Describes a type test method to measure noise levels inside the driver's cabs of railway vehicles for assessing compliance with the relevant European legislation.

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.
