CEN shall not be held respon
22、sible for identifying any or all such patent rights.Any feedback and questions on this document should be directed to the users national standards body. A complete listing of these bodies can be found on the CEN website.According to the CEN-CENELEC Internal Regulations, the national standards organi

Their metho
25、ds 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 method
26、s 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
27、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
28、 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 fr
29、amework 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, manage
30、ment, 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 53.2)Focal p
31、oint 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 Ofadhesive bonding (see Clause 4).Focal po
32、int 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 ad
33、hesively bonded joints (see Clause 6).1 ScopeThis document defines terms and specifies requirements for adhesive bonding and sealing work in rail vehicles and their components independent of the material of the adherend and the solidification mechanism, strength, and deformation properties of the ad
34、hesives.This document is applicable to adhesive bonding and sealing adherends in the:development (pre-production);production (in-production; maintenance including repair (post-production); quality assurance of production, inspection, maintenance including repair of rail vehicles and their components
35、.This document is not applicable to: screw retention by the usage of adhesives, if a screw assembly without further safeguard of identical joint design is sufficient for the purpose; hybrid joints, if the expected function is given exclusively by another joining technology e.g. welding, screwing, ri
36、veting; production of vulcanizates; production of plywood; production of fibre reinforced plastic composites (FRP-composites); production Oflaminated safety glass; pure encapsulating of electronic parts; application of single-sided adhesive decorative films.2 Normative referencesThe following docume
