適用范圍：The scope of this product-family standard is limited to apparatus, systems and fixedinstallations which are intended for use in the railway environment. The frequency rangecovered is 0 Hz to 300 GHz.Technical considerations and measurements are necessary for frequencies up to 20 kHzbecause no relevant field strengths are expected above due to the physical nature ofEMF-sources in the railway environment.The object of this standard is to provide measurement and calculation procedures of electricand magnetic field levels generated by electronic and electrical apparatus in the railwayenvironment with respect to human exposure.The regulations regarding the protection of human being during exposure to non-ionizingelectromagnetic fields in the railway environment are different within the countries ofEuropean Community. This standard offers a procedure regarding measurement, simulationand evaluation.At present two European documents regarding EMF have to be considered:a) Council Recommendation 1999/519/EC of 12 July 1999 (see Bibliography);b) Directive 2004/40/EC (see Bibliography).The measurement procedures and points of measurement cover also the aspect of personsbearing active implantable medical devices.NOTE 1 Not covered is the risk assessment for persons bearing active implants in magnetic field generated byelectronic and electrical apparatus in the railway environment.Not covered are personal electronic devices (e.g. mobile phones, notebooks, wirelesscommunication systems etc.) of passengers and workers.Not covered are intentional transmitters with frequencies higher than 20 kHz.NOTE 2 These apparatus (with a working frequency of 9 kHz or higher) are covered by R&TTE Directive andhave to comply also with LVD (Low Voltage Directive). In this view these apparatus have also limitation of EMfields or a “safety-distance” for these apparatus must be given.
