European foreword
This document (prEN 13523-25:2020) has been prepared by Technical Committee CEN/TC 139 “Paints
and varnishes”, the secretariat of which is held by DIN.This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13523-25:2014.
The main changes are:
a) ISO 3696 has been added to 5.3 as reference for the deionized water;
b) a remark concerning the assessment of Zn/Al/Mg-coated steel substrates has been added to
Clause 9;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
— Part 4: Pencil hardness
— Part 5: Resistance to rapid deformation (impact test)
