BS EN 50500:2008+A1:2015

This standard BS EN 50500:2008+A1:2015 Measurement procedures of magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure is classified in these ICS categories:

• 17.240 Radiation measurements

The scope of this product-family standard is limited to apparatus, systems and fixed installations which are intended for use in the railway environment. The frequency range covered is 0 Hz to 300 GHz.

Technical considerations and measurements are necessary for frequencies up to 20 kHz because no relevant field strengths are expected above due to the physical nature of EMF-sources in the railway environment.

The object of this standard is to provide measurement and calculation procedures of electric and magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure.

The regulations regarding the protection of human being during exposure to non-ionizing electromagnetic fields in the railway environment are different within the countries of European Community. This standard offers a procedure regarding measurement, simulation and evaluation.

At present two European documents regarding EMF have to be considered:

1. Council Recommendation 1999/519/EC of 12 July 1999 (see Bibliography);

2. Directive 2013/35/EU (see Bibliography).

The measurement procedures and points of measurement cover also the aspect of persons bearing active implantable medical devices.

Not covered are personal electronic devices (e.g. mobile phones, notebooks, wireless communication systems etc.) of passengers and workers.

Not covered are intentional transmitters with frequencies higher than 20 kHz.
