European foreword
This document (EN 13629:2020) 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 September 2020, and conflicting national standards shall
be withdrawn at the latest by September 2020.
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 13629:2012.
The main changes with respect to the previous edition EN 13629:2012 is the correction of subclause 4.4
Moisture content – misleading link is removed and range of moisture content adopted.
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,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
1 Scope
This document specifies the characteristics of individual hardwood boards and pre-assembled hardwood
boards with grooves and/or tongues for internal use as flooring. This document covers hardwood boards
with or without surface coating.
This document does not cover solid parquet elements. (See Annex C).

3.1
solid individual hardwood board
wide and generally long solid (single layer) hardwood element which has parallel sides, is machined to a
regular thickness and profile(s) with profiled edges and ends and is capable of being assembled with
other analogous elements (see Figure 1)
Figure 1 — Individual hardwood board
3.2
solid pre-assembled hardwood board
wide and generally long solid (single-layer) hardwood element, pre-assembled from several strips in
length and width by dovetailing, edge gluing and end jointing which has parallel sides, is machined to a
regular thickness and profile(s) with profiled edges and ends, and is capable of being assembled with
other analogous elements (see Figure 2)

3.3

smallest single item forming the pre-assembled board
3.4
thickness above the groove
thickness between the face and any discontinuity such as a change in the profile (excluding chamfering),
a groove/glue pocket or a glue line (excluding the glue line of dove-tail joints)
4 Specific product requirements
4.1 Wood species
A list of the most commonly used hardwood species for wood flooring as described in this standard is
given in Annex A.
4.2 Finishing
The product may be delivered with a factory applied surface coating which allows the product to be taken
into use immediately after installation. The surface treatment used and any artificial change of the natural
wood colour shall be stated in the product description.
4.3 Appearance
4.3.1 General rules
Tables 1 to 4 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 in
EN 1309-3). Bio deterioration, permitted only for certain appearance classes (see Tables 1 to 4) 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 B.
The face shall include all the visible surface of the element.
Any continuous glue joint which allows renovation without significantly changing the appearance or the
functional characteristics is acceptable.
4.3.2 Classification
The class shall be specified.
The decorative appearance of each species will vary with class.
NOTE The fact that some classes allow many natural characteristics is important when specifying decorative
appearance.
4.3.3 Rules for the most commonly used species
4.3.3.1 Quercus spp. (oak)
Rules for oak are given in Table 1.
