The ISO 2177 "measurement of metallic coatings. Coating thickness. Anode dissolve Coulometry" standard specifies the technical requirements for the measurement of metallic coating thickness by anode dissolve Coulometry. This method is suitable for the measurement of metallic coatings, especially where there is a clear boundary between the coating and the substrate. The anode dissolve method dissolves metallic coatings by electrochemistry and calculates the thickness of the coating by measuring the charge quantity required to dissolve. The standard describes in detail the experimental conditions, operating procedures, equipment requirements and error control to ensure the accuracy and repeatability of the measurement results. This method is widely used in industrial inspection, especially in applications requiring high-precision and non-Destructiveness measurement, and can provide reliable data support for coating mass.
