BSI BS ISO 2 2553-14 "Paints and varnish - Electrodeposition coatings - Part 14: Deposition performance" standard specifies the method and technical requirements for evaluating the deposition behavior of electrodeposition coatings. The standard applies to the coating process of electrophoretic coatings on different substrate surfaces, focusing on the uniformity, adhesion and coverage performance of the coating. The standard describes in detail the test equipment, operating conditions and technical details of the evaluation of results, providing a scientific basis for ensuring the mass and conformity of electrodeposition coatings.
