This European Standard was approved by CEN on 3 May 2020.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

European foreword
This document (EN 13523-6:2020) 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withdrawn at the latest by December 2020.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 13523-6:2002.
The main changes are:
a) the period of ageing has been changed from 1 h to agreement prior to the test (8.4);
b) the time of ageing has been added to the test report;
c) 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: Resistance to fluorescent UV radiation and water condensation
— Part 11: Resistance to solvents (rubbing test)
— Part 12: Resistance to scratching
— Part 13: Resistance to accelerated ageing by the use of heat
— Part 14: Chalking (Helmen method)
— Part 15: Metamerism
— Part 16: Resistance to abrasion
— Part 17: Adhesion of strippable films
— Part 18: Resistance to staining
— Part 19: Panel design and method of atmospheric exposure testing
— Part 20: Foam adhesion
— Part 21: Evaluation of outdoor exposed panels
