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.
Dimensions in millimetres

4.4 Assessment template
Tool with defined areas [mm ], e.g. a transparent film with printed areas.
NOTE A suitable template is the “Size estimation chart”, product code 0109DIRTT, available from TAPPI,
15 Technology Parkway South, Suite 115, Peachtree Corners, Atlanta, GA 300922910, USA, tel. +1 770 446 1400,
fax +1 770 446 6947.
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.

4.7 Rating code scale
The classification is based on the principle of the figures presented in Annex B, see Figure B.1 to B.8.
5 Testing and assessment
5.1 General
Assessment procedures A and B are determined to be performed in the incoming and outgoing
inspection at the factory.
Assessment procedure C is determined to be performed on site in an installed condition.
The assessment shall be performed on furniture surfaces that have been cleaned with the cleaning
solution according to 4.1.
The surfaces shall dry off after the cleaning, without rubbing the surface.
5.2 Procedure A for visual assessment of furniture components at the incoming and
outgoing inspection in the factory
The furniture component shall be cleaned with the cleaning solution according to 4.1 (1 day old at
most) before the visual assessment. The concerned surface shall be lightly wiped with a clean, soft,
absorbent cloth (no microfibre) before the inspection.
The surface to be assessed shall be inserted in the holder (4.3) and assessed by an experienced
inspector in keeping with the inspection conditions of Table 1 and under the lighting device (4.2), as
illustrated in Figure 1.
