Foreword
This document (EN 13226:2002) 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 2003, and conflicting national standards shall be
withdrawn at the latest by June 2003.
In this European Standard the annex A is informative and the annex B is normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands,
Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard is one of a series of standards concerning wood flooring and wood panelling
and cladding.
This standard 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 European Standard specifies the characteristics of solid parquet elements with grooves and/or
tongues for internal use as flooring. This standard is not applicable to panels made from elements for
which a separate standard is in course of preparation.
This standard covers elements with or without surface treatment.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this European Standard only when incorporated in it by amendment or revision. For undated

5 Specific product requirements
5.1 Wood species
A list of the most commonly used species for parquet elements as described in this standard is given in
Annex A.
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 1310 (knots assessed according to the general method of
4.1 in EN 1310:1997). Biodeterioration is measured according to EN 1311.
A classification with three appearance classes is specified, designated
, D and .
A classification named "Free class" is based on the principles laid out in Annex B.
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.
5.2.2 Rules for the most commonly used species
