This Technical Specification (CEN/TS) was approved by CEN on 18 January 2016 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.

European foreword
This document (CEN/TS 16611:2016) has been prepared by Technical Committee CEN/TC 207
“Furniture”, the secretariat of which is held by UNI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes CEN/TS 16611:2014.
Compared to CEN/TS 16611:2014, the following modification has been made:
— in 8.2.2.1 “2 or 3” is replaced by “3 or 4”.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
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.
1 Scope
This Technical Specification specifies a method for the assessment of the surface resistance to
microscratching and relates to rigid surfaces of all finished products regardless of materials.
Method A is suitable for all types of surface coatings and coverings except for lacquers with pearly or
metallic effects.
Method B is suitable for all types of surface.
It does not apply to finishes on leather and fabrics.
The test is intended to be carried out on a part of finished furniture, but can 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 is 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. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN ISO 2813, Paints and varnishes - Determination of gloss value at 20°, 60° and 85° (ISO 2813)
EN ISO 12945-2, Textiles - Determination of fabric propensity to surface fuzzing and to pilling - Part 2:
Modified Martindale method (ISO 12945-2)

Part 1: Martindale abrasion testing apparatus (ISO 12947-1)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
test surface
part of the test panel
3.2
test panel
panel including the test surface
Note 1 to entry: It can be cut from a finished item of furniture or it can be a separate panel produced in the
same manner as the finished item of furniture.
3.3
test area
part of the test surface effected by the scrub material (5.6)
3.4
rub
one revolution of the two outer drives of the Martindale tester
3.5
cycle
completion of all the translational movements tracing a Lissajous figure comprising 16 rubs
Note 1 to entry: This comprises of 16 revolutions of the two outer drives and 15 revolutions of the inner drive
of the Martindale tester.
3.6
lissajous figure
figure created by movement which ranges changes from a circle gradually narrowing ellipses, until it
becomes a straight line, from which progressively widening ellipses develop, in a diagonally opposite
direction before the pattern is repeated
4 Principle
The test surface shall be fixed on a horizontal table. A circular scrub material fixed on a holder impacts
on the test surface with a defined load. Table and holder shall be moved perpendicular to each other, in
a translational movement, with defined frequencies, tracing a Lissajous figure. The holder is
additionally freely rotatable around its own axis perpendicular to the horizontal plane.
The test surface is exposed to the scrub material for a predetermined number of rubs. The changes of
the surface are determined by gloss measurement or visual assessment.
