European foreword
This document (EN 15186:2024) has been prepared by Technical Committee CEN/TC 207 “Furniture”,
the secretariat of which is held by UNI.
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 September 2024, and conflicting national standards shall
be withdrawn at the latest by September 2024.
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.
This document supersedes EN 15186:2012.
Compared with EN 15186:2012, the following modifications have been made:
a) subclauses of Clause 4, Linear method (method A), revised;
b) subclauses of Clause 5, Circular method (method B), revised;
c) Annex B deleted; the significant changes in the revised edition are now given in the European
foreword;
d) Bibliography updated.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies a method for the assessment of the surface resistance to different kinds of visible
scratches. It relates to the rigid surfaces of all finished products, regardless of their material.
It does not apply to finishes on leather and fabrics.
Method A is suitable for all types of surface coatings and coverings except for melamine faced boards
(according to EN 14322) and HPL (according to EN 438-1). It simulates measurable penetrating and/or
deforming scratches.
Method B is suitable for all types of surfaces. It simulates first visible traces (e.g. scratches, marks) that
can also be a change in the gloss.
The test is intended to be carried out on a part of finished furniture. It can, however, be carried out on
test panels of the same material, finished in an identical manner to the finished product, and of a size
sufficient to meet the requirements of the test.
It is essential that the test be carried out on unused surfaces.
2 Normative references

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 https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
test surface
part of the test panel
3.2
test panel
panel including the test surface
Note 1 to entry: The panel may be cut from a finished item of furniture or it may be a separate panel produced in
the same manner as the finished item of furniture.
3.3
test area
part of the test surface under the equipment, where the measurement is carried out
3.4
scratching tip
tool with a point of defined geometry
Note 1 to entry: See 4.2.3 for method A.
Note 2 to entry: See 5.2.1.6 for method B.
3.5
scratching trace
3.5.1
method A
visible and measurable scratch on the tested surface which is produced under the specified load of the
scratching tip; the shapes of the traces’ edges can be different depending on the substrate and coating
type as shown in Table 2
3.5.2
method B
first visible traces on the tested surface (e.g. scratches, marks) which may also be a change in the gloss
3.6
scratching resistance
3.6.1
method A
minimum load, in N, applied to the scratching tip, which produces a measurable trace of the width (W) of
≥ 0,30 mm
3.6.2
method B
minimum load, in N, applied to the scratching tip, which produces a continuous visible trace in at least six
of eight slots of the template
3.7
preliminary assessments of scratching resistance (method A)
assessment of minimum load causing the specified width of scratch on test surface
3.8
intermediate assessment of scratching resistance (method A)
mean value of preliminary assessments of test surface
3.9
final result of scratching resistance (method A)
mean value of intermediate assessments of three test surfaces
Note 1 to entry: See Figure A.2 in the informative Annex A.
4 Linear method (method A)
4.1 Principle
Surface scratching resistance is defined as the minimum load in N (Newton) applied to the tip with
specified geometry, which produces a specified scratch width (see 4.4.2).
