16、10/2008 03:47, Uncontrolled Copy, (c) BSI EN 50500:2008 - 4 - Introduction The intention of this European Standard is to establish a suitable measuring/calculation method for determining the magnetic fields in the space around the equipment mentioned in the scope, to standardize operating conditions
17、 and to fix measuring/calculation distances. It offers a method to demonstrate compliance with the council recommendation 1999/519/EC (see Bibliography) and Directive 2004/40/EC (see Bibliography). 1 Scope The scope of this product-family standard is limited to apparatus, systems and fixed installat
18、ions 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 rai
19、lway 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
20、 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: a) Co
21、uncil 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 persons bearing active implantable medical devices. NOTE 1 Not covered is the risk assessment for persons bea
22、ring active implants in magnetic field generated by electronic and electrical apparatus in the railway environment. Not covered are personal electronic devices (e.g. mobile phones, notebooks, wireless communication systems etc.) of passengers and workers. Not covered are intentional transmitters wit
23、h frequencies higher than 20 kHz. NOTE 2 These apparatus (with a working frequency of 9 kHz or higher) are covered by R measurement of a.c. magnetic field: tri-axial probe with three orthogonal loops, loop with 100 cm area, minimum frequency range 5 Hz to 20 kHz. NOTE For measurements in the railway
24、 environment the magnetic flux density B is the magnitude of a field vector that is equal to the magnetic field H multiplied by the permeability 0. HB= 0 5.2.2 Summation of spatial components Three measurements shall be performed at the same time in three orthogonal planes to obtain the different co
