(Amendment)Railway applications - Electromagnetic compatibility - Part 3-2: Rolling stock - Apparatus
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 is 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 on board 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.

Ta evropski standard se uporablja za vidike sevanja in odpornosti elektromagnetne združljivosti za električne in elektronske naprave, namenjene za uporabo v železniških vozilih. Standard EN 50121-3-2 se uporablja za integracijo naprav v voznih sredstvih.
Obravnavan frekvenčni razpon je od DC do 400 GHz. Za frekvence, za katere ni določenih zahtev, ni treba opraviti meritev.
Uporaba preskusov je odvisna od določenih naprav, njihovih konfiguracij, vrat, tehnologije in obratovalnih pogojev.
Ta standard upošteva notranje okolje železniškega vozila in zunanje okolje železnice ter motnje v napravah zaradi opreme, kot so ročni radijski oddajniki.
Če so vrata namenjena oddajanju ali sprejemanju za radijsko komunikacijo (namenski radiatorji, npr. sistemi transponderjev), se zahteva glede sevanja v tem standardu ne uporablja za namensko oddajanje radijskega oddajnika, kot je opredeljeno v ITU.
Omejitve odpornosti ne veljajo za pasove izključenosti, kakor je opredeljeno v ustreznem standardu glede elektromagnetne združljivosti za radijsko opremo.
Ta standard se ne uporablja za prehodno sevanje pri zagonu ali zaustavitvi naprave.
Cilj tega standarda je opredeliti mejne vrednosti in preskusne metode za zahteve glede elektromagnetnega sevanja in preskusa odpornosti v zvezi z prevodnimi in sevanimi motnjami.
Te mejne vrednosti in preskusi predstavljajo osnovne zahteve elektromagnetne združljivosti.
Zahteve glede sevanja so izbrane tako, da zagotavljajo, da motnje, ki jih proizvedejo naprave pri običajnem delovanju v železniških vozilih, ne presežejo ravni, ki bi lahko drugim napravam preprečila delovanje, za katerega so namenjene. Mejne vrednosti sevanja, podane v tem standardu, imajo prednost pred zahtevami glede sevanja posameznih naprav v voznem sredstvu, ki so podane v drugih standardih.
Prav tako so zahteve glede odpornosti izbrane tako, da zagotavljajo ustrezno raven odpornosti naprav v voznih sredstvih.
Vendar stopnje ne zajemajo vseh primerov, ki se lahko z zelo majhno verjetnostjo zgodijo na kateri koli lokaciji. Določiti je treba posebne zahteve, ki odstopajo od tega standarda.
Preskusne zahteve so določene za vsaka obravnavana vrata.
Te posebne določbe je treba uporabljati v povezavi s splošnimi določbami standarda EN 50121-1.

Overview
EN 50121-3-2:2016/A1:2019 (CENELEC) defines electromagnetic compatibility (EMC) requirements for electrical and electronic apparatus intended for use on railway rolling stock. The standard covers emission and immunity aspects for apparatus integration on trains, addressing conducted and radiated disturbances in the frequency range from DC to 400 GHz. It complements the general provisions of EN 50121-1 and supports conformity with EU Directive 2014/30/EU.
Key Topics and Requirements
- Scope of EMC: Applies to both emission and immunity of apparatus when installed on rolling stock; takes into account internal (onboard) and external (railway environment) interference sources, including handheld radio transmitters.
- Frequency range: Requirements cover DC to 400 GHz; no measurements are required for frequencies where no requirement is specified.
- Emission vs. intentional radiators: If a port is an intentional radio transmitter/receiver (e.g., transponder), the standard’s radiated emission requirement is not intended to apply to the intentional transmission as defined by ITU; immunity limits exclude bands defined by radio-equipment EMC standards.
- Test scope and configuration: Test application depends on the apparatus’ configuration, ports, technology and operating conditions; apparatus must be tested with the minimum auxiliary configuration necessary to exercise ports.
- Exclusions: Transient emissions at apparatus start/stop are not covered.

