本推荐规程描述了与实验室测量全系列乘用车轮胎的轮胎力和力矩特性的设备相关的一些基本设计要求和操作程序。必须了解这些特性，以确定轮胎对车辆动态性能的贡献。影响实验室轮胎力和力矩测量的因素很多。本推荐规程是作为设备设计和试验操作指南编制的，以便直接比较来自不同实验室的数据，并将其应用于车辆设计和轮胎选择问题。本推荐规程基于多个实验室用于常规轮胎评估的设备和程序类型。这将本推荐规程的范围限制在测量自由基稳态特性的设备和方法上- 滚动轮胎。这些程序旨在描述轮胎在工作条件下的性能，这些工作条件基本上随时间不变，或者变化足够缓慢，以至于动态影响可以忽略不计（准静态滚动条件）。本推荐规程包括对空间、测量系统范围和精度的具体建议，以测量全系列乘用车轮胎的力和力矩特性。必须强调的是，本推荐规程所依据的经验主要是通过测试乘用车轮胎获得的。

This recommended practice describes some basic design requirements and operational procedures associated with equipment for laboratory measurement of tire force and moment properties of the full range of passenger car tires. These properties must be known to establish the tire's contribution to vehicle dynamic performance. Many factors influence laboratory tire force and moment measurements. This recommended practice was compiled as a guide for equipment design and test operation so that data from different laboratories can be directly compared and applied to vehicle design and tire selection problems. This recommended practice is based on types of equipment and procedures that are used in several laboratories for routine tire evaluation. This limits the scope of this recommended practice to equipment and methodology for measuring the steady state properties of free-rolling tires. The procedures are intended to characterize the performance of the tire under operating conditions which are essentially invariant with time or which vary slowly enough so that dynamic effects are negligible (quasi-static rolling conditions). This recommended practice includes specific recommendations for space, measuring system ranges and accuracy needed to measure the force and moment properties of the full range of passenger car tires. It must be emphasized that the experience on which this Recommended Practice is based has been primarily obtained through testing of passenger car tires.
