SIST EN 50121-3-2:2017/A1:2019
(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.

Železniške naprave - Elektromagnetna združljivost - 3-2. del: Vozna sredstva - Naprave - Dopolnilo A1
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.
- Priority and deviations: Emission limits in EN 50121-3-2 take precedence over other onboard apparatus emission requirements; any specific deviations must be documented.
- Amendment A1 (2019): Updates include modifications to normative references, clarification on testing with auxiliary apparatus, and alignment of Annex ZZ with the European Commission standardisation request supporting Directive 2014/30/EU.
Applications and Users
- Who uses it:
- Rolling stock manufacturers and system integrators
- OEM suppliers of onboard electrical/electronic apparatus
- EMC test laboratories and certification bodies
- Railway operators and procurement/specification writers
- Design and verification engineers for rail electronics
- Practical uses:
- Define EMC test programs for apparatus integration on trains
- Set procurement and acceptance criteria for onboard devices
- Guide design choices to meet immunity and emission performance
- Harmonize EMC assessment during rolling stock certification and safety audits
