ايزو (المنظمة الدولية للمقاييس) هو اتحاد عالمي لهيئات المعايير الوطنية (الهيئات الأعضاء في منظمة الأيزو). عادة ما يتم تطوير المعايير الدولية من خلال اللجان الفنية ISO. Each member group interested in a subject for which a technical committee has been established has the right to be represented on the Committee. منظمات دولية, governments and non-governmental organizations in contact with ISO are also involved in this work. تعمل ISO بشكل وثيق مع اللجنة الكهروتقنية الدولية (اللجنة الانتخابية المستقلة) في جميع المسائل المتعلقة بالتوحيد الكهربائي.

In the electrodeposition coating process, the non-volatile substances in the water-dilutive electrodeposition coating are deposited on the workpiece by the electrophoretic process. خلال هذه العملية, the internal and external areas of the workpiece, including all cavities, are touched. Cathode deposition or anode deposition is distinguished according to whether the workpiece is used as cathode or anode. The cathodic electrodeposition coating process is commonly used (أنظر للشكل 1).

Key

Through the combination of adhesives, pigments and deposition processes, hardening creates a very corrosion-resistant coating on the workpiece, which contributes significantly to corrosion protection in both internal and external areas.

The electrical properties of the material are also important for the electrical energy consumption (bulk charge density) of the process.

Since the electrophoretic paint is jointly responsible for the overall appearance of the coating system, it is often emphasized that the coating works well and has no visible defects.

لذلك, for extensive corrosion protection and sealing of the workpiece, additional joint sealing materials, adhesives or foams are recommended.

Inside the electrophoresis tank, bacterial contamination may be present due to the material being dragged in and the physical conditions (حرارة, water-based media, carbon sources, إلخ.).

This document specifies the terms and definitions of electrodeposited coatings. The subsequent part of the ISO 22553 series specifies methods of characterization and testing of electrodeposited coatings. An overview of the test methods is given in Annex A.
