The resolution of this is a matter for discussion between the equipment supplier and the project manager, infrastructure controller or equivalent. Special conditions may have to be applied for railway equipment which has to work near such a transmitter and these will be accepted as National Conditions for the specification. The biological effects 50112-1 non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.

These effects are local and attenuate rapidly with distance; partial flashovers across dry bands of polluted insulator surfaces. Shopping Cart Your shopping cart is empty. Among the 50112-1 which are involved in RF emission are: Emission and immunity of the signalling and telecommunications apparatus Railway applications – Electromagnetic compatibility Part 5: Take the smart route to manage medical device compliance.
