The DS/ISO 2 2553-14 standard is part 14 on Paints and varnish electrodeposition coatings, focusing on the deposition performance of coatings. The standard defines the deposition behavior of electrodeposition coatings, including key performance indicators such as coating uniformity, thickness, adhesion, etc. Through standardized test methods, it is possible to evaluate the deposition effect of intermediate coatings under different conditions during the electrodeposition process, ensuring the Stability and Reliability of the coating mass. This standard applies to the quality control and research and development of Paints, varnish and Miscellaneous electrodeposition coatings, and provides a scientific basis and operation guide for Coating manufacturers and Applications.
