European foreword
This document (EN 13523-25:2022) 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 August 2022, and conflicting national standards shall be
withdrawn at the latest by August 2022.
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 13523-25:2014.
The main changes are:
a) EN ISO 3696 has been added to 6.1 as reference for the deionised water;
b) a remark concerning the assessment of organic coated steel substrates having multiple metallic
phases in zinc based coating has been added to Clause 10;
c) the list of the existing parts of EN 13523 has been updated;
d) 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 and metamerism — Instrumental comparison
