中文名称：轮胎 滑行法测定轮胎对道路产生的噪音

英文名称：Tyres — Coast-by methods for measurement of tyre-to-road sound emission

标准范围

本文件规定了在滑行条件下，即车辆处于自由滚动、无动力运行时，测量安装在机动车辆上的轮胎对道路声发射的方法。这通常是通过将变速箱置于空档或等效位置，并关闭发动机以及安全驾驶不需要的所有辅助系统来实现的。本文件适用于ISO 3833中定义的乘用车和商用车。本标准不用于确定在动力条件下行驶的车辆轮胎的噪声贡献，也不用于确定给定位置的交通噪声干扰。

This document specifies methods for measuring tyre-to-road sound emissions from tyres fitted on a motor vehicle under coast-by conditions, i.e. when the vehicle is in free-rolling, non-powered operation. This is typically achieved by putting the transmission in the neutral or equivalent position and switching off the engine as well as all auxiliary systems not necessary for safe driving.This document is applicable to passenger cars and commercial vehicles as defined in ISO 3833. It is not intended to be used to determine the sound contribution of tyres of vehicles running in powered condition nor for the determination of traffic sound nuisance at a given location.
