This European Standard was approved by CEN on 1 January 2024.

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.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

European foreword
This document (EN 13523-8:2024) 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 October 2024, and conflicting national standards shall
be withdrawn at the latest by October 2024.
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 13523-8:2017.
a) the distance between the two scribes has been changed from 10 mm to 20 mm, to be in line with
other standards on salt spray fog tests;
b) the width of the scribe has been changed from at least “0,2 mm” to “0,2 mm to 1,0 mm”;
c) the text has been editorially revised and the normative references have been updated.

1 Scope
This document specifies the procedures for determining the resistance to salt spray (fog) of an organic
coating on a metallic substrate (coil coating).
For steel, neutral salt spray (fog) is usually used, and for aluminium, acetic acid salt spray (fog).
