4 Requirements
4.1 General
All wood veneer floor coverings shall comply with the general requirements given in Table 1 and Table 2.
Wood veneer floor coverings with film-forming coating and printed surfaces shall comply with the
classification requirements given in Table 3. The values given in this Table take account of uncertainties
due to variations in the application of finishes and of those described in the test method in Annex D and
Annex E.
4.2 General requirements
The nominal dimensions shall be declared by the manufacturer at a given humidity.
The wood used for the top layer are hardwood or softwood species and shall be free from decay and
insect attack. Variations of colour can occur under the influence of light.
Uncovered surfaces will change their natural appearance depending on the level of use. A surface
treatment is necessary to protect the veneer surface after installation.
Low use frequency combined with climate changes may lead to slight creaking effects on floated installed

7 Measures to extend the life span
7.1 General
The manufacturer’s instructions shall be followed when carrying out the work. It is important to
emphasize that any surface treatment carried out after installation may influence or change the original
appearance and technical properties.
7.2 Maintenance
Basic cleaning and/or the application of surface treatment techniques can reduce existing signs of use
and maintain and improve the appearance and usage properties.
These operations are possible several times.
The process of retaining the appearance of the face and its treatment is done either by cleaning, reoiling,
rewaxing, refreshing or application of specialist products.
NOTE This is meant to be done within the expected service life.
7.3 Local repair
Depending on the type of surface treatment, a local repair can be carried out either by replacing elements
or by processing the areas to be repaired. When performed properly, no significant reduction of
performance or top-layer-thickness is caused. A local repair is possible several times. See also reparation
(3.16).
7.4 Renovation and refurbishment
In case the product built-up allows renovation or refurbishment, this can be carried out by appropriate
methods (by example: sanding to bare wood, sanding a finishing, brushing if necessary, applying a
finishing, and therefore creating a new surface).
prEN 14354:2024 (E)
This might change properties of the flooring, e.g. structure, coloration, reaction to fire. If, due to deep
damage to the wood structure, an excessive amount has to be removed, a new renovation or
refurbishment by sanding may no longer be possible.
NOTE 1 For technical reasons, surface structure, stained surfaces, multiple colours, digital printings, bevelled
products, etc. will change after renovation and refurbishment since the surface will be sanded and retreated in the
renovation and refurbishment process.
NOTE 2 As wood is a hygroscopic material, it is influenced by fluctuations in humidity, as in content of water in
the surrounding air, better known as Relative Humidity (RH). Changing of relative humidity influence the moisture
