Qualification of user-companies, quality assurance Total number of pages: Adhesive bonding is a key process in the manufacture of rail vehicles and parts of rail vehicles. These requirements are based on the technical standards for adhesive bonding, taking into account the special needs for rail vehicle construction.
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 1 Idn of application This standard applies for bonding di sealing substrates for manufacturing and repairing rail vehicles and parts of rail vehicles.
Din – Adhesive bonds Railway normative
It defines the general terms and basic regulations for bonding and sealing work. Where date versions are mentioned, only these are relevant.
Where date versions are not mentioned, the most recent version of the document applies including all amendments. 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.
Table 1 — Classification of bonded joints Class A1 Description Bonded joints on rail vehicles and parts of rail vehicles with high safety requirements Examples a – GFRP head to shell – front window in front panel – side windows in carriage body – plating on carriage dn – external parts, equipment boxes on carriages – roof structures – interior furnishings e.
The classification must be agreed in a written contract between the dun and the user-company. The requirements of the relevant official body must be heeded.
In addition, sections 5. 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 ein 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 dih unnecessary, meaning they can be omitted. Deviations from the levels 671-2 training mentioned herein for example purposes must be reasoned in each individual case.
It must be demonstrated that they possess the relevant technical knowledge. The user-company defines what manufacturing experience, training and technical knowledge are required.
That depends on the particular tasks that have been assigned and the responsibility. All documents relating to qualifications must be kept up to date.
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.
Additionally, a successfully completed course at an accredited training establishment. Employees supervising the adhesive 601-2 work and equally qualified deputies for all part classes. Includes Levels 2 and 3. Employees supervising the adhesive bonding work for part class A2 and non equally qualified deputies for part class A1 see Table 3. Employees carrying out practical adhesive bonding work 3 Technical knowledge, for example: Rin carrying out the practical adhesive bonding work independently and effectively following work instructions.
For part classes A1 to A3, the minimum required qualification is Level 3. These tasks are responsibilities are defined in Table 3. Such persons, who are also responsible for 6710-2 quality assurance tasks, must possess adequate authority in order to be able to give orders for all necessary measures. The obligations, interrelationships and limits of the area of responsibility of such persons must be defined.
For tasks and responsibilities see Table 3. Table 3 must be used as a guide for defining the quality-related tasks and the responsibilities of the employees who supervise the adhesive bonding work. There can be additional requirements for special applications. It is unnecessary for all the listed points to be used by all user-companies or for all quality systems.
The responsibilities given in Table 3 can be linked ein a number of tasks such as; Precise details or preparation; Coordination; Monitoring; Inspection or release. In accordance with Annex A, the user-company must appoint at least one person to supervise the adhesive bonding work. The supervision of the adhesive bonding work is the responsibility of the user-company.
For some production tasks, the tasks and responsibilities can be delegated to other parties. Tasks 7601-2 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 Dinn 3.
Table 3 Tasks and responsibilities No. Part class A1 SIC 1. If there is no fin in accordance with the EWF code, the user-company must demonstrate that the supervisory personnel for the area of validity of this standard have equivalent ein knowledge. The area of validity of this standard covers Levels 1 and 2 as described in Table 2. For this they must possess the relevant authority to issue orders and decision-making authority independent of production necessities.
Only authorised deputies having equal or higher qualifications may fully deputise for supervisors in diin. Company owners, managing directors, managers and production managers can only be authorised as supervisors in charge for part class A1 if their company operations involve little adhesive bonding.
The appointment of such persons as a deputy for the supervisor in charge is possible in all cases.
The approval of the primary employer must be given; The work time involved is laid down in a contract and can be clearly demonstrated; The external SIC can only be authorised for one user-company.
For repair work at user-companies where operations involve little adhesive bonding, it is permissible for an SIC to be dim for several user-companies. The decision rin this rests with the certification body. Personnel for monitoring and testing – 4.
Certification for adhesive bonding: DIN 6701-2
The evaluation of the results is carried out by the SIC at the company. Defined workplaces for adhesive bonding work see work instructions, repair instructions ; Equipment for surface preparation, e. The production vin for the adhesive bonding activities must be suitable for the intended uses. These trials must confirm that the machinery is suitable for carrying out the work in a problem-free way.
Where relevant, the trials must be undertaken dih accordance with the pertinent standards or regulations. The reports on such trials must be kept for 5 years. Work instructions for the production of effective bonded joints and repair instructions for bonded joints must be available see Annex D.

The validation of the availability of work instructions and repair instructions via checks can be carried out by: In particular this must cover: The certification body must check that the process description meets the requirements of this standard.
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 dln have taken place. The work checks can be omitted if the user-company can demonstrate the availability of relevant work instructions in accordance with section 4.
The certification is specific to a production facility of the user-company and its SICs. If there are changes to the details stipulated in the certificate, the certification body must be informed immediately by the user-company.
The certification body then takes a decision about the further validity of the certificate. During the period of validity, the certification body monitors that there is compliance with the requirements of this standard, in accordance with the details stipulated on the certificate. After expiry of the period of validity, it is possible for the certification body to extend the validity following an audit of the user-company. The validity can be extended following an audit in accordance with section 601-2.
If one of the ein conditions is not fulfilled, then a new accreditation procedure must take place. If there are changes to the area of 6701-22 of the certificate, a new audit must be carried out by the certification body in accordance with section 6. Table 5 shows the assignment of compliance evaluation procedures for the different part classes.
