1.1 本试验方法包括用指定的全尺寸汽车轮胎测量铺装表面的防滑性。 1.2 该测试方法利用表示锁定测试轮在恒定载荷下以恒定速度在湿路面表面上拖动，同时其主平面平行于其运动方向并垂直于路面时的稳态摩擦力的测量值。 1.3 测量的值代表用本文所述的设备和程序获得的摩擦特性，并且不一定与通过其他路面摩擦测量方法获得的那些值一致或直接相关。这些值旨在用于评估路面相对于其他路面的防滑性或用于评估路面的防滑性随时间的变化。这些值不足以确定在潮湿或干燥路面上停车车辆所需的距离。它们也不足以确定车辆失去控制的速度，因为这些确定还需要峰值和侧向力摩擦。 1.4 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。有关具体的安全注意事项，请参见第节 5 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This test method covers the measurement of skid resistance of paved surfaces with a specified full-scale automotive tire. 1.2 This test method utilizes a measurement representing the steady-state friction force on a locked test wheel as it is dragged over a wetted pavement surface under constant load and at a constant speed while its major plane is parallel to its direction of motion and perpendicular to the pavement. 1.3 The values measured represent the frictional properties obtained with the equipment and procedures stated herein and do not necessarily agree or correlate directly with those obtained by other pavement friction measuring methods. The values are intended for use in evaluating the skid resistance of a pavement relative to that of other pavements or for evaluating changes in the skid resistance of a pavement with the passage of time. The values are insufficient to determine the distance required to stop a vehicle on either a wet or a dry pavement. They are also insufficient for determining the speed at which control of a vehicle would be lost, because peak and side force friction are also required for these determinations. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific safety precautions, see Section 5 . 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
