本文件规定了测量方法和条件，以获得在轨道或其他类型固定轨道上运行的各类车辆（以下简称“装置”）上的可再现噪声级，但工作模式下的轨道维护车辆除外。 本文件适用于型式试验。它不包括在整个行程中对乘客或驾驶员的噪声暴露进行监测测试或评估的所有说明。 本文件不适用于引导巴士。 它提供了车辆内部噪声的测量程序（通常，车辆型式试验仅使用这些试验中选定的子集进行）: -当车辆以恒定速度行驶时； -当车辆静止时； -当车辆加速或减速时； -当外部警告喇叭鸣响时（欧盟法规应用特别要求）驾驶室内 它不提供以下各项的测量程序: -任何可听信号的可听性或可理解性； -对警告喇叭以外的警告装置进行评估。 由于运行条件，列车乘务员的噪声暴露评估不在本文件的范围内。 可以使用这些结果，例如: -描述这些装置内部的噪声特征； -比较特定轨道区段上不同单元的内部噪声； -收集单元的基本源数据。 本文件中规定的试验程序为工程级（2级），是ISO 12001中规定的用于噪声申报目的的首选等级。如果放宽试验条件，例如，对在役列车进行监测，则结果不再是工程级的。 加速和减速试验规定的程序为调查级（3级）。

This document specifies the measurement method and conditions to obtain reproducible noise levels on-board all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called “unit”, except for track maintenance vehicles in working modes. This document is applicable to type testing. It does not include all the instructions to carry out monitoring testing or evaluation of noise exposure of passengers or drivers over a whole journey. This document is not applicable to guided buses. It provides measurement procedures for vehicle interior noise (in general, a vehicle type test is carried out using only a selected subset of these tests): —    when the vehicle is moving at constant speed; —    when the vehicle is stationary; —    when the vehicle is accelerating or decelerating; —    in the driver's cab when an external warning horn is sounding (specifically required for European Union regulation application) It does not provide measurement procedures for: —    audibility or intelligibility of any audible signals; —    assessment of warning devices other than warning horns. The assessment of noise exposure of train crew due to operational conditions is not in the scope of this document. The results can be used, for example: —    to characterise the noise inside these units; —    to compare the internal noise of various units on a particular track section; —    to collect basic source data for units. The test procedures specified in this document are of engineering grade (grade 2), the preferred grade for noise declaration purposes as defined in ISO 12001. If test conditions are relaxed, for example as they are for monitoring of in-service trains, then the results are no longer of engineering grade. The procedures specified for accelerating and decelerating tests are of survey grade (grade 3).
