Metallic coatings — Measurement of coating thickness — Coulometric method by anodic dissolution

This second edition cancels and replaces the first edition (i. e. ISO 2177:1972).Typical combinations of coatings and substrates that can be tested by this method are given in table 1. The method is also applicable to multi-layer systems. In some cases, the presence and thickness of diffusion layers, and the thickness of coatings on cylindrical specimens and wires, can also be measured.
