Railway applications - Adhesive bonding of rail vehicles and their components

This document defines the general terms and basic requests for adhesive bonding and sealing work as well as the requirements placed on adhesive users (hereafter called user-companies) and represents the state of the art for organizing adhesive bonding and sealing processes in the railway industry.
This document applies for adhesive bonding and sealing adherends for:
-   the development of rail vehicles and its components    (pre-production),
-   production of rail vehicles and its components    (in-production),
-   the maintenance incl. repair of rail vehicles and its components   (post-production), and
-   the quality assurance of production, inspection, maintenance incl. repair of rail vehicles and its components.
This document is valid for every adhesively bonded joint in railway vehicles and its components independent of the material of the adherend. It is also valid for all kinds of adhesives independent of their solidification mechanism, their strength and their deformation properties.
This document is not valid for:
-   screw retention by the usage of adhesives, if a pure screw assembly of the same design is sufficient for the purpose,
-   hybrid joints, if the expected function is given exclusively by another joining technology e.g., welding, screwing, riveting,
-   production of vulcanizates which do not lead to adhesively bonded joints,
-   production of plywood,
-   production of fibre reinforced plastic composites (FRP-composites),
-   production of laminated sheet glass (LSG),
-   pure encapsulating of electronic parts, and
-   single-sided adhesive decorative films.

Bahnanwendungen - Kleben von Schienenfahrzeugen und deren Komponenten

Dieses Dokument legt die allgemeinen Begriffe und Grundregeln für Kleb- und Dichtarbeiten sowie die Anforderungen an Anwender von Klebstoffen fest (im weiteren Verlauf "Anwenderbetriebe" genannt) und gilt als Stand der Technik für die Organisation von Kleb- und Dichtprozessen in der Eisenbahnindustrie.
Dieses Dokument gilt für Kleb- und Dicht-Fügeteile für:
-   die Entwicklung von Schienenfahrzeugen und ihrer Komponenten    (Vorproduktion),
-   die Herstellung von Schienenfahrzeugen und ihrer Komponenten    (während der Produktion),
-   die Instandhaltung und Instandsetzung von Schienenfahrzeugen und ihrer Komponenten   (nach der Produktion) und
-   die Qualitätssicherung der Herstellung, Inspektion, Instandhaltung und Instandsetzung von Schienen¬fahrzeugen und ihrer Komponenten.
Dieses Dokument gilt für alle Klebverbindungen von Schienenfahrzeugen und ihrer Komponenten unabhängig vom Werkstoff des Fügeteils. Sie gilt außerdem für alle Arten von Klebstoffen unabhängig von ihrem Aushärtungsmechanismus, ihrer Festigkeit und ihren Verformungseigenschaften.
Dieses Dokument gilt nicht für
-   Schraubensicherungen unter Einsatz von Klebstoffen, wenn eine reine Schraubenverbindung derselben Konstruktion für den Zweck ausreichend wäre,
-   Hybridverbindungen, wenn die erwartete Funktion ausschließlich durch eine andere Fügetechnik wie etwa Schweißen, Schrauben, Nieten erzielt wird,
-   die Herstellung von Vulkanisaten, die nicht zu Klebverbindungen führen,
-   die Herstellung von Sperrholz,
-   die Herstellung von Faserverbund-Kunststoff-Formteilen (CFK),
-   die Herstellung von Schichtglas (LSG),
-   den reinen Verguss von Elektronikteilen und
-   einseitige dekorative Klebfolien.

Le présent document est applicable à tous les joints fixés par adhésion des véhicules ferroviaires et de leurs composants, quel que soit le matériau du support. Il s'applique aux adhésifs de tous types, quels que soient leur mécanisme de solidification, leur pouvoir adhérent et leurs propriétés de déformation.
Le présent document n'est pas applicable dans les cas suivants :
-   retenue de vis par l'usage d'adhésifs, si un assemblage par vissage de même conception suffit ;
-   joints hybrides, si la fonction attendue est exclusivement remplie par une autre technologie d'assemblage telle que le soudage, le vissage, le rivetage ;
-   production de produits vulcanisés qui ne servent pas à la réalisation de joints fixés par adhésion ;
-   production de contreplaqué ;
-   production de matériaux composites plastiques renforcés de fibres (composites PRF) ;
-   production de verre feuilleté (VF) ;
-   simple encapsulage de pièces électroniques ; et
-   films décoratifs adhésifs simple face.

Introduction
Historically, the production of railway vehicles and their components, for the main part, comprises such
materials as steels and aluminium alloys. Their methods of construction and assembly include such
processes as bolting, riveting, and welding.
Railway vehicles within the meaning of this document are defined in EN 15380-1 [47].
Technological developments have led to the availability of other materials, e.g. composites, and some of
these traditional methods of construction as bolting, riveting, and welding and assembly are not
necessarily appropriate or suitable for such materials.
For this reason, a process of adhesive bonding can be essential for the production of certain railway
vehicles and their components, not only in the case of composites but for steels and aluminium alloys as
well as glass and other materials.
The confirmation of the quality and integrity of the final adhesively bonded joints do not readily lend
themselves to traditional inspection and testing techniques such as non-destructive testing.
Therefore, it is essential that the quality and control of the adhesively bonded joints of assemblies and
components is managed to the best possible level by means of an appropriate process control procedure.
Whilst there are standards that deal with Quality Control and are taken into account, this document aims
to give the correct framework and includes additional detail necessary for all adhesive bonding and
sealing activities performed on railway vehicles and its components as a special process.
NOTE EN ISO 9001 [41] is such an example.
Against this background, this document refers to definitions as well as organisational, management,
contractual and technical principles to be followed in production of adhesively bonded joints in analogy
to welding technology. Thus, comparable focal points are also the focus here:
Focal point 1: Classification of each adhesively bonded joint according to safety requirements (see
5.3.2).
Focal point 2: Designation of supervisory personnel (Adhesive Bonding Coordinators - ABCs) and
execution personnel (Adhesive Bonding Operators) who can objectively demonstrate
that they have the necessary and required skills, knowledge, and experience in the field
of adhesive bonding (see Clause 4).
Focal point 3: Verification that the actual loading (stress, strain, and strain energy) of an adhesively
bonded joint during the use of an adhesively bonded product is in any case less than the
maximum load capacity (see 5.4 and Annex D).
Another focus of this document are the principles of workmanship of adhesively bonded joints (see
Clause 6).
