Flacherzeugnisse aus nicht-rostended St? 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.
The requirements of the relevant official body must be heeded. 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 obligations, 6701- and limits of the area of responsibility of such persons must be defined.
The validation of the availability of work instructions and repair instructions via checks can be carried out by: Qualification of user-companies, quality assurance Total number of pages: 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.
An equally qualified deputy Level 601-2 is not required for smaller user-companies user-companies with little production involving adhesive bonding, one production area involving adhesive bonding. The validity can be extended following an audit in accordance with section 6.
Certification for adhesive bonding: DIN 6701-2
These trials must confirm that the machinery is suitable for carrying out the work in a problem-free way. The user-company defines what manufacturing experience, training and technical knowledge are required.
Work instructions for the production of effective bonded joints and repair instructions for bonded joints must be available see Annex D. The certification is specific to a production facility of the user-company and its SICs.
It must be demonstrated that they possess the relevant technical knowledge. Additionally, a successfully completed course at an accredited training establishment. In accordance with Annex Dkn, the user-company must appoint at least one person to supervise the adhesive bonding work. The classification must be agreed in a written contract between the customer and the user-company.
Need advice on DIN ? If one of the above conditions is not fulfilled, then a new accreditation procedure must take place. Where date versions are mentioned, only these are relevant. Application of adhesives Surface preparation Cleaning agents Metals surface preparation Plastic surface preparation Glass surface preparation Plasma.
With regard to the latter scenario, special training courses geared to specific rail vehicle parts may prove unnecessary, meaning they can be omitted. 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.
If there is no qualification 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 technical knowledge.
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 all the parameters that influence to ensure the quality of the adhesive bond.
The certification body must check that the process description meets the requirements of this standard. 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.
With regard to the former, additional training may be required. 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.
All documents relating to qualifications must be kept up to date. In individual cases the actual level of knowledge required of specific areas may be greater or less. The same applies for repairs to bonded joints and for repairs realized by adhesive bonding. The training course European Adhesive Specialist consists of hours where much of the subject taught within the course of European Engineer acquired, specialists have the ability to monitor and define the instructions for proper adhesive bonding, monitor the entire process and the parameters involved and to identify and correct any irregularities.
The European Adhesive Engineer is responsible for ensuring the whole process design, industrialization, implementation and maintenance of any adhesive bonding taking the necessary decisions to ensure the quality of the union. Finally for a company acquires the certificate DIN requires that a competent authority in the matter conduct periodic audits verifying that both staff and the means, resources and management system are appropriate to ensure the quality of any adhesive bonding.
A2 – Unions executed in rail vehicles means involving safety requirements which can cause personal harm or damage during operation.
A3 – Unions executed in rail vehicles involving low safety requirements which can cause a decline in the comfort of the vehicle without causing injury. Peel-Ply Dosing using volume e. For this they must possess the relevant authority to issue orders and decision-making authority independent of production necessities.
As we mentioned DIN is specific to the rail sector, that standard is divided into the following 4 parts:.
Din – Adhesive bonds Railway normative
Defined workplaces for adhesive bonding work see work instructions, repair instructions ; Equipment for surface preparation, e.
For part classes A1 to A3, the minimum required qualification is Level 3. Currently and increasingly companies from various sectors have in their staff with the titles described above, improving day by day knowledge of this matter and ensuring at all times the quality of the adhesive bond. The part classes must be indicated on drawings.
