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.

1 Scope
This document specifies a method for the assessment of the surface resistance to penetrating 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.

≥ 0,30 mm
3.6.2

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

preliminary assessments of the scratching resistance (method A)
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

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).
The width of the scratching trace is the result of the assessment of the series of scratches produced by
the tip.
4.2 Apparatus and materials
4.2.1 Test apparatus
4.2.1.1 Equipment for linear, without hand movement of the scratching tip or the test surface,
according to the principle of EN ISO 1518-1.
4.2.2 Equipment parameters
Technical parameters of the apparatus shall be as specified in Table 1.
Table 1 — Technical parameters
Parameter Description/values
Tip/test surface movement Linear
Load range (N) 1,0 to 20,0
Increment of load (N) 1,0 ± 0,1
Speed of the tip's/test surface movement (mm/s) 20 ± 10
Travel length of the tip or test surface (mm) Minimum 20
4.2.3 Scratching tip
Scratching tip made of diamond, with a radius (R) of (0,30 ± 0,01) mm.
The coupling between the spherical part of the tool and the truncated cone section shall allow the width
of the trace produced by the tool on the test area to be higher than 0,30 mm, without disturbing this
truncated cone section.
An example of this tool is shown in Figure 1.
The tip shall be
