    Prüfmethoden

    Im Laufe der Jahre hat die ECCA eine Serie an Prüfmethoden entwickelt, ein hilfreiches Werkzeug für alle, die bandbeschichtetes Metall prüfen wollen. 1995 wurde im CEN TC139 mit ECCA-Unterstützung eine Arbeitsgruppe eingesetzt. Deren Arbeit führte zur Umwandlung der ECCA-Prüfmethoden in die EN 13523, eine europäische Norm mit über 25 Teilen.

    Hier eine Liste aller bislang veröffentlichten bzw. in Vorbereitung befindlichen
