Railway applications - Noise Emission - Measurement of noise inside driver''s cabs

Asnjë informacion i shtuar.

This European Standard specifies a type test method to measure noise levels inside the driver''s cabs of railway vehicles for assessing compliance with the relevant European legislation. NOTE The relevant European legislation includes Directive 2003/10/EC of 6 February 2003 and the Commission Decisions of 23 December 2005 (Technical specification for interoperability relating to the subsystem ‘rolling stock - noise’ of the trans-European conventional rail system) and of 21 February 2008 (Technical specification for interoperability relating to the ‘rolling stock’ sub-system of the trans-European high-speed rail system). This method is applicable to: - the measurement of noise inside driver''s cab resulting from the sounding of external warning horns when the vehicle is stationary; - the measurement of noise inside the driver cab while the vehicle is running. The method is not applicable to: - complementary measurements that can be requested for acceptance tests, but which are not required by the TSIs referred to in this standard; - the measurement of the noise from internal and external audible devices other than external warning horns; - routine monitoring of the noise exposure of train crew. The test procedures specified in this European Standard are of engineering grade (grade 2) with a precision of ± 2 dB, which is the preferred method for noise declaration purposes, as defined in EN ISO 12001.
