISO 2360 is particularly suitable for thickness measurement of most oxide coatings, but not all conversion coatings or very thin coatings. The standard also mentions the use of amplitude-sensitive eddy current for the measurement of nonmagnetic metallic coatings on nonconductive substrates, while emphasizing special considerations for extremely thin coatings and magnetic base metallic coatings. The implementation of ISO 2360-2017 helps to ensure the accuracy and conformity of Coating thickness measurements, facilitating quality control and product performance evaluation in industrial applications.
