16、 (DIN Standards Committee Railway). Adhesive bonding is a process essential to the production of railway vehicles and their components. Railway vehicles within the meaning of this standard are defined in DIN 25003. The DIN 6701 series of standards gives specifications relating to this process, which

17、 are based on the generic standards for adhesive bonding and take the requirements specifically relevant to rail vehicle construction into account. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN and/or DKE shall not be held r

18、esponsible for identifying any or all such patent rights. DIN 6701 Adhesive bonding of railway vehicles and parts consists of the following parts: Part 1: Basic terms, basic rules Part 2: Qualification of manufacturers of adhesive bonded materials Part 3: Guideline for construction, design and verif

19、ication of bonds on railway vehicles Part 4: Manufacturing controls and quality assurance NOTE This standard does not establish specific design methods or reduction factors so as not to hinder developments for new design methods or new adhesives or to hamper innovations developed by rail vehicle man

20、ufacturers or operators and by adhesive manufacturers. Amendments This standard differs from DIN 6701-2:2006-05 as follows: a) a classification of bonds has been included. Previous edition DIN 6701-2: 2006-05 DIN 6701-3:2015-12 5 1 Scope This standard applies to the adhesive bonding and sealing of a

21、dherends in the manufacture and repair of railway vehicles (“rail vehicles”, for short) and their components. The scope is as laid down in DIN 6701-2. DIN 6701-3 describes the procedures to be followed in the design and verification of bonds made using metallic or non-metallic materials in the manuf

22、acture and repair of rail vehicles and their components. The aim of the design, dimensioning and verification is to ensure proper bonding with due consideration being given to any effects arising from geometry, material and agents used. 2 Normative references The following documents, in whole or in

43、ty classes A1 to A3 and Z, as shown in Table 1, according to the relevant safety requirements. It shall be the designers responsibility to classify bonds with respect to the potential effects of any abrupt and complete failure of the adhesive bond. This also applies to repair work on bonds or by bon

44、ding. The relevant classes are to be entered in all design, manufacturing and repair documents. The responsible designer shall consult with the bonding supervisor in charge for this. Classification into classes A1 to A3 and Z is to be justified, and documented (see Table 2). Where in the documentati

45、on only one class is to be found, this class will apply to all bonded assemblies. 4.2 Classification according to level of safety requirements The required safety is derived from the relevance a rail vehicle assembly or component and a particular bond has for the safety to be provided by a rail vehi

46、cle in terms of protecting persons, equipment and the environment. It shall be up to designer, following consultation with the bonding supervisor in charge, to leave a bond unclassified. DIN 6701-3:2015-12 8 Table 1 Classification of bonds Class Description Level of safety requirement A1 Bonds on ra

47、il vehicles and their components with high-level safety requirements High level Failure of the bond will lead to an inevitable hazard to life or limb, or will constitute a hazard to the safe operation of a rail vehicle. A2 Bonds on rail vehicles and their components with medium-level safety requirem

48、ents Medium level Failure of the bond can lead to a hazard to the safe operation of a rail vehicle involving personal injury, or compromise its function as a whole. A3 Bonds on rail vehicles and their components with low-level safety requirements Low level Failure of the bond will affect comfort at

49、the most, any personal injury being unlikely. Z Bonds on rail vehicles and their components with no safety requirements No safety requirement Failure of the bond will not lead to personal injury nor adversely affect the safe operation of the vehicle. 5 Requirements profile At the design stage, a requirements profile for the
