European foreword
This document (EN 13226:2024) has been prepared by Technical Committee CEN/TC 175 “Round and
sawn timber”, the secretariat of which is held by AFNOR.
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 June 2025, and conflicting national standards shall be
withdrawn at the latest by June 2025.
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 13226:2009.
Compared to EN 13226:2009, the following changes have been made:
— normative references updated;
— replacement of the term “strip” by “element” in Clause 3 “Terms and definitions”;
— Annex A (informative) “Botanical and trade names of the most commonly used species for wood
flooring (hardwood and softwood species)” of wood is deleted and replaced by reference to the
nomenclature standard EN 13556 “Round and sawn timber - Nomenclature of timbers used in
Europe”;
— addition of a general rules appearance (5.2.1.);
— addition of keys for Figure 1;
— editorials modifications.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
This document is one of a series of standards concerning wood flooring and wood panelling and cladding.
This document specifies the characteristics of solid parquet elements. It is based upon current
dimensional standards within the industry and other characteristics together with functions which have
been verified by test.
A large amount of knowledge exists about solid parquet elements and values for product characteristics
are attested by long use and experience. It is therefore not necessary to have test results. For new
products, technical data will have to be verified by testing.
The appearance of the parquet is mainly influenced by species, classification and the pattern.
1 Scope
This document specifies the characteristics of solid parquet elements with grooves and/or tongues for
internal use as flooring. This document is applicable to elements of parquet panels.
This document covers elements with or without surface treatment.

5 Specific product requirements
5.1 Wood species
A list of the most commonly used species for parquet elements are described in EN 13556. For
nomenclature of wood species used in Europe, see EN 13556.
5.2 Appearance
5.2.1 General rules
Tables 1 to 9 define the classification relating to appearance rules for the face and for the non-visible
parts (back and edges) of an element of the most commonly used species for solid wood flooring as
defined in this standard.
Features shall be measured according to EN 1309-3 (knots assessed according to the general method of
5.1 in EN 1309-3:2018) Biodeterioration is measured according to EN 1309-3.
A classification with three appearance classes is specified, designated ○, Δ and ◻.
A classification named “Free class” is based on the principles laid out in Annex A.
1)
The face shall include all the visible surface of the element. It shall therefore extend to the chamfering if
any.
The face shall be free from shake and the wood shall be sound.

1)
The chamfering is visible when elements are assembled.
Any continuous glue joint which allows renovation without significantly changing the appearance or the
functional characteristics is acceptable.
In order to allow unavoidable differences in the sorting classes, 3 % of the elements in adjacent areas
may come from other sorting classes. All additional elements from other sorting classes are permitted as
long as the overall appearance of the floor is not affected.
NOTE To obtain a homogenous appearance of the installed floor the elements are supposed to be sorted before
installation.
5.2.2 Rules for the most commonly used species
