Foreword
This document (EN 13488:2002) 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by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by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 annexes A and B are informative. Annex C 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 standard is one of a series of standards about wood flooring and wood panelling and cladding.
This standard specifies the characteristics of mosaic parquet. It is based upon current dimensional standards used in
the industry together with functions which have been verified by test.
A large amount of knowledge exists about mosaic parquet 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 floor is mainly influenced by species, classification and the pattern.
1 Scope
This European Standard specifies the appearance classes, dimensions and other characteristics of solid wood
mosaic parquet fingers, component squares, mosaic parquet laying units and mosaic parquet panels, finished or
unfinished, for internal use as flooring.

3.1
mosaic parquet finger
element of solid sawn wood of small dimensions and rectangular shape, having flat edges
[EN 13756:2002]
3.2
component square
mosaic parquet fingers of same dimensions, assembled edge to edge to form a square
NOTE The size of the square is equal to the length of the mosaic parquet fingers.
3.3
mosaic parquet laying unit
pre-assembled laying unit made up from mosaic parquet fingers which are assembled in a certain way in order to
form a repeatable pattern, for example squares or other designs
3.4
mosaic parquet panel
pre-assembled laying unit made up from component squares of the same dimensions placed edge to edge, laid in
a chequered pattern
4 Specific product requirements
4.1 Wood species and patterns
Species shall be specified.
A list of the most commonly used species for mosaic parquet as described in this standard is given in Annex A.
Unless otherwise agreed, mosaic parquet panels shall be assembled from component squares as shown in
Figure 1. Some other patterns are shown in Annex B.

4.2 Appearance
4.2.1 General rules
Tables 1 to 3 define the classification relating to appearance rules for the face and for the non-visible parts (back and
edges) of a mosaic parquet finger of the most commonly used species for mosaic parquet 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 C.
The face shall include all the visible surface of the element.
The face shall be free of bore holes and the wood shall be sound. Growth rings as well as medullary rays are
permitted.
4.2.2 Rules for the most commonly used species
4.2.2.1 Quercus spp. (oak) and tropical hardwoods

The free class covers any species which may be used for parquet and for which hardness HB has a minimum mean
value of 10 N/mm . Hardness shall be measured according to EN 1534. The free class covers any classification which
the producer wishes to offer or which is requested by the buyer. The proportions or limits of features shall be
specifically indicated in the producer's literature/data sheets, in conformity with Annex C and stated according to Table
