- Identification & marking: Manufacturer, EN reference, voltage rating, number/size of cores and code designation (Annex A); core identification by numbers or colours to HD 308 / EN 50334.
- Mechanical & environmental tests: Conductor resistance, voltage, insulation resistance, dielectric strength, spark test, ageing, hot set, ozone, mineral oil/fuel/acid/alkali resistance, low temperature bending/impact, compatibility and water absorption.
- Fire test references: Linked test standards (e.g., EN 60332‑1‑2, EN 61034‑2, EN 50266 series, EN 50305) and Part 1 “General requirements”.
Applications and who uses it

Introduction
The EN 50264 series covers a range of cables, based upon halogen free materials, for use in railway rolling
stock. It is divided into 5 parts under the generic title “Railway applications - Railway rolling stock power and
control cables having special fire performance”:
– Part 1 General requirements;
– Part 2-1 Cables with crosslinked elastomeric insulation – Single core cables;
– Part 2-2 Cables with crosslinked elastomeric insulation – Multicore cables;
– Part 3-1 Cables with crosslinked elastomeric insulation with reduced dimensions – Single core
cables;
– Part 3-2 Cables with crosslinked elastomeric insulation with reduced dimensions – Multicore cables.
Information regarding selection and installation of cables, including current ratings can be found in EN 50355
and EN 50343. The procedure for selection of cable cross-sectional area, including reduction factors for
ambient temperature and installation type, is described in EN 50343.
Special test methods referred to in EN 50264 are given in EN 50305.
Part 1, “General requirements”, contains a more extensive introduction to EN 50264, and should be read in
conjunction with this Part 2-2.
1 Scope
EN 50264-2-2 specifies requirements for, and constructions and dimensions of, multicore cables of the
following types and voltage ratings:
• 300/500 V screened or unscreened (1 mm², 1,5 mm² and 2,5 mm², number of cores from 2 to 40);
• 0,6/1 kV screened or unscreened (1,5 mm² to 50 mm², 2, 3 and 4 cores).
NOTE Not all conductor sizes or number of cores are specified for every type.
All cables have class 5 tinned copper conductors to EN 60228, halogen-free insulation and halogen-free
sheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation is
encountered. The requirements provide for a continuous conductor temperature not exceeding 90 °C and a
maximum temperature for short circuit conditions of 200 °C based on a 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.

La norme EN 50264-2-2:2008 traite des câbles d'alimentation et de contrôle pour le matériel roulant ferroviaire ayant des performances spéciales en matière de feu. Son champ d'application est clairement défini, spécifiant les exigences, les constructions et les dimensions des câbles multicœurs, notamment pour les tensions de 300/500 V et de 0,6/1 kV. Les types de câbles concernés varient en fonction de la section des conducteurs, allant de 1 mm² à 50 mm², et comprenant entre 2 et 40 conducteurs. Une mention particulière est faite concernant la taille des conducteurs et le nombre de cœurs, qui ne sont pas spécifiés pour toutes les catégories. Un des points forts de cette norme est l'exigence relative à des conducteurs en cuivre étamé de classe 5, conformément à la norme EN 60228, ainsi que l'utilisation d'une isolation et d'une gaine sans halogène. Ces spécifications assurent non seulement la sécurité et la durabilité des câbles dans le milieu ferroviaire, mais contribuent également à la réduction des risques liés à l'incendie. En matière de performance thermique, la norme stipule que la température continue des conducteurs ne doit pas dépasser 90°C, avec une température maximale en cas de court-circuit de 200°C sur une durée limitée à 5 secondes. Ceci reflète une préoccupation essentielle pour la sécurité dans les applications ferroviaires, où les conditions d'exploitation peuvent être particulièrement exigeantes. De plus, EN 50264-2-2 se distingue par ses performances en cas d'incendie, mettant en avant des caractéristiques telles que la propagation des flammes et l’émission maximale de fumée et de gaz toxiques. Ces exigences sont critiques pour garantir la sécurité des passagers et du personnel à bord des véhicules ferroviaires. Enfin, il est à noter que EN 50264-2-2 doit être interprétée en relation avec la Partie 1, qui traite des exigences générales, ce qui renforce sa pertinence en tant que document de référence pour les professionnels du secteur ferroviaire. En conclusion, cette norme constitue une base solide pour la conception et l'utilisation de câbles multicœurs, en répondant à des enjeux de sécurité essentiels dans le domaine des applications ferroviaires.
