Railway applications - Windscreens for trains

This European Standard specifies the functional requirements for rail vehicle windscreens, including type testing, routine testing and inspection methods.
For on-track machines (OTMs) when in transport mode (self-propelled or hauled) the requirements of this standard are applicable. OTMs in working configuration are outside the scope of this standard.
Determination of the size, shape, orientation and position of windscreens is outside the scope of this document. These data form part of the windscreen technical specification.
This document applies to windscreens made of laminated glass, which is the most commonly used material but also to other materials, subject to the performance requirements being satisfied.
This document does not specify requirements for the interfaces between the windscreen and the vehicle. Accordingly this document does not address issues relating to: structural integrity and crashworthiness.

Bahnanwendungen - Frontscheiben für Schienenfahrzeuge

Diese Europäische Norm legt die funktionellen Anforderungen für Frontscheiben in Schienenfahrzeugen fest, einschließlich Typprüfung, Serienprüfung und Untersuchungsverfahren.
Für Zweiwegemaschinen (en: on-track machines (OTM)) sind die Anforderungen dieser Norm anwendbar, wenn sie im Transportmodus sind (selbstangetrieben oder geschleppt). Zweiwegemaschinen im Arbeitsmodus fallen nicht in den Anwendungsbereich dieser Norm.
Die Bestimmung von Größe, Form, Ausrichtung und Position von Frontscheiben fällt nicht in den Anwendungsbereich dieser Norm. Diese Angaben sind Teil der technischen Spezifikation der Frontscheiben.
Dieses Dokument gilt für Frontscheiben aus Verbundglas, was das am häufigsten verwendete Material ist, aber auch für andere Materialien, mit denen die Anforderungen an die Frontscheibe erfüllt werden können.
Dieses Dokument legt keine Anforderungen für die Schnittstellen zwischen Frontscheibe und Fahrzeug fest. Folglich behandelt dieses Dokument nicht Themen der Fahrzeugstruktureigenschaften und des Crashverhaltens.

Applications ferroviaires - Vitres frontales pour trains

La présente Norme européenne spécifie les exigences fonctionnelles relatives aux vitres frontales des véhicules ferroviaires, y compris les essais de type, les essais de série et les méthodes d'examen associées.
Pour les engins de voie (OTM, On Track Machine) en mode transport (machines automotrices ou remorquées), les exigences de la présente norme sont applicables. Les engins de voie en configuration de travail ne relèvent pas du domaine d'application de la présente norme.
La détermination des dimensions, de la forme, de l'orientation et de la position des vitres frontales ne relève pas du domaine d'application de la présente norme. Ces données sont indiquées dans la spécification technique de la vitre frontale.
Le présent document s'applique aux vitres frontales composées de verre feuilleté (matériau le plus couramment utilisé), mais aussi à d'autres matériaux sous réserve qu'ils respectent les exigences de performances.
Le présent document ne spécifie pas les exigences relatives aux interfaces entre la vitre frontale et le véhicule. Par conséquent, le présent document ne traite pas des questions relatives à l'intégrité structurelle et à l'aptitude à la collision.

Železniške naprave - Vetrobranska stekla za vlake

Ta evropski standard določa funkcionalne zahteve za vetrobranska stekla za vlake, vključno s tipskim preskušanjem, rutinskim preskušanjem in metodami nadzora.
Zahteve iz tega standarda se uporabljajo za tirne stroje (OTM), ko so v načinu transporta (samognani ali vlečeni). Področje uporabe tega standarda ne zajema tirnih strojev v delovni konfiguraciji.
Določanje velikosti, oblike, usmerjenosti in položaja vetrobranskega stekla ne spada na področje uporabe tega dokumenta. Ti podatki so del tehnične specifikacije za vetrobranska stekla.
Ta dokument se uporablja za vetrobranska stekla iz lepljenega stekla, ki je najpogosteje uporabljen material, in tudi drugih materialov, ki morajo izpolnjevati zahteve glede zmogljivosti.
Ta dokument ne določa zahtev za vmesnike med vetrobranskim steklom in vozilom. Skladno s tem ta dokument ne obravnava vprašanj v zvezi s strukturno celovitostjo in zagotavljanjem pasivne varnosti pri trčenju.

1 Scope

This document specifies the functional requirements for rail vehicle windscreens, including type

testing, routine testing and inspection methods for high speed rail, heavy rail, light rail and metro

applications.
This document is also applicable for tram vehicles.

For on-track machines (OTMs) when in transport mode (self-propelled or hauled) the requirements of

this standard are applicable. OTMs in working configuration are outside the scope of this document.

Determination of the size, shape, orientation and position of windscreens is outside the scope of this

document. These data form part of the windscreen technical specification.

This document applies to windscreens made of laminated glass, which is the most commonly used

material but also to other materials, subject to the performance requirements being satisfied.

This document does not specify requirements for the interfaces between the windscreen and the

vehicle. Accordingly this document does not address issues relating to: installation, structural integrity

and crashworthiness.
