GB/T 4955-2005 specifies anode dissolving Coulometry for film thickness measurement of metal coatings. The standard specifies the measurement principle, scope of application, equipment and operation process, calculates the film thickness of the cover layer through the electricity consumed in the anode dissolving process, and standardizes the key links such as sample preparation and electrolysis conditions. It provides a unified technical method for the accurate measurement of film thickness of metal coatings, and ensures the accuracy and reliability of product mass detection and production process control.
