标准范围

本文件规定了温度对受轮胎/道路噪声影响的车辆噪声排放影响的校正程序。考虑的温度是道路和环境空气温度。本文件适用的噪声排放是通过ISO 11819-1或类似方法测量的，如参考文献[3][4]中规定的美国方法SIP和CTIM。它也适用于在没有加速度的情况下进行的其他通过测量，例如在ISO 10844参考面上测试轮胎和车辆时；然而，考虑到轮胎/道路噪音占主导地位。使用本文件中规定的校正程序，将在某一温度（可能在很大范围内变化）下获得的测量结果归一化为指定的参考温度（20°C）。

This document specifies correction procedures for the effect of temperature on vehicle noise emission, as influenced by the tyre/road noise contribution. Temperatures considered are road and ambient air temperatures.The noise emission for which this document is applicable is measured by means of ISO 11819-1, or similar methods such as the American methods SIP and CTIM specified in References [3][4]. It is also applicable to other pass-by measurements conducted without acceleration, such as when testing tyres and vehicles on test tracks with ISO 10844^[1] reference surfaces; however, given that tyre/road noise is dominant.Measurement results obtained at a certain temperature, which may vary over a wide range, are normalized to a designated reference temperature (20 °C) using a correction procedure specified in this document.
