CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TS 15186:2005. Regarding the significant technical changes that have been made in this new edition of EN 15186, see the informative Annex B. According to the CEN/CENELEC Internal Regulations, the national standards organizations 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, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

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 scratches that may only 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 The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

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 3.4.1 method A needle with a point of defined geometry SIST EN 15186:2012

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 (Newtons) 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. SIST EN 15186:2012

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 mounted in the holder with the flat part on the leading side of the shank facing the worki
