The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here. Low frequency noise can be significant within a wide zone, up to 3 km or more if the ground resistivity is high.

Railway applications – Electromagnetic compatibility – Part 1: General
Moreover, the high level of service quality proven by BELAC accreditation in this field makes our laboratories especially attractive for this industry. Standards are also available from the BSI website at http: These include neighbouring railway systems; trackside radio stations e.
These effects are entirely internal to the railway and many different cases can exist. Valid Estimated date of Estonian translation publication: The power obtained by this means is transmitted to the traction vehicle via a system of flexiblesuspension contact lines known as the overhead catenary with which a locomotive-mounted articulated device known as the pantograph is brought into contact.
Rolling stock – Train and complete vehicle Railway applications – Electromagnetic compatibility Part In all these cases, compatibility must be achieved with consultation and co-operation between the interested parties. 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: It is produced transiently at substations when high voltage switching takes place, is distributed along the overhead when it is energised, is enhanced when non-linear traction loads such as rectifiers are supplied, and is stimulated locally when flashover takes place.
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.
Clause 5 provides information about the EMC management. Information regarding online access to British Standards via British Standards Online can be found at http: Electromagnetic compatibility Rolling stock.
This creates an interface between these two entities. 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. Rolling stock – Apparatus This part applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. Electrical noise may energise the detector although the train is present, giving a false indication of clear track.
It is incorporated by Royal Charter. Since the power supply may contain voltage components at track circuit frequencies, the input impedance of the train may have to be greater than a specified value. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.
Based on the General data protection regulation, cookies are regarded em personal data. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies.
Such locomotives also contain auxiliary systems which may be sources. We recommend that you check the website of the publishers of the international document before making a purchase. Your shopping cart is empty.
The apparatus shall continue to operate as intended after the test. Further information can be found in our privacy statement. 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.
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. General This part gives a description of the electromagnetic behaviour of a railway; it specifies the performance criteria for the whole set.
Annex A describes the characteristics of the railway system which affect electromagnetic compatibility EMC behaviour. These effects are local and attenuate rapidly with distance; partial flashovers across dry bands of polluted insulator surfaces.

It consists of five parts described at the end of this introduction. This current, which can be A, is a source of noise to adjacent equipment.

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. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions e. The normal and disturbed working of these systems may be a source of electromagnetic noise which can affect all other systems. Search all products by. Limits are 501211 for particular cases. No change of actual operating state or stored data is allowed.
Take the smart route to manage medical device compliance. Hence, problems of EMC arise not only within the locomotive and the power supply but also in these associated systems.
