identical text or by endorsement, at the latest by January 2020, and conflicting national standards shall
be withdrawn at the latest by January 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the

1 Scope
This document defines visual assessment procedures for the appearance of furniture surfaces with
regard to surface defects and colour and gloss variations.
It is not applicable to constructive features or geometric dimensions, e.g. parallelism of edges.
This standard is applicable to all furniture surfaces except textile and leather surfaces.
It applies to the incoming and outgoing goods inspections, as well as local assessments.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
normal position
position of the furniture item when used as intended
3.2
visual assessment
assessment of the furniture surface under specified conditions
3.3
overall impression
regularity in the arrangement of individual items of furniture that belong together and of their parts in
relation to one another, or of individual parts of an item of furniture, from a distance according to the
size of the furniture component
3.4
detailed impression
regularity of a surface of furniture items from a short distance (from 0,25 m to 1 m) according to the
intended use of the furniture
3.5
flaw
any kind of visible damage on furniture surfaces that stands out from its surroundings and impairs the
overall impression
Note 1 to entry: The flaw catches the attention of the viewer, thereby leading to its perception as disruptive.
EXAMPLE Scratches, occlusions.
3.6
furniture component
element subjected to visual inspection
3.7
assessed surface
part of the furniture component to be assessed
3.8
repeat
repeating, area-filling surface design element
EXAMPLE Wood decor, surface embossing.
3.9
observer
technician who carries out the assessment fulfilling the requirement specified in EN ISO 3668:2001
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
Figure 1 — Visual assessment principle for furniture components
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.
