1.1 本指南涵盖验证区域参考滑轨测量系统（ARSMS）和相关设备。自1976年以来，这些系统一直用于评估和关联测试方法 1974年/274米 国家交通部主要用作路面管理工具的防滑测量系统。此外，本指南还为ARSMS中更换组件后的重新验证过程提供了指南。 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，并提供一种验证新ARSMS的方法，以取代长期提供质量相关数据的现有ARSMS。 1.3 以英寸磅单位表示的数值将被视为标准，因为ARSMS将与目前所有使用英寸磅单位的州运输系统部门进行比较。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 行驶表面的摩擦特性由防滑测量系统监测，使用这些系统的操作程序为试验方法 1974年/274米 然而，这些系统之间的动态测量差异符合试验方法的要求 1974年/274米 要求这些系统中的每一个与其他系统相关。实现这种相关性的最有效方法是将每个系统与一个单一的、高度精确的系统进行比较，或者在受控环境中与非常有限的系统（两个或三个）进行比较。ARSMS被设计为这样的系统。 图1 描述了防滑测量系统，并显示了主要部件的一般位置。 图1 撬块测量系统 5.2 本指南定义了确保ARSMS继续实现其预期目的的过程。

1.1 This guide covers validating area reference skid measurement systems (ARSMS) and related equipment. These systems have been used since 1976 to evaluate and correlate Test Method E274/E274M skid measurement systems used primarily as a pavement management tool by state Departments of Transportation. Also, this guide provides guidelines for the revalidation process following the replacement of components within an ARSMS. 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 method of validating a new ARSMS to replace an existing ARSMS that has provided quality correlation data for a very long time. 1.3 The values stated in inch-pound units are to be regarded as the standard since the ARSMS will be compared with state departments of transportation systems that all currently use inch-pound units. 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. ====== Significance And Use ====== 5.1 Friction characteristics of traveled surfaces are monitored by skid measurement systems, and the operating procedure for the use of these systems is Test Method E274/E274M . However, dynamic measurement differences between these systems, that comply with the requirements of Test Method E274/E274M , require that each of these systems be correlated to each other system. The most effective approach to accomplish this correlation is to compare each system to a singular, highly accurate system, or to a very limited number (two or three) of systems, in a controlled environment. The ARSMSs were designed to be such systems. Fig. 1 depicts a skid measurement system and shows the general location of the major components. FIG. 1 Skid Measurement System 5.2 This guide defines the process of ensuring that the ARSMSs continue to accomplish their intended purpose.
