本SAE推荐规程定义了系统和部件功能、测量指标、用于评估轮胎压力系统功能和性能的测试方法，以及已知操作环境下的推荐维护规程。 本文件适用于车辆额定总重（GVWR）超过7257 kg（16 000 US lb）的单单元动力车辆的全轴和全轮组合，以及最多三（3）个牵引单元的多单元车辆组合，其使用SAE J560连接器进行电源和/或通信，或使用等效的后续连接器技术，或使用合适的容量无线解决方案。 包括的单底盘车辆示例包括:多用途货车和送货车、牵引车、架车、公共汽车、休闲车、燃油车、垃圾车、自卸卡车、水泥车和拖拉机。使用SAE J560或后续连接器的组合车辆示例包括封闭式厢式拖车、液体罐车、平台拖车、记录拖车、自动运输拖车及其相关和兼容的牵引动力装置。对于包括两个或多个拖车的组合车辆，也包括拖车。 包括的车辆可以是新制造的车辆或现有车辆。 建议这些系统解决OEM和/或专业车辆制造商最初安装在车辆上的所有在用轮胎，包括车载备件，对于售后市场（包括更换件或备件），建议（但可选）解决初始车辆销售或使用日期后安装的所有轮胎/轮辋组合。 本文件将重点介绍监测型轮胎压力系统。

This SAE recommended practice defines the system and component functions, measurement metrics, testing methodologies for evaluating the functionality and performance of tire pressure systems, and recommended maintenance practices within the known operating environments. This document is applicable to all axle and all wheel combinations for single unit powered vehicles exceeding 7257 kg (16 000 US lb) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three (3) towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology, or which use a suitable capacity wireless solution. Examples of included single chassis vehicles would be – utility and delivery vans, tow trucks, rack trucks, buses, recreational vehicles, fuel trucks, trash trucks, dump trucks, cement trucks, and tractors. Examples of combination vehicles using an SAE J560 or successor connector would be – enclosed van trailers, liquid tanker, platform trailer, logger trailers, auto transit trailers, and their associated and compatible towing power units. For combination vehicles including two or more trailers, the dollies are also included. The included vehicles can be newly manufactured vehicles or existing vehicles. These systems are recommended to address all tires in service as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, including the vehicle mounted spares, and, for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates. This document will focus on tire pressure systems of the monitoring type.
