轻型汽车干式停车距离

[中文适用范围]： 本文件建立了测量直线行驶路径中干燥或湿沥青上车辆停车距离的最佳实践，旨在由制造商和媒体组织发布配备原装轮胎的车辆的停车距离。建议所有 GVWR 小于 4536 千克（10000 磅）的车辆采用其中的测试方法。该程序通常用于 100 km/h 和 60 mph@ 的初始速度，但也可以使用其他速度。由于轮胎在停车距离@中发挥着重要作用，因此该程序涵盖通常用作新车原始设备的轮胎类型，包括全季节@夏季@和全地形轮胎。本文件可作为所有轮胎类型@的程序指南，但本程序中的表面温度修正公式是使用全季节轮胎开发的，可能不适用于其他轮胎类型。目的 本车辆停车距离程序概述了使用最佳实践在测试设施或测试场地@提供一致结果的方法，包括测试设备标准@车辆和轮胎指南准备@以及干沥青表面摩擦补偿。 [外文原描述]： This document establishes best practices to measure vehicle stopping distance on dry or wet asphalt in a straight path of travel intended for the purpose of publishing stopping distance by manufacturers and media organizations for vehicles with original equipment tires. It is recommended that the test method within be adopted for all vehicles less than 4536 kg (10000 pounds) GVWR. This procedure is typically used with initial speeds of 100 km/h and 60 mph, but other speeds may be used. Since tires play a significant role in stopping distance, this procedure covers tire types typically used as original equipment on new vehicles including all-season, summer, and all-terrain tires. This document may serve as a procedural guideline for all tire types, but the surface temperature correction formulas in this procedure were developed using all-season tires and may not be applicable to other tire types.Cross Reference: ASTM E 445,ASTM F 2493,ASTME1136,ASTME1137,FMVSS105,FMVSS135,ISO 21994,J299
