Visual assessment of furniture surfaces

To develop a standard or technical report describing a method to assess the surface damage after carrying out tests intended for furniture surfaces. This visual assessment will be used to evaluate the results from these tests and will be introduced in the appropriate standards by a reference to the new technical report or standard.

Visuelle Bewertung von Möbeloberflächen

Dieses Dokument legt visuelle Bewertungsverfahren für das Erscheinungsbild von Möbeloberflächen im Hinblick auf Oberflächendefekte sowie Farb  und Glanzabweichungen fest.
Es ist nicht auf konstruktive Merkmale oder geometrische Abmessungen, z. B. Parallelität von Kanten, anwendbar.
Diese Norm ist auf alle Möbeloberflächen mit Ausnahme von textilen Oberflächen und Lederoberflächen anwendbar.
Sie gilt für Wareneingangs  und Warenausgangsprüfungen sowie lokale Bewertungen.

Evaluation visuelle de la surface des meubles

Le présent document définit des modes opératoires d’évaluation visuelle de l’aspect des surfaces de meubles au regard des défauts de surface, des variations de couleur et des variations de brillance.
Elle ne s’applique pas aux caractéristiques de construction ou aux dimensions géométriques, comme le parallélisme des chants.
La présente Norme s’applique à toutes les surfaces des meubles à l’exception des surfaces textiles ou en cuir.
Elle s’applique aux inspections de réception et d’expédition de marchandises, ainsi qu’aux évaluations locales.

Vizualno ocenjevanje površine pohištva

Cilj je oblikovati standard ali tehnično poročilo, ki opisuje metodo za ocenjevanje poškodb površin po izvedbi preskusov, predvidenih za površine pohištva. Vizualno ocenjevanje se bo uporabljajo za vrednotenje rezultatov teh preskusov in bo predstavljeno v ustreznih standardih s sklicem na novo tehnično poročilo ali standard.

3.7
assessed surface
part of the furniture component to be assessed
3.8
repeat

4 Assessment equipment
4.1 Cleaning solution
15 ml/l of the cleaner in water with the following cleaner composition:

a) 12,5 % (m/m) of a primary or polymeric sodium (C10 to C14) alkylaryl sulphonate

[CAS 25155-30-0];

b) 12,5 % (m/m) of a polyethoxylated primary or secondary (C8 to C16) alcohol derivative with 5 to

15 ethoxyl groups with a cloud point of 25 °C to 75 °C in 1 % (m/m) aqueous solution (the

determination of the cloud point is specified in ISO 1065:1991) [CAS 9005-67-];
c) 5,0 % (m/m) of ethanol (96 % aqueous solution);
d) 70 % (m/m) de-ionized or distilled water.

Instead of this described cleaning solution, a commercial cleaning solution recommended by the

manufacturer can be used. In this case, it shall be mentioned in the test report.

4.2 Lighting

Artificial light source with a colour temperature of (6 500 ± 200) K (CIE standard illuminants D65 light).

4.3 Holder for furniture components

Device for placing the object to be inspected at an angle of 30° ± 3° and in a manner ensuring that the

assessed surface is exposed to a light intensity of 1,000 lx to 2,000 lx (Figure 1), measured in the centre

of the holder in horizontal position.

4.5 Light box
The light box provides a “daylight” by bulb or tube or LED (see Figure 2).
The light shall be even enough to ensure the absence of under illuminated zones.

The light behind the test pattern shall be without a black area within the light source.

The lightbox can be a negatoscope or other equipment with a diffuse and homogeneous light. The light

box with the test pattern shall send an image with a clear contrast on the mirror. The distinction of

image shall be without distorsion or dullness on a plane mirror.

NOTE Suitable devices are e.g. NBX1 negatoscope by ELLA LEGROS or Glossinspector by MHanser.

Figure 2 — Light box
4.6 Test pattern

The test pattern (see Figure 3) has empty squares (10,0 ± 0,2) mm side, separated by metal bars of

(2,0 ± 0,1) mm.
The overall dimension shall be at least of 15 columns and 20 lines of squares.

The test pattern shall stay plane on the light box or printed on the lightbox screen.

These are examples of suitable products available commercially. This information is given for the

convenience of users of this document and does not constitute an endorsement by CEN of this product.
