标准范围

ISO/TS 11819-3:2017规定了使用ISO 11819-2中规定的近距离（CPX）方法时用作参考轮胎的两个轮胎。CPX方法是一种在轮胎/道路噪声占主导地位的条件下，评估不同路面对交通噪声影响的方法。该方法理想地要求使用标准化轮胎，该轮胎具有广泛代表路面对乘用车和重型车辆轮胎噪声排放影响的噪声特性。然而，ISO 11819-2中未规定此类轮胎。本文件用于规定这些标准化轮胎。

ISO/TS 11819-3:2017 specifies two tyres intended to serve as reference tyres when using the close-proximity (CPX) method specified in ISO 11819-2.The CPX method is a method for evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. This method ideally requires the use of standardized tyres, which have noise characteristics that are broadly representative of the effect of road surfaces on the noise emission of passenger car and heavy vehicle tyres. However, such tyres are not specified in ISO 11819-2. This document serves to specify these standardized tyres.
