This International Standard describes a method of using phase-sensitive eddy-current instruments for nondestructive measurements of the thickness of non-magnetic metallic coatings on metallic and non-metallic basis materials, such as: a) zinc, cadmium, copper, tin or chromium on steel; b) copper or silver on composite materials. The phase-sensitive method can be applied without thickness errors to smaller surface areas and to stronger surface curvatures than the amplitude-sensitive eddy-current method described in ISO 2360[1], and is less affected by the magnetic properties of the basis material. However, the phase-sensitive method is more affected by the electrical properties of the coating materials. When measuring metallic coatings on metallic basis materials, the product of conductivity and permeability├│, ┬Á
