Railway applications - Electromagnetic compatibility - Part 3-2: Rolling stock - Apparatus
This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. EN 50121 3 2 applies for the integration of apparatus on rolling stock.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.
The application of tests shall depend on the particular apparatus, its configuration, its ports, its technology and its operating conditions.
This standard takes into account the internal environment of the railway rolling stock and the external environment of the railway, and interference to the apparatus from equipment such as hand-held radio-transmitters.
If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. transponder systems), then the radiated emission requirement in this standard are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU.
Immunity limits do not apply in the exclusion bands as defined in the corresponding EMC related standard for radio equipment.
This standard does not apply to transient emissions when starting or stopping the apparatus.
The objective of this standard is to define limits and test methods for electromagnetic emissions and immunity test requirements in relation to conducted and radiated disturbances.
These limits and tests represent essential electromagnetic compatibility requirements.
Emission requirements have been selected so as to ensure that disturbances generated by the apparatus operated normally on railway rolling stock do not exceed a level which could prevent other apparatus from operating as intended. The emission limits given in this standard take precedence over emission requirements for individual apparatus onboard the rolling stock given in other standards.
Likewise, the immunity requirements have been selected so as to ensure an adequate level of immunity for rolling stock apparatus.
The levels do not however cover all cases which may occur with an extremely low probability of occurrence in any location. Specific requirements which deviate from this standard shall be specified.
Test requirements are specified for each port considered.
These specific provisions are to be used in conjunction with the general provisions in EN 50121 1.
Bahnanwendungen - Elektromagnetische Verträglichkeit - Teil 3-2: Bahnfahrzeuge - Geräte
Diese Europäische Norm legt Anforderungen zur EMV – Störaussendung und Störfestigkeit – für elektrische und elektronische Geräte fest, die zur Verwendung an Bord von Bahnfahrzeugen vorgese¬hen sind. Sie gilt für den Einbau von Geräten in Bahnfahrzeuge.
Der betrachtete Frequenzbereich reicht von 0 Hz bis 400 GHz. Für Frequenzen, für die keine Anforde-rungen festgelegt sind, brauchen keine Messungen durchgeführt zu werden.
Die Anwendung von Prüfungen muss von dem betreffenden Gerät, seiner Anordnung, seinen Anschlüssen, seiner Technologie und seinen Betriebsbedingungen abhängig gemacht werden.
Diese Norm berücksichtigt die internen Umgebungsbedingungen in Bahnfahrzeugen und die äußere Bahnumgebung sowie Störeinflüsse auf Geräte durch Ausrüstungen wie z. B. Handsprechfunkgeräte.
Wenn ein Anschluss dafür vorgesehen ist, Sende- oder Empfangsfunktionen für den Zweck der Funk-kommunikation auszuführen (Sendefunkgeräte, z. B. Transponder-Systeme), sind die Anforderungen dieser Norm an die gestrahlte Störaussendung nicht dafür vorgesehen, auf die Funkkommunikation eines Sende¬funkgerätes, wie sie von der ITU definiert ist, Anwendung zu finden.
Die Grenzwerte der Störfestigkeit gelten nicht in den ausgenommenen Frequenzbereichen (Ausschluss-bändern), wie in den korrespondierenden auf die EMV bezogenen Normen für Funkgeräte beschrieben.
Diese Norm gilt nicht für die kurzzeitige bzw. impulsförmige Störaussendungen (Transiente) beim Ein- oder Ausschalten des Geräts.
Zweck dieser Norm ist die Festlegung von Grenzwerten und Messverfahren für elektromagnetische Stör-aussendungen und von Prüfanforderungen zur Störfestigkeit bezogen auf leitungsgeführte und gestrahlte Störgrößen.
Diese Grenzwerte und Prüfungen stellen wesentliche Anforderungen zur Elektromagnetischen Verträglichkeit dar.
