Overview
The DIN 55655 series of standards specifies test methods for electro-deposition coatings for automotive industries and other general industrial applications, such as chiller units, consumer products, radiators, aerospace and agriculture. This document specifies a method for identifying entry marks, which can occur during electrodeposition coating. Entry marks can often occur in the form of streaks when the workpiece, either set as cathode or anode, is immersed in the electro-deposition tank under applied electric potential (relation of voltage and current). These marks occur parallel to the bath surface on the objects to be coated. This responsible working committee is Working Group NA 002-00-07-09 AK "Automobilbeschichtungen" ("Automotive coatings") of Working Committee NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") at DIN Standards Committee Coatings and Coating Materials (NAB).
