BS PD CEN/TS 15901-14:2016描述了一种测定车辆湿滑阻力的方法 通过测量纵向摩擦系数LFCN得到表面。还使用了所描述的方法 测定冰雪覆盖表面的防滑性。该方法通过使用电制动试验轮测量路面的摩擦系数。ViaFriction可以在以下模式下运行:固定滑移:滑移率固定。滑移率可以设置为1%到75%之间的值。固定滑动速度: 滑动速度是固定的。打滑速度必须低于车辆速度。可变滑移率:试验轮在0%至75%的滑移率下制动，记录F 30、F 60和滑移率 比率/摩擦曲线。试验过程中，在受控速度条件下，将试验轮胎拖过预湿路面 轮胎与运动方向平行，与路面垂直。防滑性 冬季道路的测量不需要预湿路面。为了确定路面的宏观纹理，可以添加激光系统。 这个系统是 放置在牵引车前面，以测量宏观纹理（平均轮廓深度-MPD） 在干燥路面上，在与防滑性测量相同的路径上进行。标准 EN ISO 13473-1中描述了该测量和装置。交叉引用:EN ISO 13473-1ISO 13473-1ISO 13473-2ASTM 1551ISO 13473-3购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS PD CEN/TS 15901-14:2016 describes a method for determining the wet road skid resistance of a surface by measurement of the longitudinal friction coefficient LFCN. The described method is also used to determine the skid resistance on a surface covered by ice or snow.The method provides friction coefficient measurements of the pavement by using an electrically braked test wheel.ViaFriction can operate in the following modes:Fixed slip: The slip ratio is fixed. The slip ratio can be set to a value from 1 % to 75 %.Fixed slip speed: The slip speed is fixed. The slip speed has to be lower than the vehicle speed.Variable slip: The test wheel is braked from 0 % to 75 % slip ratio recording F 30, F 60 and the slip ratio/friction curve.The test tyre is dragged over a pre-wetted pavement under controlled speed conditions while the test tyre is parallel to the direction of motion and perpendicular to the pavement. Skid resistance measurement on winter roads do not require pre-wetted pavement.To determine the macrotexture of the pavement surface a laser system can be added. This system is placed in front of the towing vehicle in order to measure the macrotexture (mean profile depth - MPD) on dry pavements and on the same path as the skid resistance measurement is done. The standard for this measurement and the device is described in EN ISO 13473-1.Cross References:EN ISO 13473-1ISO 13473-1ISO 13473-2ASTM 1551ISO 13473-3All current amendments available at time of purchase are included with the purchase of this document.
