As is the case with other standards, DIN is basically concerned with ensuring that manufacturers:.

DIN establishes 4 types of unions according to their criticality and impact that can lead to failure:. A3 – Unions executed in rail vehicles involving low safety requirements which can cause a decline in the comfort of the vehicle without causing injury.
The training course of European Adhesive Bonder consists of 40 hours of theory and practices focused on the proper execution of any adhesive bonding taking into account cin the parameters that influence to ensure diin quality of the adhesive bond. Work instructions for the production of effective bonded joints and repair instructions for bonded joints must be available see Annex D.
It defines the general terms and basic regulations for bonding and sealing work. The responsibilities given in Table 3 can be linked to a number of tasks such as; Precise details or preparation; Coordination; Monitoring; Inspection or release. The decision about this rests with the certification body.
DVS -EWF – Equivalent b qualification Employees supervising adhesive bonding work Completed course in one of the natural or engineering sciences at a technical college or university. Basic terms and basic regulations – Part 2: For repairing rail vehicles, Level 2 suffices if it has been ensured that no decision-making authority in the area of design and production preparation is required. For part classes A1 to A3, the minimum required qualification is Level 3.
Additionally, a successfully completed course at an accredited training establishment. The production equipment for the adhesive bonding activities must be suitable for the intended uses. Table 4 — Evaluation of compliance Part class A1 and A2 Description of the evaluation of compliance The customer orders with compliance testing by an agreed certification body: The degree of training required to meet the quality obligations depends on the specific classification of the rail vehicles and rail vehicle parts.
Employees supervising the adhesive bonding work and equally qualified deputies for all part classes. A2 – Unions executed in rail vehicles means involving safety requirements which can cause personal harm or damage during operation. Tasks carried out by such delegated parties are also the ultimate responsibility of the employee in charge of supervising adhesive bonding work SIC in accordance with this standard see Table 3.
Regulations for manufacturing adhesive bonds and quality assurance in preparation 1 Area of application This standard applies for bonding and sealing substrates for manufacturing and repairing rail vehicles and parts of rail vehicles. The validation of the availability of work instructions and repair instructions via checks can be carried out by: Such persons, who are also responsible for the quality assurance tasks, must possess adequate authority in order to be able to give orders for all necessary measures.
The supervision of the adhesive bonding work is the responsibility of the user-company. Employees carrying out practical adhesive bonding work 3 Technical knowledge, for example: If one of the above conditions is not fulfilled, then a new accreditation procedure must take place.
In individual cases the actual level of knowledge required of specific areas may be greater or less. An equally qualified deputy Level 1 is not required for smaller user-companies user-companies with little production involving adhesive bonding, one production area involving adhesive bonding.
A1 – Unions executed in rail vehicles involving high safety requirements, such elements can cause fatal cases where falls during operation of the vehicle or endanger the operation thereof. Engineering and design Design of adhesive bonding:. These are also required when a company wishes to extend its accreditation to new bonding processes or groups of materials or when changes to the bonding process have taken place. The user-company defines what manufacturing experience, training and technical knowledge are required.
These tasks are responsibilities are defined in Table 3. Level 1 For assembly: The requirements of the relevant official body must be heeded. If there are changes to the details stipulated in the certificate, the certification body must be informed immediately by the user-company. Where date versions are not mentioned, the most recent version of the document applies including all amendments.
Certification for adhesive bonding: DIN 6701-2
Adhesive bonding is a key process in the manufacture of rail vehicles and parts of rail vehicles. Not required Employees for monitoring and testing the quality of the bonded joints in accordance with the prescribed requirements see section 4. These requirements are based on the technical standards for adhesive bonding, taking into account the special needs for rail vehicle construction.
These trials must confirm that the machinery is suitable for carrying out the work in a problem-free way. Table 5 shows the assignment of compliance evaluation procedures for the different part classes. The certification body must check that the process description meets the requirements of this standard. This course is essential for the successful conclusion of all operators executes adhesive bonds governed under DIN The validity can be extended following an audit in accordance with section 6.
For tasks and responsibilities see Table 3.
The evaluation of the results is carried out by the SIC at the company. The same applies for repairs to bonded joints and for repairs realized by adhesive bonding. For repair work at user-companies where operations involve little adhesive bonding, it is permissible for an SIC to be responsible for several user-companies. The classification must be agreed in a written contract between the customer and the user-company. Peel-Ply Dosing using volume e. The appointment of such persons as a deputy for the supervisor in charge is possible in all cases.
