(Main)Railway applications - Electronic equipment used on rolling stock
Railway applications - Electronic equipment used on rolling stock
This standard applies to all electronic equipment for control, regulation, protection, supply, etc., installed on rail vehicles and associated with: - either the accumulator battery of the vehicle; - or a low voltage power supply source with or without a direct connection to the contact system (transformer, potentiometer device, auxiliary supply); with the exception of electronic power circuits, which conform to EN 50207. This standard covers the conditions of operation, design, construction, and testing of electronic equipment, as well as basic hardware and software requirements considered necessary for competent, reliable equipment. Additional requirements in other standards or individual specifications may complement this standard, if they are justified. Specific requirements related to practices necessary to assure defined levels of functional safety are to be determined in accordance with 4.6.3.1 and 4.6.3.2 of EN 50126 and its informative Annex A. Software safety integrity level of 1 or higher shall only be considered when it is shown that a residual safety risk remains and that it has to be carried by the software driven programmable electronic system. In such a case (i.e. software safety integrity level 1 or higher), EN 50128 is applicable. For the purpose of this standard, electronic equipment is defined as equipment mainly composed of semiconductor devices and recognized associated components. These components will mainly be mounted on printed boards. NOTE Sensors (current, voltage, speed, etc.) and firing unit printed board assemblies for power electronic devices are covered by this standard. Complete firing units are covered by EN 50207.
Bahnanwendungen - Elektronische Einrichtungen auf Schienenfahrzeugen
Diese Norm gilt für alle elektronischen Einrichtungen für die Steuerung, die Regelung, den Schutz, die Ver-sorgung usw., die auf Schienenfahrzeugen installiert sind und verbunden sind mit: – entweder der Akkumulatorenbatterie des Fahrzeuges oder – einer Niederspannungsstromversorgung mit oder ohne direkten Anschluss an die Netzspannung (Trans-formator, Spannungsteiler, Hilfsstromversorgung) mit Ausnahme der elektronischen Starkstromkreise, die EN 50207 entsprechen. Diese Norm enthält die Betriebsbedingungen, die Bemessung, den Aufbau und die Prüfung der elektro¬ni-schen Einrichtungen ebenso wie die grundlegenden Hardware- und Softwareanforderungen, die für eine leistungsfähige, zuverlässige Einrichtung als erforderlich erachtet werden. Zusätzliche Anforderungen in anderen Normen oder Einzelbestimmungen dürfen diese Norm ergänzen, wenn sie gerechtfertigt sind. Besondere Anforderungen bezüglich Maßnahmen zur Gewährleistung der funktionellen Sicherheit sind fest-zulegen nach 4.6.3.1 und 4.6.3.2 von EN 50126 und ihrem informativen Anhang A. Software-Safety Integrity-Level 1 oder höher darf nur betrachtet werden, wenn nachgewiesen ist, dass ein Restsicherheitsrisiko verbleibt und dass es durch das softwarebetriebene programmierbare elektronische System abgedeckt ist. In diesem Fall (d. h. Software-Safety Integrity-Level 1 oder höher) ist EN 50128 an¬wendbar. Elektronische Einrichtung im Sinne dieser Norm wird definiert als eine Einrichtung, die hauptsächlich aus Halbleiterbauteilen und üblicherweise zugehörigen Bauelementen aufgebaut ist. Diese Bauelemente werden hauptsächlich auf Leiterplatten montiert. ANMERKUNG Sensoren (Strom, Spannung, Geschwindigkeit usw.) und bestückte Leiterplatten in Zündeinheiten für Bau¬elemente der Leistungselektronik sind in dieser Norm enthalten. Vollständige Zündeinheiten sind in EN 50207 ent-halten.
Applications ferroviaires - Equipements électroniques utilisés sur le matériel roulant
La présente norme s'applique à tous les équipements électroniques de commande, de régulation, de protection, d'alimentation, etc., montés sur des véhicules ferroviaires et reliés - soit à la batterie d'accumulateurs du véhicule; - ou une source d’alimentation basse tension avec ou sans un raccordement direct au système de contact (transformateur, potentiomètre, alimentation auxiliaire) A l’exception des circuits d’électronique de puissance, qui sont conformes à l’EN 50207. Cette norme couvre les conditions de fonctionnement, la conception, la construction mécanique et les essais des équipements électroniques ainsi que les exigences de base du matériel et logiciel considérées comme nécessaires pour des équipements aptes à fonctionner et fiables. Des exigences additionnelles contenues dans d'autres normes ou dans des spécifications particulières peuvent compléter cette norme, si elles sont justifiées. Les exigences spécifiques relatives aux pratiques nécessaires pour assurer des niveaux définis de sécurité fonctionnelle doivent être déterminées conformément aux 4.6.3.1 et 4.6.3.2 de l’EN 50126 et à son Annexe informative A. Les niveaux d’intégrité de la sécurité logicielle supérieurs ou égaux à 1 doivent être considérés uniquement quand il est montré qu’un risque sécuritaire résiduel demeure et qu’il doit être supporté par le système électronique programmable piloté par logiciel. Dans un tel cas (c.-à.-d. niveau d’intégrité de la sécurité logicielle supérieur ou égal à 1), l’EN 50128 est applicable. Pour les besoins de cette norme, un équipement électronique est défini comme étant un équipement composé principalement de composants semi-conducteurs et des composants qui y sont associés. Ces composants sont généralement montés sur carte à circuit imprimé. NOTE Les capteurs (de courant, tension, vitesse, etc.) et les cartes imprimées équipées des allumeurs des composants de puissance sont couverts par cette norme. Les allumeurs complets sont couverts par l'EN 50207.
Železniške naprave – Elektronska oprema na voznih sredstvih
Ta standard se uporablja za vso elektronsko opremo za nadzor, regulacijo, zaščito, napajanje itd., ki je nameščena na železniška vozila in povezana z akumulatorsko baterijo vozila ali nizkonapetostnim napajalnim virom z neposredno povezavo do kontaktnega sistema (transformator, potenciometer, pomožno napajanje) ali brez nje, razen za elektronske tokokroge, ki so skladni s standardom EN 50207. Ta standard zajema pogoje obratovanja, načrtovanja, gradnje in preskušanja elektronske opreme ter osnovne zahteve glede strojne in programske opreme, ki se obravnavajo kot nujne za zmogljivo in zanesljivo opremo. Če so utemeljene, lahko dodatne zahteve iz drugih standardov ali posamezne specifikacije dopolnjujejo ta standard. Posebne zahteve v zvezi s praksami, ki so potrebne za zagotovitev opredeljenih ravni funkcionalne varnosti, je treba določiti v skladu s točkama 4.6.3.1 in 4.6.3.2 standarda EN 50126 ter njegovim informativnim dodatkom A. Stopnja 1 varnostne celovitosti programske opreme ali višja stopnja se upošteva le, kadar se dokaže, da je še vedno prisotno preostalo varnostno tveganje in da je obvezna za programabilne elektronske sisteme na podlagi programske opreme. V takem primeru (tj. pri stopnji 1 varnostne celovitosti programske opreme ali višji stopnji) se uporablja standard EN 50128. V tem standardu je elektronska oprema definirana kot oprema, sestavljena predvsem iz polprevodniških naprav in priznanih pripadajočih sestavnih delov. Ti sestavni deli se bodo namestili predvsem na tiskana vezja.
