This document (EN 13489:2002) has been prepared by Technical Committee CEN /TC 175, "Round and sawntimber" 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by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest byJune 2003

In this European Standard annex A is informative and annex B is normative

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries 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

This European Standard is one of a series of standards about wood flooring and wood panelling and cladding.This standard specifies the characteristics of multi-layer parquet It is based upon current dimensional standards used

in the industry and other characteristics together with functions which have been verified by test

A large amount of knowledge exists about multi-layer parquet and values for product characteristics are attested bylong 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

For the purposes of this European Standard, the terms and definitions given in EN 13756 and the following apply

A list of the most commonly used species for parquet as described in this standard is given in Annex A.

4.2 Typical types and patterns

Figures 1 to 4 give examples of common types/patterns of multi-layer parquet elements

Figures 2 and 3 are examples of types which are intended for patterned installation

Elements in Figure 3 are usually of smaller dimensions

Figure 1 — Type 1

Figure 2 — Type 2

Figure 3 — Type 3 (an element intended for patterned installation)

4.3 Finishing

The surface treatment used and any artificial change of the natural wood colour shall be stated in the productdescription

immediately after installation

4.4 Appearance

4.4.1 General rules

Tables 1 to 4 define the classification relating to appearance rules for the face and for the non-visible parts (backand edges) of an element of the most commonly used species for multi-layer 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 EN1310:1997) Biodeterioration is measured according to EN 1311

A classification with three appearance classes is specified, designated
, ∆ and 

A classification named « Free class » is based on the principles laid out in Annex B

The material used for the top layer shall be selected hardwood or softwood, fresh and sound without rot, fungus,mould or insect damage There will be variations from strip to strip, but the total impression of the installed floorshall show a homogeneous character of each classification

To allow for unavoidable classification differences, 3 % of the strips in a batch may be from other classes Anyadditional strips from other classes are allowed as long as the general impression of the floor is not disturbed.Multi-layer parquet with a mosaic-like pattern shall be classified according to EN 13488
