1.1 本指南描述了被称为连续摩擦测量设备（CFMEs）的摩擦测量系统的评估和校准。使用专用设备、仪器、路面、经过培训的人员和批准的设施，使用以下程序执行评估和校准过程。 1.2 本指南旨在识别和量化影响系统性能的变量，将这些变量的影响降至最低，并提供将CFME与参考防滑测量系统联系起来的方法。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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。 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》中确立的国际公认标准化原则制定的。

1.1 This guide describes the evaluation and calibration of friction measurement systems which are known as Continuous Friction Measuring Equipment (CFMEs). The evaluation and calibration processes, using the specialized equipment, instruments, pavement surfaces, trained personnel, and approved facilities, are performed using the procedures described below. 1.2 This guide is offered as a process to identify and quantify the variables that affect system performance, to minimize the effect of these variables, and to provide a means to relate CFMEs to reference skid measurement systems. 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. 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.