Die Anforderungen zur Störaussendung wurden so ausgewählt, dass die von Geräten, die an Bord von Bahnfahrzeugen bestimmungsgemäß betrieben werden, erzeugten Störgrößen keinen Pegel überschreiten, mit dem andere Geräte (Betriebsmittel, Einrichtungen) daran gehindert werden, wie beabsichtigt zu arbeiten. Die in dieser Norm angegebenen Grenzwerte der Störaussendung haben Vorrang gegenüber Anforderungen der Störaussendung an einzelne Geräte in Bahnfahrzeugen, die in anderen Normen angegeben werden.
Entsprechend wurden die Anforderungen zur Störfestigkeit so ausgewählt, dass für Geräte in Bahn¬fahr-zeugen eine angemessener Störfestigkeitspegel sichergestellt ist.
Die Prüfpegel decken jedoch nicht extreme Fälle ab, die an jedem Betriebsort mit sehr geringer Wahr-scheinlichkeit auftreten können. Besondere Anforderungen, die von dieser Norm abweichen, müssen festgelegt werden.
Prüfanforderungen sind für jeden betrachteten Anschluss festgelegt.
Diese besonderen Festlegungen müssen in Verbindung mit den allgemeinen Festlegungen der EN 50121-1 angewendet werden.
Applications ferroviaires - Compatibilité électromagnétique - Partie 3-2: Matériel roulant - Appareils
La présente Norme Européenne s’applique aux aspects d’émission et d’immunité de CEM des appareils électriques et électroniques destinés à être utilisés à bord du matériel roulant ferroviaire. L'EN 50121 3 2 s’applique pour l’intégration des appareils à bord du matériel roulant.
La plage de fréquences concernée va du courant continu à 400 GHz. Aucune mesure n’est nécessaire aux fréquences pour lesquelles aucune exigence n’est spécifiée.
L’application des essais doit dépendre des appareils eux-mêmes, de leur configuration, de leurs accès, de leur technologie et de leurs conditions de fonctionnement.
La présente Norme prend en compte l’environnement interne du matériel roulant ferroviaire et l'environnement externe du système ferroviaire, ainsi que les perturbations affectant les appareils provenant d'équipements tels que les émetteurs radioélectriques portables.
Si un accès est destiné à émettre ou recevoir des communications radio (émetteurs intentionnels de rayonnement, par exemple, systèmes de balise), alors les exigences relatives aux émissions rayonnées de la présente Norme ne s'appliquent pas à la transmission intentionnelle à partir d'un émetteur radio tel que défini par l'UIT.
Les limites d'immunité ne s'appliquent pas dans les bandes d'exclusion telles que définies dans la norme CEM correspondante pour les équipements radio.
La présente Norme ne s’applique pas aux émissions de transitoires lors du démarrage ou de l'arrêt des appareils.
L’objectif de la présente Norme est de définir les limites et les méthodes d’essai concernant les émissions électromagnétiques et les exigences relatives aux essais d’immunité en matière de perturbations conduites et rayonnées.
Ces limites et ces essais représentent les exigences essentielles de compatibilité électromagnétique.
Les exigences relatives aux émissions ont été choisies pour assurer que les perturbations générées par l’appareil qui fonctionne normalement à bord du matériel roulant ferroviaire ne dépassent pas un niveau qui pourrait empêcher d’autres appareils de fonctionner comme prévu. Les limites d'émission données dans la présente Norme l'emportent sur les exigences relatives aux émissions des appareillages individuels embarqués sur le matériel roulant données dans les autres normes.
De la même manière, les exigences relatives à l'immunité ont été choisies pour assurer un niveau approprié d’immunité pour les appareils du matériel roulant.
Les niveaux ne couvrent cependant pas tous les cas qui peuvent apparaître avec une très faible probabilité en tout emplacement. Les exigences particulières qui s’écartent de la présente Norme doivent être spécifiées.
Les exigences relatives aux essais sont spécifiées pour chaque accès considéré.
