Surfaces for sports areas - Determination of rotational friction

This European Standard specifies a method for the determination of the friction between any type of indoor sports surface and a rotating foot with a vertical load.
NOTE   This method simulates the load exerted by an athlete in a rotating movement on the floor.

Sportböden für Innenbereiche - Bestimmung der Drehreibung

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Reibung zwischen einem beliebigen Sportbodentyp und einem Drehfuß mit vertikaler Last fest. Das Verfahren kann sowohl im Labor als auch vor Ort angewendet werden.

Sols sportifs - Détermination de la glissance en rotation

La présente Norme européenne spécifie une méthode permettant de déterminer la glissance entre un type quelconque de sol sportif et un pied en rotation soumis à une charge verticale. Cette méthode est applicable aux essais effectués en laboratoire et sur site.

Foreword
This document (prEN 14903:2005) has been prepared by Technical Committee CEN/TC 217 “Surfaces for
sports areas”, the secretariat of which is held by BSI.
This document is currently submitted to the second CEN Enquiry.
1 Scope
This European Standard specifies a method for determination of the friction between any type of sports
surface and a rotating foot with a vertical load. The method is applicable to tests carried out in the laboratory
and on site.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this European Standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies (including amendments).
EN 60051, Direct acting indicating analogue electrical-measuring instruments and their accessories (all Parts)
EN ISO 291, Plastics – Standard atmospheres for conditioning and testing
EN 21948, Coated abrasives – Plain sheets
3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
friction coefficient
horizontal force between the test foot and the sports surface (derived from the measured torque) divided by
the vertical load on the foot during rotation (see clause 9)
3.2
vertical load
vertical force exerted on the sports surface by the test foot
3.3
torque
result of forces occurring at the eccentrically positioned test soles when the test foot rotates onto the sport
surface under vertical load
NOTE The torque equals the force multiplied by the distance of the skids from the centre of the test foot.

prEN 14903:2005 (E)
4 Principle
Friction is measured by allowing a circular test foot, with attached test soles, to rotate on the sports surface
under a vertical load. The friction resistance is calculated by recording the torque when the rotating test foot
touches the test surface and then slides in rotation until the foot comes to a complete stop. From this the
coefficient of friction, µ, is calculated as described in clause 9.
5 Sampling
5.1 Laboratory testing
The supplied test sections shall be large enough to carry out tests in at least three different places. For area-
elastic floors, only the top layers (wooden surface, PUR coating, PVC covering or linoleum) need to be used in
the test.
For point-elastic and mixed-elastic floors, the total system shall be tested. For combi-elastic floors, a minimum
of the top layer, including the elastic layer, shall be tested.
If necessary, the test pieces shall be glued to a stiff panel such as plywood to achieve a firm and stable
support. The floor
