European foreword
This document (EN 16094:2021) has been prepared by Technical Committee CEN/TC 134 “Resilient,
textile and laminate floor coverings”, the secretariat of which is held by NBN.
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 December 2021 and conflicting national standards
shall be withdrawn at the latest by December 2021.
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 16094:2012.
In comparison with the previous edition, the following technical modifications have been made:
— addition of a method C for evaluation of polishing effect on mat laminate flooring surfaces;
— introduction of a reference HPL for calibration of the respective scrub materials.
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, Turkey and the
United Kingdom.

1 Scope
This document specifies a test method for the micro-scratch resistance with two procedures (A and B)
and a test method for polishing resistance (procedure C) which can be used for all types of laminate
floor coverings. The resistance to polishing is related to mat surfaces.
2 Normative references

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.

4 Principle
The sample is fixed on a horizontal table. A circular scrub material fixed on a holder impacts on the
sample with a defined load. Table and holder are 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 sample is exposed to the scrub material for a predetermined number of rubs. The changes of the
surface are determined by gloss measurement and visual assessment.
5 Apparatus and materials
5.1 Martindale tester
The Martindale tester shall be as described in EN ISO 12947-1 with the following exceptions:
— the “abrading table” is the table for the sample;
— the “clamping ring and mechanism” is not necessary;
— the “specimen holder” is the holder for the scrub material;
— the “loading pieces” are not necessary.
5.2 Holder for scrub material
The holder for scrub material shall be as described in EN ISO 12945-2, with the following exceptions:
— version 1: the rubber retaining ring is not required. This assembly consists of spindle, scrub holder
and small ring weight. The total mass of this assembly is (413 ± 2) g (nominally called 4N);
— version 2: the assembly according to version 1, however the small ring weight is replaced by the
large weight. The total mass of this assembly is (612 ± 2) g (nominally called 6N).
5.3 Diffuse light source
Light source with artificial light providing evenly diffused light giving an illumination on the test surface
of (1 200 ± 400) lx.
5.4 Reflectometer
For gloss measurement with 3 angle measurement geometry as described in EN ISO 2813.
5.5 Positioning device
For gloss measurement on the same position before and after the test with 4 measurement points.
An example of a positioning device is shown in Figure 1.

5.6 Scrub materials
The scrub material shall be a nylon web imbedded with alumina abrasive. Three types of scrub
materials (very fine, medium fine and ultra-fine) are to be used. The scrub materials shall be cut or
stamped on a diameter of (89 ± 1) m
