Railway applications - Track - Concrete sleepers and bearers with under sleeper pads

This European Standard is applicable to concrete sleepers or bearers with Under Sleeper Pads (USP) physically bonded to concrete used in ballast track and define the test procedures and their evaluation criteria. This standard provides particular information in the following areas:
- test methods, test arrangements and evaluation criteria of Under Sleeper Pads;
- test methods, test arrangements and evaluation criteria of concrete sleepers and bearers with Under Sleeper Pads;
- data supplied by the purchaser and by the supplier;
- definition of general process of design approval tests;
- definition of routine tests.
This standard defines the specific test procedures for design approval tests, routine tests and tests concerning the determination of relevant properties of Under Sleeper Pad with or without concrete sleepers and bearers:
- fatigue tests;
- tests of capability for stacked stocking of concrete sleepers or bearers fitted with USP;
- pull-out test;
- severe environmental condition test.
This standard also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This standard does not, however, contain requirements pertaining to the properties of Under Sleeper Pads. It is the responsibility of the purchaser to define these requirements

Bahnanwendungen - Oberbau - Gleis- und Weichenschwellen aus Beton mit Schwellensohlen

Dieses Dokument ist anwendbar für Schwellensohlen (USP, en: under sleeper pads) an Gleis- oder Weichenschwellen aus Beton, welche physikalisch mit dem Beton der Schwelle verbunden sind und im Schotterbett verwendet werden, und legt die Prüfverfahren sowie die Bewertungskriterien fest. Diese Norm enthält spezielle Angaben über folgende Bereiche:
 Prüfverfahren, Prüfanordnungen und Bewertungskriterien für Schwellensohlen;
 Prüfverfahren, Prüfanordnungen und Bewertungskriterien für Gleis- und Weichenschwellen aus Beton mit Schwellensohlen;
 Angaben die vom Kunden und vom Lieferanten bereitzustellen sind;
 Definition des allgemeinen Prozesses für Bauartzulassungsprüfungen;
 Definition von Prüfungen zur Qualitätssicherung (Regelprüfungen).
Dieses Dokument legt die speziellen Prüfverfahren für Bauartzulassungsprüfungen und Prüfungen zur Qualitätssicherung sowie die Prüfungen fest, die die Bestimmung der maßgeblichen Eigenschaften von Schwellensohlen mit oder ohne Gleis- und Weichenschwellen aus Beton betreffen:
 Ermüdungsprüfungen;
 Prüfungen der Stapelfähigkeit von Gleis- oder Weichenschwellen aus Beton mit USP;
 Abreißprüfung;
 Prüfung der Temperaturschwankungen.
Dieses Dokument legt auch Verfahren zur Prüfung der Gebrauchstauglichkeit fest und sie enthält Informationen hinsichtlich der Qualitätsüberwachung als Teil der Verfahren zur Qualitätssicherung. Diese Norm enthält hingegen keine Anforderungen, welche die Eigenschaften von Schwellensohlen betreffen. Es liegt in der Verantwortung des Kunden, diese Anforderungen festzulegen.

Applications ferroviaires - Voie - Traverses et supports en béton avec semelles sous traverse

Le présent document s'applique aux traverses ou aux supports en béton, avec une semelle sous traverse (USP) physiquement liée au béton, posés sur les voies ballastées et définit les modes opératoires d'essai et leurs critères d'évaluation. Le présent document donne des informations particulières dans les domaines suivants :
— méthodes d'essai, montages des essais et critères d'évaluation des semelles sous traverse ;
— méthodes d'essai, montages des essais et critères d'évaluation des traverses et des supports en béton avec semelle sous traverse ;
— données fournies par l'acheteur et par le fournisseur ;
— définition des processus généraux des essais de qualification ;
— définition des essais de série.
Le présent document définit les modes opératoires d'essai spécifiques pour les essais de qualification et les essais de routine mais aussi les essais permettant de déterminer les propriétés pertinentes des semelles sous traverse avec ou sans traverse et support en béton :
— essais de fatigue ;
— essais de capacité de stockage vertical des traverses ou des supports en béton équipés d'USP ;
— essai d'arrachement ;
— essai de variation de température.
Le présent document établit également des modes opératoires pour les essais d'aptitude à l'emploi et fournit des informations sur la gestion de la qualité dans le cadre des procédures d'assurance qualité. Toutefois, le présent document ne contient pas d’exigences relatives aux propriétés des semelles sous traverse. Il est de la responsabilité de l’acheteur de définir ces exigences.
