Railway applications - Railway rolling stock cables having special fire performance - Thin wall - Part 3: Single core and multicore cables screened and thin wall sheathed

This document specifies requirements for, and constructions and dimensions of, multicore cables, rated voltage U0/ U = 300/500 V, of the following type: Screened (0,5 mm2 to 2,5 mm2, number of cores from 1 to 8). All cables have stranded tinned copper conductors, and thin wall thickness, halogen-free, insulation and sheath. They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables, this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 110 °C/20 000 h temperature index. If the customer were to require lifetime predictions this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. Under fire conditions, the cables exhibit special performance characteristics in respect of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. These requirements are specified to permit the cables to satisfy Hazard Level 3 of EN 45545 1 and EN 45545 2. EN 50306 3:2020 is expected to be used in conjunction with EN 50306 1:2020, General Requirements, and EN 50306 2:2020, Single core cables.

Bahnanwendungen - Kabel und Leitungen für Schienenfahrzeuge mit verbessertem Verhalten im Brandfall - Reduzierte Isolierwanddicken - Teil 3: Ein- und mehradrige Kabel und Leitungen geschirmt mit reduzierten Mantelwanddicken

Applications ferroviaires - Câbles pour matériel roulant ferroviaire ayant des performances particulières de comportement au feu - Isolation mince - Partie 3 : Câbles monoconducteurs et multiconducteurs blindés avec gaine d'épaisseur mince

Le présent document définit les exigences constructives et dimensionnelles des câbles multiconducteurs, de tension assignée U0/U = 300 V/500 V, du type suivant: Câble blindé (0,5 mm2 à 2,5 mm2, 1 à 8 conducteurs). Tous les câbles sont constitués d'âmes câblées en cuivre étamé, sous enveloppe isolante et gaine sans halogènes d'épaisseur mince. Ils sont destinés aux câblages fixes, ou aux câblages dont les flexions en service sont limitées, dans le matériel roulant ferroviaire. Ces câbles sont conçus pour résister à des contraintes thermiques occasionnelles provoquant un vieillissement thermique équivalent à celui résultant d’un fonctionnement continu à 90 °C. Pour les câbles normalisés, cette température est déterminée par l’essai d’acceptation décrit dans l’EN 50305, qui consiste à appliquer un vieillissement thermique accéléré de longue durée (5 000 h) indiquant un indice de température de 110 °C/20 000 h. Si le client exigeait des prédictions de durée de vie, ces prédictions seraient fondées sur l’indice de température du produit tel que fourni par le fabricant. La température maximale admissible en cas de court-circuit est de 160 °C pendant 5 s. Lorsqu'ils sont soumis au feu, les câbles présentent des caractéristiques de performance particulières quant aux valeurs maximales admissibles relatives à la propagation de la flamme et l'émission de fumées et de gaz toxiques. Ces exigences permettent aux câbles de satisfaire au niveau de risque 3 de l'EN 45545 1 et de l'EN 45545 2. L’EN 50306 3:2020 est prévu pour être utilisé conjointement avec l’EN 50306 1:2020, Exigences générales, et avec l’EN 50306 2:2020, Câbles monoconducteurs.
