European Foreword
This document (prEN 13226:2023) has been prepared by Technical Committee CEN/TC 175 “Round and
sawn timber”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document supersedes EN 13226:2009.
The main changes compared to the previous edition are listed below:
— New limit deviations for nominal width of the element (5.4.3.1);
— New value for cup (5.4.3.3);
— New value for spring (5.4.3.5);
— Modifications regarding the marking (Clause 6).

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 be verified by testing.
The appearance of the parquet is mainly influenced by species, classification and the pattern.

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 document.
Features shall be measured according to EN 1309-3 (knots assessed according to the general method of
5.1 in EN 1309-3) 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.
Any continuous glue joint which allows renovation without significantly changing the appearance or the
functional characteristics is acceptable.
1
The chamfering is visible when elements are assembled.

In order to allow unavoidable differences in the sorting classes, 3 % of the elements in one adjascent
areas may come from other sorting classes. All additional elements from other sorting classes are
permitted as long as the overall image of the floor is not affected.
NOTE To obtain a homogenous impression of the installed floor the elements are supposed to be sorted before
installation.
