If the minimum 501211 level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation, and from what the user may reasonably expect from the apparatus if used as intended.

This creates an interface between these two entities. This part alone is not sufficient to give presumption of conformity to the essential requirements of the EMC-Directive and must be used in conjunction with other parts of this standard.

Eb specifies the performance criteria applicable to the whole standards series. The compatibility between railway emissions and their external environment is based upon emission limits from the een being set by considering the results from measurements at the time that the EMC Directive became enforceable.

Give feedback about the content of this standard. Track circuits take many forms with some having frequency and time coding to reduce the risk of false energisation. The frequency covered by the standards is in the range from d.

It is also used as a means of dealing with the 50211-1 of immunity testing a complete vehicle.

Temporary loss of function is allowed, provided the function is selfrecoverable or can be restored by the operation of the controls. The Electronic Components EMC department of the ANPI laboratories conducts tests on components installed on trains and along the tracks, in accordance with the following standards. A management process to achieve EMC at the interface between the railway infrastructure and trains is referenced. Although of relatively low power, these elements are close to the line and may affect other railway apparatus.


Such locomotives also contain auxiliary systems which may be sources.

Limits are applied for particular cases. BS EN 1 Non-electrified traction such as diesel electric traction may also be a source of EM noise. The biological effects of non-ionising radiation as well as apparatus for medical assistance, such as pacemakers, are not ne here.

Annex A describes the characteristics of the railway system which affect electromagnetic compatibility EMC behaviour. The railway apparatus is assembled into large systems and installations, such as trains and signalling 501121-1 centres.

Refer to EN for defining the management process to comply with this requirement. These effects are local and attenuate rapidly with distance; partial flashovers across dry bands of polluted insulator surfaces. Various BSI electronic information services are also available which give details on all its products and services.

Other parts of this European Standard may contain specific 550121-1. The immunity levels for the apparatus will normally ensure reliable operation, but it is necessary to prepare an EMC management plan to deal with complex situations or to deal with specific circumstances.

It is incorporated by Royal Charter. The railway is an integrated system in which electricity has many uses in addition to train propulsion including: It is the constant aim of BSI to improve the quality of our products and services.

We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Along with these technical constraints, there is a particular additional requirement in the railway industry: It consists of five parts described at the end of this introduction.

Railways, Electromagnetic fields, Performance, Railway vehicles, Electromagnetic radiation, Noise spurious signalsElectric power transmission lines, Electromagnetic compatibility, Railway electric traction equipment, Electronic equipment and components, Radio disturbances, Railway equipment, Electrical equipment Railway Applications.


Five modes of coupling are distinguished: Emission limits at the railway boundary do not apply to intentional transmitters within the railway boundaries.

Information regarding online access to British Standards via British Standards Online can be found at http: BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. The current generally returns to the substation via the rails, a separate return conductor or via the earth. Railway applications – Electromagnetic compatibility Part 2: Train and complete vehicle.

This European Standard supersedes EN No change of actual operating state or stored data is allowed. Radio frequency radiated waves. High voltage Medium voltage Low voltage: The apparatus shall continue to operate as intended after the test.

General This part gives a description of the electromagnetic behaviour of a railway; it specifies the performance criteria for the whole set. This auxiliary current may return to the locomotive via the rails and hence have an influence on apparatus on the track.