Ces dispositions spécifiques doivent être utilisées avec les dispositions générales données dans l'EN 50121 1.

4 Performance criteria
The variety and the diversity of the apparatus within the scope of this standard make it difficult to define
precise criteria for the evaluation of the immunity test results.
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 criteria
A, B, C defined in EN 50121-1:2015.
5 Conditions during testing
It is not always possible to test every function of the apparatus. The tests shall be made at a typical
operating mode considered by the manufacturer to produce the largest emission or maximum
- 7 - EN 50121-3-2:2015
susceptibility to noise as appropriate in the frequency band being investigated consistent with normal
applications. The conditions during testing shall be defined in a test plan (see basic standard of
EN 61000-4-x series).
If the apparatus is part of a system, or can be connected to auxiliary apparatus, then the apparatus
shall be tested while connected to the minimum configuration of auxiliary apparatus necessary to
exercise the ports in accordance e.g. with EN 55022:2010, Clause 8.
The configuration and mode of operation shall be specified in the test plan and the actual conditions,
during the tests, shall be precisely noted in the test report.
If the apparatus has a large number of similar ports or ports with many similar connections, then a
sufficient number shall be selected to simulate actual operating conditions and to ensure that all the
different types of termination are covered (e.g. 20 % of the ports or at least four ports).
The tests shall be carried out within the specified operating range for the apparatus and at its nominal
supply voltage, unless otherwise indicated.
6 Applicability
The measurements in this standard shall be made on the relevant ports of the apparatus.
It may be determined from consideration of the electrical characteristics, the connection and the usage
of a particular apparatus that some of the tests are not applicable (e.g. radiated immunity of induction
motors, transformers). In such cases, the decision not to test has to be recorded in the test plan and
test report.
If not otherwise specified, the EMC tests shall be type tests.
7 Emission tests and limits
The emission tests and limits for apparatus covered by this standard are given on a port by port basis.
Measurements shall be performed in well-defined and reproducible conditions for each type of
disturbance.
The description of the test, the test methods and the test set-up are given in Basic Standards which
are referred to in Tables 1 to 3.
The contents of these Basic Standards are not repeated here, however modifications or additional
information needed for the practical application of the tests are given in this standard.
NOTE The reference to “Basic Standard“ is intended to be limited to those parts of the standard that give the
description of the test, the test methods and the test set-up.

La norme SIST EN 50121-3-2:2015 est une référence essentielle pour l'application de la compatibilité électromagnétique (CEM) dans le domaine des applications ferroviaires, plus précisément en ce qui concerne les matériels roulants. Cette norme couvre à la fois les aspects d'émission et d'immunité des dispositifs électriques et électroniques destinés à l'utilisation sur des trains. L'un des points forts de cette norme est sa portée, qui s'étend des fréquences continues (DC) jusqu'à 400 GHz, illustrant ainsi une grande flexibilité en intégrant divers types de technologie et configurations d'appareillage. La norme stipule que les mesures ne doivent être effectuées qu'aux fréquences où des exigences spécifiques sont définies, ce qui rationalise le processus de vérification de la CEM. La norme prend également en compte les environnements interne et externe des rames ferroviaires ainsi que les interférences potentielles provenant d'équipements tels que les émetteurs-récepteurs portables. Ceci est crucial puisqu'il s'agit d'assurer que le fonctionnement normal des appareils ferroviaires ne soit pas perturbé par des transmissions extérieures. Les exigences d'émission sont soigneusement établies pour garantir que les perturbations générées par les appareils sur le matériel roulant ne dépassent pas un niveau pouvant affecter le fonctionnement d'autres équipements. De plus, les limites d'immunité ont été choisies pour garantir un niveau adéquat d'immunité pour ces appareils, bien que la norme reconnaisse qu'il peut exister des cas très spécifiques qui nécessiteraient des exigences dérogeant à celles prévues. Les méthodes d'essai sont clairement définies pour chaque port, permettant une approche rigoureuse et standardisée pour l’évaluation des impacts électromagnétiques. Ces provisions spécifiques doivent être utilisées en conjonction avec les dispositions générales de la norme EN 50121-1, soulignant l'importance d'une approche cohérente et harmonisée dans le domaine de la CEM pour le matériel roulant ferroviaire. En résumé, la norme SIST EN 50121-3-2:2015 joue un rôle crucial en établissant des limites et des méthodes d'essai pour les exigences de compatibilité électromagnétique, renforçant la sécurité et l'efficacité des systèmes ferroviaires tout en tenant compte des réalités technologiques et environnementales modernes.
