Device for the evaluation of at least one friction property of a ski wax against the surface of snow in a skiing track, comprising a disc carried by a stand and having a substantially planar working surface, on which a layer of wax that is to be evaluated is applied, members for the pressing of the disc by a preselected force against the snow surface and driving members for the driving of the disc in relation to the snow surface. The driving members comprise an electric motor having a known relationship between the electric power consumption of the electric motor and the braking power of the disc and that means are provided for the readout of the electric power consumption of the motor, at least in the beginning of the displacement of the disc in relation to the snow surface. |
