European foreword
This document (EN 13523-20:2020) has been prepared by Technical Committee CEN/TC 139 “Paints and
varnishes”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by December 2020, and conflicting national standards shall be
withdrawn at the latest by December 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13523-20:2011.
The main changes are:
a) testing of non-adhesion in domestic appliance products has been added (9.2.3);
b) the text has been editorially revised and the normative references have been updated.
The EN 13523 series, Coil coated metals — Test methods, consists of the following parts:
— Part 0: General introduction
— Part 1: Film thickness
— Part 2: Gloss
— Part 3: Colour difference — Instrumental comparison
— Part 4: Pencil hardness
— Part 5: Resistance to rapid deformation (impact test)
— Part 6: Adhesion after indentation (cupping test)
— Part 7: Resistance to cracking on bending (T-bend test)
— Part 8: Resistance to salt spray (fog)
— Part 9: Resistance to water immersion
— Part 10: Resistanc
