Applications ferroviaires - Équipements électroniques utilisés sur le matériel roulant
Le présent projet de Norme européenne s'applique à tous les équipements électroniques de commande, de régulation, de protection, de diagnostic, d'alimentation, etc. montés sur des véhicules ferroviaires.
Pour les besoins du présent projet de Norme européenne, un équipement électronique est défini comme étant un équipement composé principalement de dispositifs à semiconducteurs et des composants qui y sont associés. Ces composants sont généralement montés sur des circuits imprimés.
Les capteurs (de courant, tension, vitesse, etc.) et les circuits imprimés d'allumage des équipements électroniques de puissance sont couverts par la présente Norme. Les allumeurs et circuits de puissance électroniques complets sont couverts par l'EN 61287-1.
Le présent projet de Norme européenne couvre les conditions de fonctionnement, les exigences de conception, la documentation et les essais des équipements électroniques, ainsi que les exigences matérielles et logicielles de base considérées comme nécessaires pour assurer la conformité et la fiabilité des équipements.
Les exigences spécifiques relatives aux pratiques nécessaires pour assurer des niveaux définis de sécurité de fonctionnement sont déterminées conformément aux normes de sécurité ferroviaire correspondantes.
Sous réserve des spécifications de l'alinéa ci-dessus, le logiciel relève du domaine d'application de la présente Norme tant qu'une norme pertinente relative aux logiciels embarqués sur les matériels roulants n'est pas disponible.
NOTE Une norme relative aux logiciels embarqués sur les matériels roulants (à l'exception des logiciels de commande et de protection des trains) est en cours d’élaboration.
Železniške naprave - Vozna sredstva - Elektronska oprema
Ta osnutek evropskega standarda se uporablja za vso elektronsko opremo za nadzor, regulacijo, zaščito, diagnosticiranje napajanje itd., ki je nameščena na železniška vozila.
Za namene tega osnutka evropskega standarda 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.
Ta standard zajema tipala (za tok, napetost, hitrost itd.) in sestave plošč tiskanih vezij sprožilnih enot za močnostne naprave. Celoten seznam sprožilnih enot in močnostnih elektronskih tokokrogov je podan v standardu EN 61287-1.
Ta osnutek evropskega standarda zajema pogoje za obratovanje, zahteve za načrtovanje, dokumentacijo in preskušanje elektronske opreme ter osnovne zahteve glede strojne in programske opreme, ki se obravnavajo kot nujne za skladno in zanesljivo opremo.
Posebne zahteve v zvezi s praksami, ki so potrebne za zagotovitev določenih ravni funkcionalne varnosti, bodo določene v skladu z ustreznimi železniškimi varnostnimi standardi.
Ob upoštevanju zgornjega odstavka programska oprema spada na področje uporabe tega standarda, dokler ni na voljo ustreznega standarda za programsko opremo na voznih sredstvih.
OPOMBA: Standard za programsko opremo na voznih sredstvih (razen programske opreme za nadzor in zaščito vlakov) je v pripravi.

Introduction
This standard is applied in the design, manufacturing, testing of any electronic equipment installed on
board rolling stock.
It also describes the electrical and environmental operating conditions.
There are not correlations between the operating temperature classes listed in Table 1 and the air
temperature classes listed in EN 50125-1:2014, Table 2.
The aim of this standard is not to be a detailed guideline for the design of the electronic equipment;
the design is made under the responsibility of the supplier. The supplier should take into account the
requirements resulting from the specific location of the on board installation (see Annex C).
This standard contains the design, the documentation and the testing requirements.
The roles of user and/or supplier are shown in Figure 1 below.
