In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

In an electric railway, the trains have to be supplied via sliding contacts from a supply line, called the catenary or overhead, or a trackside conductor rail, which is installed along the track. Emission and immunity of fixed power supply installations and apparatus This part applies to emission and immunity aspects of EMC for electrical and electronic apparatus and components intended for use in railway fixed ne associated with power supply.

Clause 5 provides information about the EMC management. Other parts of this European Standard may contain specific definitions.

This power is fed along the train by separate conductors; signalling and telecommunication systems along the track and between control centres, fn with the movement of trains; computer installations in control centres, linked via trackside routes; 501211-1 information systems on vehicles, stations and depots; traction within diesel-electric locomotives and multiple units; battery traction vehicles.

The apparatus shall continue to operate as intended after the test.

International Classification for Standards ICS is an international classification system for technical standards. Emission and immunity of the signalling and telecommunications apparatus Railway applications – Electromagnetic compatibility Part 5: Railway overhead systems differ from most high voltage overhead lines by being closer to the ground, having more insulators and having less natural cleaning 501221-1 the insulators. Emission and immunity of the signalling and telecommunications apparatus This part specifies limits for electromagnetic emission and immunity for signalling and telecommunications apparatus installed within a Railway.


The railway apparatus is assembled into large systems and installations, such as trains and signalling control centres. Compliance with a British Standard cannot confer immunity from legal obligations. Emission of the whole railway system to the outside world This part sets the emission limits from the railway to the outside world at radio frequencies. This auxiliary current may return to the locomotive via the rails and hence have an influence on apparatus on the track.

Track circuits take many forms with some having frequency and time coding to reduce the risk of false energisation. Other requirements and other EC Directives may be applicable to the products falling within 51021-1 scope of this standard.

These converters may be on several coaches in a train 501121-1 the summation of their noise must be considered. Rolling stock – Train and complete vehicle This part specifies the emission and immunity requirements for all types of rolling stock. The traction and auxiliary equipment on the vehicle and the substations shall not generate currents at track circuit frequencies which exceed specified values.


It is designed to cover every economic 5011-1 and virtually every activity of the humankind where technical standards may be used. Electromagnetic compatibility Emission of the whole railway system to the outside world BS EN If, as a result of the application of the tests defined in this set of standards, the apparatus becomes dangerous or unsafe, the apparatus shall be deemed to have failed the test.

The apparatus shall continue to operate as intended during and after the test. Railway applications – Electromagnetic compatibility – Part 1: On low voltage lines, a trackside conductor rail may be provided from which power is collected by a sliding contact known as the collector shoe.

Give feedback about the content of this standard. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions and the induction effects of direct lightning strike. Annex A describes the characteristics of the railway system which affect electromagnetic compatibility EMC behaviour.

It presents the UK view on standards in Europe and at the international level. Connection points, known as sub-stations, perform the following functions: This prevents the passage of currents at track circuit frequencies in the running rails.
