European foreword

This document (prEN 16094:2020) has been prepared by Technical Committee CEN/TC 134 “Resilient,

textile and laminate floor coverings”, the secretariat of which is held by NBN.
This document is currently submitted to Enquiry.
This document will supersede 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.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

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.
