ISO 3095:2013规定了测量方法和条件，以获得在轨道或其他类型的固定轨道上运行的所有类型的车辆（下文中通常称为“单元”）的可再现和可比较的外部噪声发射水平和频谱。 ISO 3095:2013适用于装置的型式试验。它不包括描述其他基础设施相关源（桥梁、交叉口、开关、冲击噪声、弯曲噪声等）噪声排放的所有说明。）. ISO 3095:2013不适用于: -轨道维修单位工作时的噪音排放； -环境影响评估； -噪音排放评估； -引导巴士； -警告信号噪声。 例如，可以使用结果: -表征单元发出的外部噪声； -比较特定轨道区段上的各种单元的噪声发射； -收集单位的基本源数据。

ISO 3095:2013 specifies measurement methods and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called "unit". ISO 3095:2013 is applicable to type testing of units. It does not include all the instructions to characterize the noise emission of the other infrastructure related sources (bridges, crossings, switching, impact noise, curving noise, etc.).

ISO 3095:2013 is not applicable to: - the noise emission of track maintenance units while working; - environmental impact assessment; - noise emmission assessment; - guided buses; - warning signal noise. The results may be used, for example: - to characterize the exterior noise emitted by units; - to compare the noise emission of various units on a particular track section; - to collect basic source data for units.
