Over deze norm
This European Standard specifies the measurement method and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of railbound vehicles operating on rails or other types of fixed track, hereinafter conventionally called ?unit?. This standard 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). The results may be used, for example: - to characterise the exterior noise emitted by trains - to compare the noise emission of various units on a particular track section ? to collect basic source data for trains. The type testing procedures specified in this European Standard are of engineering grade (grade 2, with a precision of ± 2 dB), that is the preferred one for noise declaration purposes, as defined in EN ISO 12001. If test conditions (e.g. : vehicle and/or track conditions, measuring conditions) are relaxed for example as done for trackside 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 (see EN ISO 12001).