SIST EN 50121-3-2:2015 표준은 철도 애플리케이션의 전자기 호환성(EMC)에 관한 중요한 문서로, 특히 철도 차량의 전기 및 전자 장치에 대한 방출 및 내성 측면을 다루고 있습니다. 이 표준은 전력 장치가 철도 차량에 통합될 때의 요구사항을 제시하며, DC에서 400 GHz까지의 주파수 범위에서 적용됩니다. 특정 주파수에서 요구사항이 명시되지 않은 경우 별도의 측정이 필요하지 않습니다. 이 표준의 강점 중 하나는 철도 차량의 내부 환경과 외부 환경을 모두 고려하고 있다는 점입니다. 전자기파에 대한 내성 요구사항은 수신 및 송신을 목적으로 하는 포트에 대해 명확하게 정의되어 있으며, ITU에서 정의한 라디오 송신기에서의 의도적인 전송에 대한 방출 요구사항은 적용되지 않습니다. 이는 표준이 실제 용도에 맞게 조정되어 있음을 나타냅니다. 또한, 이 표준은 전도 및 방사 간섭에 대한 전자기 방출 및 내성 테스트 요구사항의 한계를 정의하고 있으며, 이러한 한계는 전자기 호환성의 필수적 요구 사항을 반영합니다. 방출 요구사항은 철도 차량에서 정상적으로 작동하는 장치에서 발생하는 간섭이 다른 장치의 정상 작동을 저해하지 않도록 보장하도록 선택되었습니다. 이는 철도 차량 보드에서 개별 장치에 대한 다른 표준에 명시된 방출 요구사항보다 우선합니다. 내성 요구사항 역시 철도 차량 장치에 충분한 수준의 내성을 보장하도록 설계되어 있습니다. 그러나 매우 낮은 확률로 발생할 수 있는 모든 사례를 커버하지는 않으며, 이 표준과 다른 특정 요구사항은 명시적으로 규정되어야 합니다. 각 포트에 대한 테스트 요구 사항이 구체적으로 규정되어 있으며, 이는 EN 50121-1의 일반 조항과 함께 사용됩니다. 총체적으로 SIST EN 50121-3-2:2015는 철도 차량의 전기 및 전자 장치에 대한 EMC 요구사항을 종합적으로 다루면서도 실용적인 면에서 매우 신뢰할 수 있는 규범을 제공합니다.
