标准范围

本文件规定了在湿铺路面上用于乘用车的新轮胎在负载条件下相对于基准的湿抓地力制动性能指数的测量方法。开发的方法旨在减少可变性。为了限制试验程序的可变性，有必要使用参考轮胎。本文件适用于所有乘用车轮胎，但以下轮胎除外:-？标有“ET”的专用轮胎；-？T型临时备用轮胎；-？装有附加装置以提高牵引性能的轮胎（例如，带螺栓的轮胎）。

This document specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on passenger cars on a wet-paved surface.The methods developed are meant to reduce variability. The use of a reference tyre is necessary to limit the variability of the testing procedures.This document applies to all passenger car tyres except for:—    special-use tyres marked with "ET";—    T-type temporary spare tyres;—    tyres fitted with additional devices to improve traction properties (e.g. studded tyres).
