The ISO 2 2553-14: 2021 standard specifies a method for determining the deposition behavior of electrodeposited coatings under various substrates and pretreatment conditions. This method is suitable for electrodeposited coatings in the automotive industry and in the general industrial sector of Miscellaneous, such as chillers, consumer products, radiators, aerospace equipment and agricultural machinery. The standard ensures the uniformity and adhesion of coatings in practical applications through detailed test procedures and requirements, thereby improving the overall performance and service life of coatings.