The SIST EN 50121-3-2:2017/A1:2019 standard addresses critical aspects of electromagnetic compatibility (EMC) specifically for electrical and electronic apparatus used on railway rolling stock. This standard is pivotal in establishing emission and immunity requirements, thereby facilitating the reliable integration of such apparatus on rolling stock. The scope of this standard is comprehensive, covering a wide frequency range from DC up to 400 GHz, and it stipulates that measurements are only required at specific frequencies where EMC requirements are explicitly defined. By considering both the internal environment of rolling stock and external interferences-such as those from handheld radio transmitters-the standard ensures a thorough approach to mitigating potential disruptions. A key strength of the SIST EN 50121-3-2:2017/A1:2019 is its clear delineation of limits and test methods for electromagnetic disturbances. This framework is essential for maintaining the operational integrity of various apparatus aboard the rolling stock. The emission limits specified ensure that any disturbances generated do not interfere with the functionality of adjacent equipment, thereby prioritizing the operational reliability within the entire railway system. The differentiation between intentional radiators and other sources of emission is particularly noteworthy. The standard clarifies that the radiated emission requirements do not apply to intentional transmissions, indicating a nuanced understanding of the different roles radio communication apparatus play within the broader context of railway operations. Moreover, the detailed specification of test requirements for each port adds another layer of precision essential for compliance. While the immunity levels set forth provide an adequate threshold to ensure reliable operation, the standard also acknowledges the potential for rare cases outside of typical operational parameters. This pragmatic approach enhances its relevance, as it allows for specific deviations to be outlined as necessary by stakeholders, thus fostering flexibility in practical applications. In conclusion, the SIST EN 50121-3-2:2017/A1:2019 standard is instrumental in defining essential EMC requirements for railway rolling stock apparatus. It stands out for its thorough scope, well-defined limits, and test methodologies, reinforcing its relevance in promoting safety, reliability, and operational harmony within the railway sector.

Die Norm SIST EN 50121-3-2:2017/A1:2019 behandelt die elektromagnetische Verträglichkeit (EMV) von elektrischen und elektronischen Geräten, die für den Einsatz in Schienenfahrzeugen vorgesehen sind. Sie legt den Anwendungsbereich für Emission und Immunität von Geräten fest, und ist damit besonders relevant für die Integration dieser Apparate auf dem Schienenfahrzeug. Ein herausragendes Merkmal dieser Norm ist die Berücksichtigung eines breiten Frequenzspektrums von DC bis 400 GHz, was sicherstellt, dass sie aktuelle technologische Entwicklungen im Bereich der elektrischen und elektronischen Apparate abdeckt. Die Norm ist darauf ausgelegt, dass keine Messungen erforderlich sind, wenn keine spezifischen Anforderungen bestehen, was den Prüfaufwand erheblich reduziert. Die Norm geht zudem auf verschiedene Umgebungen ein, sowohl auf die interne Umgebung des Schienenfahrzeugs als auch auf externe Störungen durch Geräte wie tragbare Funkgeräte. Dies ist ein entscheidender Vorteil, da er dazu beiträgt, die tatsächlichen Betriebsbedingungen besser zu reflektieren und somit die Relevanz der EMV-Tests zu erhöhen. Ein weiterer Vorteil ist, dass die Norm spezifische Anforderungen für Ports definiert, die für die Funkkommunikation vorgesehen sind, jedoch explizit klarstellt, dass die Anforderungen bezüglich der emittierten Strahlung von Funkübertragungsgeräten nicht auf solche absichtlich strahlenden Geräte anwendbar sind. Dies hilft, Missverständnisse und unnötige Tests zu vermeiden. Die Festlegung von Emissions- und Immunitätsgrenzen stellt sicher, dass die erzeugten Störungen unter einem Niveau bleiben, das die Funktion anderer Geräte auf dem Schienenfahrzeug beeinträchtigen könnte. Dies ist besonders wichtig, da die in der Norm festgelegten Emissionsgrenzen Vorrang vor den Anforderungen für Einzelgeräte genießen, die in anderen Normen festgelegt sind. Die Immunitätsanforderungen gewährleisten ein angemessenes Immunitätsniveau für die Apparate, jedoch müssen spezifische Abweichungen explizit angegeben werden. Die Norm SIST EN 50121-3-2:2017/A1:2019 ist somit ein unverzichtbares Dokument für die Gewährleistung der elektromagnetischen Verträglichkeit im Bereich der Schienenfahrzeuge. Sie bietet klare und umfassende Richtlinien für die Tests und Anforderungen, die notwendig sind, um die ordnungsgemäße Funktionalität und Sicherheit in einem sich ständig weiterentwickelnden technischen Umfeld zu gewährleisten.
SIST EN 50121-3-2:2017/A1:2019 표준은 철도 애플리케이션에 대한 전자기 호환성(EMC) 관련 한계를 정의하고 테스트 방법을 제시하는 문서로, 주로 철도 차량에서 운영되는 전기 및 전자 장비에 적용됩니다. 이 표준의 범위는 직류부터 400GHz까지의 주파수를 포함하며, 특정 장비의 구성, 포트, 기술 및 운영 조건에 따라 테스트 적용이 달라질 수 있습니다. 이 표준의 강점 중 하나는 철도 차량의 내부 환경과 외부 환경을 고려하여 전자기 간섭을 효과적으로 관리할 수 있도록 설계되었다는 점입니다. 또한, 휴대용 무선 송신기와 같은 외부 장비가 제공하는 간섭으로부터 장비를 보호하기 위한 명확한 규정을 가지고 있습니다. 특히, 의도된 송신을 위한 포트는 ITU에 정의된 무선 송신기에서 의도적인 전송으로 인정되지 않기 때문에, 이와 관련된 방사 방출 요구사항이 적용되지 않는 점은 실용적입니다. 표준에서는 장비가 정상적으로 운영될 때 발생하는 간섭이 다른 장비의 적절한 작동을 방해하지 않도록 하기 위해 전자기 방출의 한계를 세심하게 설정하였습니다. 이 방출 한계는 다른 표준에서 규정한 철도 차량 내 개별 장비의 방출 요구사항보다 우선적으로 적용됩니다. 마찬가지로, 철도 차량 장비에 대한 적절한 면역 수준을 확보하기 위해 면역 요구사항도 선정되었습니다. 표준은 각 포트에 대해 특화된 테스트 요구사항을 명시하고 있으며, 일반 조항인 EN 50121-1과 함께 사용되어야 합니다. 이처럼 SIST EN 50121-3-2:2017/A1:2019 표준은 철도 분야의 전자기 호환성 관련 요구사항을 효과적으로 충족시킬 수 있는 핵심적인 문서로써, 철도 차량 장비의 안전하고 안정적인 운영에 기여합니다.
La norme SIST EN 50121-3-2:2017/A1:2019 établit des critères fondamentaux pour l'interopérabilité et la compatibilité électromagnétique des appareils destinés aux matériels roulants ferroviaires.

