Railway applications - Requirements for running capability in case of fire on board of rolling stock
This European Standard defines requirements for running capability under fire conditions which are applicable to passenger carrying railway rolling stock. In particular, technical measures are specified, compliance with which will contribute to conformity with the Directive and the relevant Technical Specifications for Interoperability (TSI). The standard specifies the fire conditions: – for which it is not necessary to define running capability requirements as there is no significant potential for serious injury or threat to life; – for which it is reasonable to expect trains to continue to run in a controlled manner; – for which it is not reasonably practicable to define requirements due to the exceptional nature of the fire incident. The TSI SRT defines running capability requirements in respect of fires within technical areas/equipment only. However for general guidance the scope of this standard is extended to include fires from non-technical causes within passenger/staff areas which may impact train system functions adjacent to and/or passing through the affected area. This extension of applicability significantly increases the number of system functions which are potentially at risk and therefore requires that the "reasonably practicable" principles be extended to this new condition. The standard does not consider situations where a primary non-fire incident is likely to immobilise the train by definition; for example major mechanical defect leading to derailment, even when fire then occurs.

Applications ferroviaires - Exigences en matière d’aptitude au roulement en cas d’incendie à bord des véhicules ferroviaires
La présente Norme européenne définit les exigences en matière d’aptitude au roulement en cas d’incendie, applicables aux véhicules ferroviaires. Elle spécifie notamment des mesures techniques, la conformité à celles-ci contribuant à la conformité à la Directive et aux Spécifications techniques d’interopérabilité (STI) concernées. La norme spécifie les conditions d’incendie: – pour lesquelles il n’est pas nécessaire de définir des exigences d’aptitude au roulement car il n’existe aucun potentiel significatif de blessure grave ou de mise en danger de la vie. – pour lesquelles il est raisonnable de s’attendre à ce que les trains continuent à rouler d’une manière contrôlée; – pour lesquelles il n’est pas raisonnablement possible de définir des exigences en raison de la nature exceptionnelle de l’incendie. La STI STF définit les exigences d’aptitude au roulement pour des incendies ayant lieu seulement au sein des zones/équipements techniques. Toutefois, comme ligne directrice générale, le domaine d’application de la présente norme est étendu aux incendies ayant des causes non techniques au sein des compartiments voyageurs/locaux de service pouvant avoir un impact sur les fonctions de système, adjacents à la zone affectée et/ou la traversant. Cette extension d’applicabilité augmente nettement le nombre de fonctions de système présentant un risque potentiel et nécessite donc l’extension des principes « raisonnablement possibles » à cette nouvelle condition. La norme ne traite pas des situations où un incident déclencheur non lié à un incendie va vraisemblablement conduire par définition à une immobilisation du train; par exemple un défaut mécanique majeur conduisant à un déraillement, même en cas d’incendie.
Železniške naprave - Zahteve za sposobnost vožnje tirnih vozil v primeru požara
Ta evropski standard določa zahteve za sposobnost vožnje v primeru požara, ki se uporabljajo za tirna vozila, ki prevažajo potnike. Opredeljeni so zlasti tehnični ukrepi, pri čemer bo skladnost z njimi pomagala zagotoviti skladnost z direktivo in ustreznimi tehničnimi specifikacijami za interoperabilnost (TSI). Standard določa požarne razmere: – za katere ni treba opredeliti zahtev za sposobnost vožnje, saj ne obstaja velika možnost za resne poškodbe ali življenjsko ogroženost; – za katere je razumno pričakovati, da bodo vlaki še naprej nadzorovano obratovali; – za katere ni razumno izvedljivo opredeliti zahteve, ki v celoti zagotavljajo nadzorovano vožnjo, zaradi izjemne narave požara. Tehnične specifikacije za interoperabilnost v zvezi z varnostjo v železniških predorih določajo zahteve za sposobnost vožnje le za požare znotraj tehničnih območij/opreme. Vendar se za splošne napotke področje uporabe tega standarda razširi na požare zaradi netehničnih razlogov v prostorih za potnike/osebje, ki lahko vplivajo na sistemske funkcije vlaka, ki so poleg in/ali potekajo skozi prizadeto območje. Ta razširitev uporabnosti bistveno poveča število sistemskih funkcij, ki so potencialno ogrožene, zato je potrebno, da se »razumno izvedljiva« načela razširijo na ta novi pogoj. Standard ne zajema primerov, v katerih obstaja verjetnost, da bo nesreča, ki ni požar, sama po sebi povzročila zaustavitev vlaka, na primer obsežna mehanska okvara, ki povzroči iztirjenje, celo kadar nato pride do požara.
