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