Le champ d'application de cette norme est bien défini, couvrant une large gamme de fréquences allant de la DC jusqu'à 400 GHz. Cela permet de s'assurer que tous les aspects de CEM sont pris en compte, depuis les conditions de fonctionnement spécifiques des appareils jusqu'à leur intégration dans le matériel roulant. Les exigences en matière d'émission visent à garantir que les perturbations générées par le matériel en service ne nuisent pas à l'exploitation d'autres équipements autour d'eux. Un des points forts de cette norme réside dans son approche systématique concernant les tests d'immunité et d'émission. En définissant des méthodes d'essai précises et des limites clairement énoncées, la norme permet une évaluation cohérente et fiable de la compatibilité électromagnétique des appareils. Les seuils d'immunité ont été soigneusement sélectionnés pour assurer une protection adéquate contre les perturbations potentielles, assurant ainsi le bon fonctionnement des dispositifs dans un environnement ferroviaire complexe. En outre, la norme prend en compte les environnements internes et externes des matériels roulants, tout en spécifiant que certaines exigences d'émission ne s'appliquent pas aux systèmes destinés à la communication radio, comme les émetteurs-récepteurs. Cette distinction est essentielle pour les fabricants et les opérateurs ferroviaires, car elle stipule clairement les situations où des exigences différentes peuvent s'appliquer, renforçant ainsi la pertinence de la norme dans diverses configurations d'équipement. L'application des exigences de la norme SIST EN 50121-3-2:2017/A1:2019, conjuguée aux dispositions générales de la norme EN 50121-1, fait de ce document une référence incontournable pour garantir la conformité et la sécurité des opérations ferroviaires en matière de compatibilité électromagnétique. En conclusion, la norme se révèle être un outil indispensable pour les concepteurs et les fabricants souhaitant s'assurer que leur matériel roulant respecte les exigences de CEM, favorisant ainsi la fiabilité et l'efficacité des systèmes de transport ferroviaire.
