Revisions British Standards are updated by amendment or revision. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. The current generally returns to the substation via the rails, a separate return conductor or via the earth.

This Enn standard outlines the structure and the content of the whole set. Track circuits take many forms with some having frequency and time coding to reduce the risk of false energisation.

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. The variety and the diversity of the apparatus within the scope of this set of standards makes it difficult to define precise criteria for the evaluation of the immunity test results. Customers who bought this product also bought BS EN An overhead line can act as an antenna; auxiliary apparatus on traction vehicles may have relatively high power rating and must be considered as a source of noise; the sliding contact between the line and the pantograph or shoe and rail.

Safety considerations are not covered by this set of standards.

Emission and immunity of fixed power supply eb and apparatus EN EN EN EN EN 2 Normative references The 501211- referenced documents are indispensable for the application of this document. 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.

Give feedback about the content of this standard. Non-electrified traction such as diesel electric traction may also be a source of EM noise. Train lengths of several hundred metres are not unusual. Subscribing members of 501211-1 are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. Hence, problems of EMC arise not only within the locomotive and the power supply but also in these associated systems.

There may be cases where apparatus has to be positioned in restricted spaces or added to an existing assembly, with the possible creation of environments of unusual severity. This auxiliary current may return to the 501211-1 via the rails and hence have an influence on apparatus on the track. For undated references, the latest edition of the referenced document including any amendments applies. Users of British Standards should make sure that they possess the latest amendments or editions.

The set of standards provides both a framework for managing the EMC for railways and also specifies the limits for the electromagnetic EM emission of the railway as wn whole to the outside world and for the EM emission and immunity for equipment operating within the railway. It covers traction stock and trainsets, as well as independent hauled stock.


This power is fed along the train by separate conductors; signalling and telecommunication systems along the track and between control centres, concerned with the movement of trains; computer installations in control centres, linked via trackside routes; passenger information systems on vehicles, stations and depots; traction within diesel-electric locomotives and multiple units; battery traction vehicles.

5012-11 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. 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. Supersedes BS EN The compatibility between railway emissions and their external environment is based upon emission limits from the railways being set by considering the results from measurements at the time that the EMC Directive became enforceable.

International Classification for Standards ICS is an international classification system for technical standards.

On the traction vehicle, the power is regulated and supplied to electric motors to control the movement of the train. The railway eh an integrated system in which electricity has many uses in addition to train propulsion including:
