This collection is via a series of short arcs which act as radio sources; special case arcing and transients which are produced when the pantograph is raised or lowered, or the vehicle circuit breaker is closed or opened. 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.

Electromagnetic compatibility – Requirements and tests You may be interested in this related standard Medical electrical equipment – Part 1. Details are given in annex A. Clause 5 provides information about the EMC management. Connection points, known as sub-stations, perform the following functions: Various BSI electronic information services are also available which give details on all its products and services.

Worldwide Standards We can source any standard from anywhere in the world. Find Similar Items This product falls into the following categories.

Compliance with this standard provides one means of conformity with the specified essential requirements of the Directive concerned. Take the smart route to 5012-11 medical device compliance. It defines the applied test methods and gives information on typical field strength values at traction and radio frequency cartography.

Based on the General data protection regulation, cookies are regarded as personal data. 550121-1 traction and auxiliary equipment on the vehicle and the substations shall not generate currents at track circuit frequencies which exceed specified values. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions e.

It is not, therefore, possible to establish immunity tests and limits for these large assemblies. A management process to achieve EMC at the interface between the railway infrastructure and trains is referenced.

Revisions British Standards are updated by amendment or revision. Limits are applied for particular cases.

Apparatus BS EN This European standard outlines the structure and the content of the whole set. The immunity and emission levels do not of themselves guarantee that the railway will have satisfactory compliance with its neighbours.

EN and EN are product family standards which take precedence over generic standards. Valid Estimated date of Estonian translation publication: A functional description and a definition of performance criteria, during or as a consequence of the EMC testing, shall be provided by the manufacturer and noted in the test report, based on the following criteria: When a train travels on the track, its axles short-circuit a detector of this electrical supply and the presence of the train is detected.

Railway applications – Electromagnetic compatibility – Part 1: It specifies the performance criteria applicable to the whole standards series. Skip to main content. Emission and immunity of the signalling and 501211-1 apparatus.

Safety considerations are not covered by this set of standards. The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.

The current generally returns to the substation via the rails, a separate return conductor or via the earth. 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.

Customers who bought this product also bought BS EN Electromagnetic compatibility Emission and immunity of the signalling and telecommunications apparatus BS EN In all these cases, compatibility must be achieved with consultation and co-operation between the interested parties.

The normal and disturbed working of these systems may be a source of electromagnetic noise which can affect all other systems. Standards are also available from the BSI website at http: Emission of the whole railway system to the outside world Railway applications – Electromagnetic compatibility Part Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.


It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. This publication does not purport to include all the necessary provisions of a contract.

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. Information regarding online access to British Standards via British Standards Online can be found at http: Five modes of coupling are distinguished: 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.

No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. Moreover, the high level of service quality proven by BELAC accreditation in this field makes our laboratories especially attractive for this industry.

Auxiliary power is also 50121–1 and, although of lower power than 50112-1 supplied to the electric traction motors, can still 5121-1 a significant source of electromagnetic noise.
