1.1 本试验方法包括使用连续读数、固定滑动技术测量路面或其他交通表面的防滑性。 1.2 本试验方法涵盖在小于100%的条件下获得的制动轮测量值 % 滑倒它不包括侧力测量。 1.3 该测试方法提供了沿测试表面一条轨道全长的防滑性记录，并能够获得指定测试段的平均值。 1.4 本试验方法用于在各种情况下测量各种表面的防滑性。 因此，有许多不同的连续读数、固定滑动测量设备（CFME）设计，以及许多不同的测试程序来控制其使用。 1.5 本试验方法不试图详细说明这些不同的设备和程序，但规定了基本的通用原则。 1.6 CFMEs通过在选定滑移率下运行的测试轮胎和测试表面之间创建和测量摩擦力来发挥作用。不同类型的CFME不一定在其特定测试轮胎和公共测试表面之间产生相同的摩擦力，也不一定使用相同的方法测量该摩擦力。 1.7 CFME测量是在选定的稳定测试速度下获得的。此速度可能因应用而异。 1.8 测试表面可能被污染或清洁干燥。如果清洁干燥，则测得的水量通常沉积在测试轮正前方的表面上。 1.9 测量装置可以内置在车辆、由车辆牵引的拖车或手动推动的装置中。 1.10 以国际单位制或英寸表示的数值- 磅单位应单独视为标准单位。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.11 本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 安全预防信息包含在第节中 7. . 1.12 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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 CFME用于测量跑道、道路和各种其他交通表面的防滑性。 这些测试可能包括运行测试，以在当前条件下立即评估防滑性，或在标准化条件下进行常规测试，其中包括在测试轮胎前施加精确量的水。 5.2 标准测试速度和标称水膜厚度符合国家或国际机构标准、CFME类型和测试应用。中给出了一些典型应用示例 附录X1 .

1.1 This test method covers the measurement of the skid resistance of a pavement or other trafficked surface using the continuous reading, fixed-slip technique. 1.2 This test method covers braked wheel measurements obtained with less than 100 % slip. It does not cover side force measurements. 1.3 This test method provides a record of the skid resistance along the whole length of one track of the test surface and enables averages to be obtained for specified test segments. 1.4 This test method is used to measure skid resistance on a wide variety of surfaces in a wide variety of circumstances. Consequently, there are many different designs of continuous reading, fixed-slip measuring equipment (CFME) and as many different test procedures governing their use. 1.5 This test method does not attempt to detail these different equipment and procedures but does set out the essential common principles. 1.6 CFMEs function by creating and measuring a frictional force between a test tire operating at a selected slip and the test surface. Different types of CFME do not necessarily create the same frictional force between their particular test tire and a common test surface and do not necessarily use the same method to measure this frictional force. 1.7 CFME measurements are obtained at a selected steady test speed. This speed may vary according to the application. 1.8 The test surface may be contaminated or clean and dry. If it is clean and dry, a measured amount of water is normally deposited on the surface just in front of the test wheel. 1.9 The measuring apparatus may be built into a vehicle, built into a trailer that is towed by a vehicle, or built into a device that is manually pushed. 1.10 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. 1.11 This standard may involve hazardous materials, operations, and equipment. 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. Safety precautionary information is contained in Section 7 . 1.12 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. ====== Significance And Use ====== 5.1 CFMEs are used to measure skid resistance on runways, roads, and various other trafficked surfaces. These tests may comprise operational testing, performed to obtain an immediate assessment of skid resistance in current conditions or routine testing in standardized conditions which include the application of a precise amount of water in front of the test tire. 5.2 Standard test speeds and nominal water film thicknesses are according to national or international agency standards, the type of CFME, and the test application. Some examples of typical applications are given in Appendix X1 .
