ISO (הארגון הבינלאומי לתקינה) היא פדרציה עולמית של גופי תקינה לאומיים (גופים חברי ISO). פיתוח תקנים בינלאומיים מתבצע בדרך כלל באמצעות ועדות טכניות של ISO. כל קבוצת חברים המעוניינת בנושא שלגביו הוקמה ועדה טכנית זכאית להיות מיוצג בוועדה. ארגונים בינלאומיים, ממשלות וארגונים לא-ממשלתיים בקשר עם ISO מעורבים גם הם בעבודה זו. ISO עובד בשיתוף פעולה הדוק עם הנציבות האלקטרוטכנית הבינלאומית (חברת החשמל) בכל הקשור לתקינה חשמלית.

In the electrodeposition coating process, the non-volatile substances in the water-dilutive electrodeposition coating are deposited on the workpiece by the electrophoretic process. During this process, 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 (see Figure 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.

לָכֵן, 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 (חוֹם, water-based media, carbon sources, וכו ').

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.
