5.1 Paints electroplated by the action of an electric field (oven drying)
The industrial development of electrophoretic paints began in the 1980s for three main reasons:
increase the corrosion resistance of metallic materials by making it easier to paint hollow bodies;
increased productivity ;
improved working conditions thanks to the elimination of solvent vapours during application. The paint deposit is obtained by immersing the parts in a water-soluble binder as soon as an electric field is applied.
Electroplating is achieved either by cataphoresis or anaphoresis, depending on the chemical nature of the binder. These deposition processes...

Different types of standards exist:
national standards specific to each country (AFNOR in France, ASTM in the United States, DIN in Germany, BSI in Great Britain);
international standards of worldwide scope, set up by ISO but whose use is not mandatory in individual countries;

Paints for food contact
All items likely to come into contact with foodstuffs must meet inertness requirements so as not to impart any taste to the food or allow any of their constituents to migrate.
The regulations take up these requirements by setting out the list of substances authorized...
