1.1 该测试方法包括使用通常称为μ m计的设备测量铺设表面的侧向力摩擦。 2 1.2 该测试方法利用通过在路面上以恒定速度拉动包含与运动方向成角度的两个自由旋转的测试轮的μ m计而获得的测量结果，同时测试轮处于恒定的静载荷下。该方法提供了沿着被测试的测试表面的整个长度的侧向力摩擦的数据(和其他数据)，其被应用于能够产生结果的各种计算机化算法，包括(但不限于)滚动平均值、数字和图形表示、摩擦映射以及以各种国家机场监管机构批准的布局格式化的报告。1.3 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.4 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。 另见第节 6 . 1.5 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。======意义和用途====== 4.1 侧向力摩擦的知识是表征路面的附加工具。单独的侧向力摩擦数据在确定铺路材料或修整技术的适用性方面可能具有有限的价值。然而，当与其他物理和化学测试结合使用时，侧向力摩擦可能有助于表征路面表面。 4.2 用本文所述的设备和程序测量的值不一定与通过其他铺装表面摩擦测量方法获得的值一致或直接相关。

1.1 This test method covers the measurement of the side force friction of paved surfaces utilizing a device commonly called a Mu-Meter. 2 1.2 This test method utilizes a measurement obtained by pulling the Mu-Meter, containing two freely rotating test wheels angled to the direction of motion, over a pavement surface at a constant speed while the test wheels are under a constant static load. This method provides data of the side force friction (and other data) along the whole length of the test surface being tested which is applied to a variety of computerized algorithms enabling the production of results, including (but not limited to) rolling averages, numeric and graphical representations, friction mapping, and reports formatted in the layout approved by a wide variety of national airport regulators. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. See also Section 6 . 1.5 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 ====== 4.1 The knowledge of side force friction serves as an additional tool in characterizing pavement surfaces. Side force friction data alone may be of limited value in determining the suitability of paving materials or finishing techniques. However, when used in conjunction with other physical and chemical tests, the side force friction may contribute to characterization of pavement surfaces. 4.2 The values measured with the equipment and procedures stated herein do not necessarily agree or correlate directly with those obtained by other paved surface friction measuring methods.
