1.1 本标准与设备无关。可通过任何能够为车辆行驶表面产生适当纵向高程剖面的装置进行测量。然而，基于手机的道路评级设备不适用。通常被称为“惯性轮廓仪”的车载轮廓仪被用作一种此类设备的示例。 1.2 高程测量可用于验证或证明剖面设备，或通过将称为候选生产类剖面仪的剖面设备产生的测量值与称为参考类剖面仪（reference Class profiler）的参考剖面设备产生测量值进行比较来确定其对特定应用的适用性。为了进行特定应用的轮廓测量，计算的轮廓应满足本文中针对特定应用或类别规定的精度和重复性要求。适当滤波的选择允许用户获得用于预期应用的合适波长信息。 例如，对于道路粗糙度评估的应用，在使用国际粗糙度指数（IRI）滤波器进行滤波后，使用互相关法确定精度和偏差 ( 1. ) . 2. 1.3 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 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。 第节给出了具体的预防信息 7. . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 对于惯性轮廓仪技术，使用具有波动惯性参考高程的仪表车辆测量车辆行驶表面提供了一种令人满意的获取轮廓高程测量值的方法 ( 1. ) . 5.2 通过模拟，可以处理轮廓数据以产生其他设备的输出。这可以实时完成，也可以作为后处理进行计算。一些可以模拟的设备包括道路仪表 ( 2. ) ，各种直尺装置 ( 3. ) ，轮廓图 ( 4. ) ，以及摊铺机和研磨机。应注意上述模拟设备测量中固有的非线性相移。参考了各种设备及其配置文件计算机程序的比较 ( 5. , 6. ) . 5.3 原始数据或剖面数据也可以稍后记录，用于数据处理和分析，并通过更复杂的数据处理程序进行记录。

1.1 This standard is device independent. Measurements may be made by any device capable of producing a suitable longitudinal elevation profile for the vehicular traveled surface. However, cellular phone-based road rating devices are not applicable. The vehicle-based profiling device, commonly described as the “inertial profiler,” is used as an example of one such device. 1.2 Elevation measurements may be used to validate or certify a profiling device or to determine its suitability for a particular application by comparing measurements produced by a profiling device, called a candidate Production Class profiler, with measurements produced by a reference profiling device, called a Reference Class profiler. To conduct profile measurements for a particular application, the calculated profile shall meet the accuracy and repeatability requirements specified herein for that particular application or class. The selection of proper filtering allows the user to obtain suitable wavelength information for the intended application. For example, for application for road roughness evaluation, the precision and bias are determined using the cross-correlation method after filtering using the International Roughness Index (IRI) filter ( 1 ) . 2 1.3 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. 1.4 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. Specific precautionary information is given in Section 7 . 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 For inertial profiler technology, measuring vehicular traveled surfaces using an instrumented vehicle with a fluctuating inertial reference elevation provides a satisfactory method for acquiring profile elevation measurements ( 1 ) . 5.2 The profile data can be processed to produce, by simulation, the outputs of other devices. This can be done in real time or can be computed as a post-process. Some of the devices that can be simulated include road meters ( 2 ) , various straightedge devices ( 3 ) , profilographs ( 4 ) , as well as pavers and grinders. Caution should be taken regarding the nonlinear phase shifts inherent in the measurements of the above simulated devices. Comparisons of various equipment and their profile computer programs are referenced ( 5 , 6 ) . 5.3 The raw data or the profile data can also be recorded later for data processing and analysis and by more complex data processing procedures.
