European Standard EN 50500:2008 defines “Measurement procedures of magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure”.

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

The standard relates to the ICNIRP guidelines. The measurement procedures and points of measurement include consideration of people with active implantable medical devices.

The standard does not include risk assessment for persons bearing active implants in magnetic field generated by electronic and electrical apparatus in the railway environment.

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

Intentional transmitters with frequencies higher than 20 kHz are not covered.
