ISO 2 2553-8 is an international standard on the determination of charge density of electrodeposited coatings. The standard specifies methods for measuring charge density on electrodeposited coatings to ensure coating mass and adaptability. The standard specifies experimental equipment, experimental procedures and data processing methods. Specifically, the standard requires coatings to be tested under specific conditions using a charge meter or capacitance meter, and then the charge density of the coating is calculated. The standard also specifies accuracy and Reliability requirements for the determination, as well as how the test results are reported. The standard applies to a wide range of electrodeposited coatings, including automotive parts, metalwork and electronics, among others.
