Railway applications - Railway rolling stock cables having special fire performance - Guide to use
This European Standard gives guidance in the safe use of rolling stock cables specified in EN 50264, EN 50306 and EN 50382.These cables shall only be used for the wiring of railway rolling stock and within the limits given in the manner described in this European Standard. All these cables are for fixed installation where there is no free movement of cable, except for stresses due to typical service. This European Standard is to be applied in conjunction with the relevant product and installation standards. Stricter requirements than those given in this standard could be necessary; see in particular EN 50343. This European Standard is not applicable to: – intercarriage jumpers; – cables subject to continual flexing; – pantograph cables; – coaxial, data and fibre optic cables; – wire wrap; – cables rated at voltages greater than 3,6/6 kV; – applications other than the cabling of railway rolling stock; – cables requiring circuit integrity. Legal or statutory requirements do take precedence over the guidance given in this document. In cases where no guidance exists or where it cannot be derived from general information, it is recommended that advice shall be sought from the cable manufacturer.

La présente Norme européenne donne des lignes directrices pour l'utilisation en toute sécurité des câbles pour matériel roulant spécifiés dans les EN 50264, EN 50306 et EN 50382. Ces câbles sont uniquement utilisés pour le câblage du matériel roulant ferroviaire et dans les limites données de la manière décrite dans la présente Norme européenne. Tous ces câbles sont destinés à une installation fixe dans laquelle il n'y a aucun déplacement libre du câble, à l’exception de celui lié aux contraintes dues au fonctionnement normal. La présente Norme européenne est appliquée conjointement avec les normes pertinentes de produit et d'installation. Des exigences plus strictes que celles données dans cette norme pourraient être nécessaires ; voir en particulier l'EN 50343. Cette Norme européenne n'est pas applicable aux: – câbles de liaison inter-rames; – câbles soumis à des flexions continuelles; – câbles des pantographes; – câbles coaxiaux, de données et à fibres optiques; – faisceaux de fils; – câbles prévus pour des tensions supérieures à 3,6/6 kV; – applications autres que le câblage du matériel roulant ferroviaire; – câbles nécessitant l'intégrité des circuits. Les exigences légales ou réglementaires sont prioritaires par rapport aux lignes directrices données dans ce document. En l'absence de lignes directrices ou bien si celles-ci ne peuvent pas être déduites des informations générales, il est recommandé de demander conseil au fabricant du câble.
Železniške naprave - Kabli (in ožičenje) s posebno požarno odpornostjo v železniških vozilih - Vodilo za uporabo
Ta evropski standard vsebuje navodila o varni uporabi kablov v železniških vozilih iz standardov EN 50264, EN 50306 in EN 50382. Ti kabli se uporabljajo le za ožičenje železniških vozil in v okviru omejitev, ki so opisane v tem evropskem standardu. Vsi taki kabli so namenjeni stalni napeljavi brez prostega gibanja kablov z izjemo obremenitev, ki jih prinaša običajna uporaba. Ta evropski standard se uporablja v povezavi z ustreznim izdelkom in standardi namestitve. Morda so potrebne strožje zahteve od teh, ki so navedene v tem standardu; glej zlasti standard EN 50343.

Introduction
The railway industry is generally concerned with the movement of people as well as goods. It
is therefore essential that safety is achieved, even when failures occur which may involve fire,
however caused, affecting railway rolling stock.
Hence it is necessary to provide cables for use in railway environments which minimise the
hazard to people when a fire may damage the cable, irrespective of whether the fire is caused
by an external source or from within the electrical system.
The aims of this European Standard are to:
– inform railway vehicle manufacturers, installers of cables and railway operators of the
properties and limiting conditions of rolling stock cables in order to safeguard life and
equipment;
– avoid misuse of rolling stock cables.
The information is given as limiting values and illustrated by examples which cannot be
exhaustive but nevertheless indicate ways by which safety (a tolerable level of risk) can be
obtained.
It has been assumed in the preparation of this guidance document that the execution of its
provisions will be entrusted to appropriately qualified and experienced people, for whose use
it has been produced.
This European Standard should be used in conjunction with:
EN 50264 series, Railway applications — Railway rolling stock power and control cables
having special fire performance
EN 50306 series, Railway applications — Railway rolling stock cables having special fire
performance — Thin wall
EN 50382 series, Railway applications — Railway rolling stock high temperature power
cables having special fire performance
EN 50343, Railway applications — Rolling stock — Rules for installation of cabling
1 Scope
This European Standard gives guidance on the safe use of rolling stock cables specified in
EN 50264, EN 50306 and EN 50382.These cables will only be used for the wiring of railway
rolling stock and within the limits given in the manner described in this European Standard. All
these cables are for fixed installation where there is no free movement of cable, except for
stresses due to typical service.
This European Standard will be applied in conjunction with the relevant product and
installation standards. Stricter requirements than those given in this standard could be
necessary; see in particular EN 50343.
This European Standard is not applicable to:
– intercarriage jumpers;
– cables subject to continual flexing;
– pantograph cables;
– coaxial, data and fibre optic cables;
– wire wrap;
– cables rated at voltages greater than 3,6/6 kV;
– applications other than the cabling of railway rolling stock;
– cables requiring circuit integrity.
Legal or statutory requirements do take precedence over the guidance given in this document.
In cases where no guidance exists or where it cannot be derived from general information, it
is recommended that advice be sought from the cable manufacturer.
