标准摘要
[中文适用范围]： 本文件规定了在负载条件下，新商用车轮胎在湿路面使用时，测量其相对湿滑制动性能指数的方法。注：本文件中开发的方法旨在减少测试结果的变异性，使用参考轮胎可限制测试方法的变异性。本文件适用于所有商用车、卡车和客车轮胎。本文件不适用于以下情况：——装有额外装置以提高牵引性能的轮胎（例如钉子轮胎）；——专业越野轮胎。 [外文原描述]： This document specifies the method for measuring the relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on commercial vehicles on a wet-paved surface. NOTE The methods developed in this document are intended to reduce variability. A reference tyre is used to limit the variability of the testing method procedures. This document applies to all commercial vehicle, truck and bus tyres. This document does not apply to: — tyres fitted with additional devices to improve traction properties (e.g. studded tyres); — professional off-road tyres.
英文名称Truck and bus tyres — Method for measuring relative wet grip performance — Loaded new tyres
