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: Find Similar Items This product falls into the following categories.
The railway apparatus is assembled into large systems and installations, such as trains and signalling control centres. Moreover, the high level of service quality proven by BELAC accreditation in this field makes our laboratories especially attractive for this industry. General requirements, tests and guidance for alarm systems in medical electrical equipment and medical electrical systems You may be interested in this related standard.

Temporary loss of function is allowed, provided the function is selfrecoverable or can be restored by the operation of the controls. This plan should be established at as early a stage of the project as is possible.

Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions e. 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. 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 eh breaker is closed or opened. Annex A describes the characteristics of the railway system which affect electromagnetic compatibility EMC behaviour.
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. Emission of the whole railway system to the outside world Railway applications – Electromagnetic compatibility Part These effects are local and attenuate rapidly with distance; partial flashovers across dry bands of polluted insulator surfaces.
Such locomotives also contain auxiliary systems which may be sources.
Other parts of this European Standard may contain specific definitions. Rolling stock – Train and complete vehicle Railway applications – Electromagnetic compatibility Part BS EN It specifies the performance criteria applicable to the whole standards series. Emission 5121-1 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.
Refer to EN for defining the management process to comply with this requirement. Compliance with this standard provides one means of conformity with the specified essential requirements of the Directive concerned.

There may be cases where 5121-1 has to be positioned in restricted spaces or added to an existing assembly, with the possible creation of environments of unusual severity.

These effects are entirely internal to the railway and many different cases can exist. The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.
The biological effects of non-ionising radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.
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 measurements need to be performed at frequencies where no requirement is specified. Users of British Standards should make sure that they possess the latest amendments or editions.
In all these cases, compatibility must be achieved with consultation and co-operation between the interested parties. Isolated three phase lines exist with two overhead conductors. The railway is an integrated system in 5121-1 electricity has many uses in addition to train propulsion including: The normal and disturbed working of these systems may be a source of electromagnetic noise which can affect all other systems.
Train lengths of several hundred metres ej not unusual. Details are given in annex A.
A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as wn official versions. It is not, therefore, possible to establish immunity tests and limits for these large assemblies.
International Classification for Standards ICS is an international classification system for technical standards. Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. 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.