The SIST EN 50121-3-2:2015 standard provides a comprehensive framework for assessing electromagnetic compatibility (EMC) specifically concerning electrical and electronic apparatus intended for use on railway rolling stock. Its scope is precisely defined, addressing both emission and immunity aspects, and encompasses a frequency range from DC to 400 GHz, emphasizing the importance of tailored test applications based on the specific configuration, technology, and operating conditions of the apparatus. One notable strength of this standard is its detailed delineation of emission requirements designed to ensure that disturbances from rolling stock apparatus remain below levels that could disrupt the functionality of other onboard equipment. This prioritization of emission limits demonstrates a proactive approach to safeguarding the overall operational integrity of railway systems. The immunity requirements outlined are similarly robust, aiming to establish a reliable threshold for electromagnetic disturbances. While the limits may not encompass every conceivable scenario-especially those with a very low probability of occurrence-they successfully provide essential guidance for standard operational environments, enabling manufacturers and operators to ensure that their equipment maintains adequate resilience against external interference, including from hand-held radio transmitters. Moreover, the standard recognizes the distinctions needed for intentional radiators, clarifying that certain radiated emission requirements do not apply to equipment specifically designed for radio communication. This nuanced approach reflects an understanding of the complex interactions within the railway environment and further enhances the standard's applicability. Furthermore, the associated test methods are meticulously specified for each port under consideration, ensuring that compliance can be effectively assessed. By integrating these specific provisions with the general guidelines in EN 50121-1, the standard fosters a harmonized approach to EMC across different apparatus types and configurations. Overall, the SIST EN 50121-3-2:2015 standard is not only relevant but also essential for manufacturers and operators within the railway sector, providing a clear and effective mechanism to manage electromagnetic compatibility challenges faced by rolling stock. Its comprehensive framework underscores its significance in promoting safe and efficient railway operations.

Die SIST EN 50121-3-2:2015 ist ein bedeutendes Dokument, das die elektrotechnische Kompatibilität (EMC) von elektrischen und elektronischen Apparaten im Schienenfahrzeugbereich regelt. Diese europäische Norm fokussiert sich auf die Emissions- und Immunitätsaspekte für Geräte, die in Schienenfahrzeugen eingesetzt werden. Die Norm definiert klare Rahmenbedingungen für die Integration dieser Apparate und berücksichtigt dabei sowohl die interne Umgebung der Bahnfahrzeuge als auch externe Störungen aus der Bahninfrastruktur. Ein zentraler Stärke der Norm ist der umfassende Frequenzbereich von Gleichstrom (DC) bis 400 GHz, der abgedeckt wird. Diese Abdeckung stellt sicher, dass relevante Tests bezüglich der elektromagnetischen Störungen auf einem breiten Spektrum von Frequenzen durchgeführt werden können, jedoch keine Messungen erforderlich sind, wenn für bestimmte Frequenzen keine Anforderungen spezifiziert sind. Diese Flexibilität kann erheblich zur Effizienz der Testverfahren und zur Einhaltung der gesetzlichen Vorgaben beitragen. Darüber hinaus werden spezifische Anforderungen für verschiedene Ports der Apparate festgelegt, was einen gezielten Ansatz bei der Durchführung der Tests ermöglicht. Diese Tests sind wesentlich, um sicherzustellen, dass die elektromagnetischen Störungen, die von den Apparaten erzeugt werden, innerhalb akzeptabler Grenzen bleiben und somit die einwandfreie Funktion anderer Geräte nicht beeinträchtigen. Insbesondere die Emissionsgrenzen in dieser Norm haben Vorrang vor Vorgaben anderer Standards, die für Einzelgeräte an Bord von Schienenfahrzeugen gelten, was die Relevanz der SIST EN 50121-3-2:2015 weiter unterstreicht. Ein weiterer positiver Aspekt ist, dass die Norm auch Immunitätsanforderungen umfasst, um sicherzustellen, dass die Geräte in Schienenfahrzeugen gegen externe Störungen geschützt sind. Jedoch bietet die Norm keine umfassenden Lösungen für sehr unwahrscheinliche Störfälle, was bei der Anwendung der Norm eine gewisse Vorsicht erfordert. Zusätzliche spezifische Anforderungen müssen in solchen seltenen Fällen klar definiert werden. Insgesamt stellt die SIST EN 50121-3-2:2015 wichtige Anforderungen und Testmethoden für die elektromagnetische Verträglichkeit sicher, die für die Integrität und Sicherheit von elektrischen und elektronischen Apparaten auf Schienenfahrzeugen von zentraler Bedeutung sind. Die Norm verbindet technische Präzision mit einer praktischen Anwendbarkeit, was sie zu einem unverzichtbaren Referenzdokument in der Branche macht.
