Surfaces for sports areas - Multi-sports floor systems for indoor use - Test method for determination of rotational friction

This European Standard specifies a method for the determination of the friction between multi-sports floor systems excluding synthetic turf for indoor use and a rotating foot with a vertical load. The method is applicable to tests carried out in the laboratory and on site.

Sportböden - Synthetische Sportböden für den Innenbereich - Bestimmung der Drehreibung

Diese Europäische Norm legt ein Verfahren für die Bestimmung der Reibung zwischen synthetischen Sportböden für den Innenbereich (außer Kunstrasen) und einem Drehfuß mit vertikaler Last fest. Das Verfahren kann sowohl im Labor als auch vor Ort angewendet werden.

Sols sportifs - Systèmes de sols multisports pour utilisation en intérieur - Méthode d’essai de détermination de la glissance en rotation

La présente Norme européenne spécifie une méthode de détermination du frottement entre les systèmes de sols multisports destinés à un usage en intérieur, à l’exclusion des gazons synthétiques, et un pied rotatif soumis à une charge verticale. Cette méthode peut être utilisée pour des essais réalisés en laboratoire ou sur site.

Podloge za športne dejavnosti - Sistemi večnamenskih podlog za notranjo uporabo - Preskusna metoda za ugotavljanje odpornosti proti trenju pri vrtenju

Ta evropski standard določa metodo za ugotavljanje trenja med poljubno športno površino in vrtečo se nogo pri vertikalni obremenitvi. Metoda se uporablja za preskušanja v laboratoriju ali na mestu uporabe.

EN 14903:2018 (E) 4 1 Scope This European Standard specifies a method for the determination of the friction between multi-sports floor systems excluding synthetic turf for indoor use 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 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 660-1, Resilient floor coverings — Determination of wear resistance — Part 1: Stuttgart test EN 60051 (all parts), Direct acting indicating analogue electrical measuring instruments and their accessories (IEC 60051) EN ISO 291, Plastics - Standard atmospheres for conditioning and testing (ISO 291) ISO 21948, Coated abrasives — Plain sheets 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 friction coefficient horizontal force between the test foot and the sports surface (resulting from the measured torque) divided by the vertical load on the foot during rotation Note 1 to entry: See 4.6 to determine the coefficient of friction. 3.2 vertical load vertical force exerted on the sports floor by the test foot 3.3 torque result of forces occurring at the eccentrically positioned test soles when the test foot rotates onto the sports surface under vertical load Note 1 to entry:

The torque equals the force multiplied by the distance of the skids from the centre of the test foot. 4 Determination of rotational friction 4.1 General 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. SIST EN 14903:2018
