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 to smaller surface areas and smaller surface curvatures than the current amplitude sensitive eddy current method described in ISO 2360, 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.
