Classification of bonded joints
Table 1 classifies bonded joints on rail vehicles and on components and parts of rail vehicles as a function of the relevant safety requirements. The classification of the bonded parts into part classes is based on the potential effect of failure of the bonded joint as stated by the relevant design companies/engineers. The same applies for repairs to bonded joints and for repairs realized by adhesive bonding. The part classes must be indicated on drawings. The relevant design engineer must involve the supervisor in charge of the bonding work (SIC) in the process of assigning bonded parts to classes.

DIN 6701-2:2006-05
Foreword This standard was developed from NA 087 05-06 AA “Adhesive Bonding Technology in Rail Vehicle Construction” of the Railway Vehicle Standard s Committee (FSF). Adhesive bonding is a key process in the manufacture of rail vehicles and parts of rail vehicles. The standards in the DIN 6701 series specify the requirements for “adhesive bonding”, a so-called special process. These requirements are based on the technical standards for adhesive bonding, taking into account the special needs for rail vehicle construction. The standards in the DIN 6701 series “Use of adhesive bonding in the manufacture of rail vehicles and parts of rail vehicles” comprise: - Part 1: Basic terms and basic regulations - Part 2: Qualification of adhesive users (hereafter called user-companies) and compliance evaluation - Part 3: Design specifications (in preparation) - Part 4: Regulations for manufacturing adhesive bonds and quality assurance (in preparation)

Area of application
This standard applies for bonding and sealing substrates for manufacturing and repairing rail vehicles and parts of rail vehicles. It defines the general terms and basic regulations for bonding and sealing work. It: - assigns parts to classes - defines the requirements placed on user-companies - describes the procedure for accrediting user-companies and - describes the procedure for compliance evaluation. 2 Reference standards

This class applies to companies which has no own production of bonded parts but which - designs or - purchases and sells on or - purchases and fits bonded parts assigned to classes A1 and A2.
Depending on the class of bonded joint, the user-company must possess adequately trained employees to carry out and supervise the bonding work and test the resulting bonded joints. The degree of training required to meet the quality obligations depends on the specific classification of the rail vehicles and rail vehicle parts. Safety considerations demand that suitably trained employees can guarantee the appropriate quality assurance. The qualifications mentioned in the standard for example purposes are a guideline for the degree of training that is required. In individual cases the actual level of knowledge required of specific areas may be greater or less. With regard to the former, additional training may be required. With regard to the latter scenario, special training courses geared to specific rail vehicle parts may prove unnecessary, meaning they can be omitted. Deviations from the levels of training mentioned herein for example purposes must be reasoned in each individual case. 4.2.2 Technical knowledge
