European foreword
This document (EN 16511:2023) has been prepared by Technical Committee CEN/TC 134 “Resilient,
textile and laminate floor coverings”, the secretariat of which is held by NBN.
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 November 2023, and conflicting national standards shall
be withdrawn at the latest by November 2023.
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 16511:2014+A1:2019.
The main changes compared to the previous edition are listed below:
a) title changed;
b) terms and definitions added in Clause 3;
c) EN 17539 included as test method for general requirements in 5.1;
d) light fastness and dimensional stability added as general requirements in 5.1;
e) classification requirements divided in floorings with wear layers (Table 2) and floorings with non-
film-forming oil or wax finishes (Table 3);
f) additional technical characteristics for moisture resistance added as Table 4;
g) Annex B presenting a test method for the classification of the flexibility added.
Any feedback and questions on this document should be directed to the users’ national standards body.

1 Scope
This document specifies the characteristics of multilayer mechanical locked floor covering with a wear-
resistant and decorative surface layer supplied in panels (either tile or plank form). The floor panels are
considered suitable for domestic and commercial levels of use and designed for floating installation.
This document does not apply to resilient floor panels for loose-laying according to EN ISO 20326, to
multilayer wood floorings according to EN 13489, to wood veneer floor coverings according to EN 14354,
to laminate floor covering according to EN 13329, EN 14978 and EN 15468 nor to products specified in
EN ISO 10581, EN ISO 10582, EN ISO 24011, EN 12104 and ISO 14486.
This document is applicable to areas which are subject to frequent wetting, e.g. bathrooms, laundry rooms
or saunas, only if specified by the producer.
This document also includes requirements for marking and packaging.
In Annex A (informative), optional properties are given. In Annex B (informative), a test method for the
classification of the flexibility is given.
