VDA 6.1:2003 is a German set of regulations for the automotive industry applicable for suppliers of German automobile manufacturers.
Having been developed by the German Verband der Automobilindustrie e.V. (VDA, Association of Automotive Industry Manufacturers), it was updated and published in its fourth edition in 2003. VDA 6.1:2003 is based on ISO 9001:2000, with its requirements presented in two separate sections:
- Business Management (U Section)
- Product and Process (P Section)
This distinction between sections clearly demonstrates that VDA 6.1:2003 has been structured along process-oriented lines for a number of years.
- to improve corporate strategy
- to improve your company's chain of added value
- customer satisfaction
- constant improvement of processes
VDA Vol. 2 (PPF = Production Process and Product Approval Process)
This is a structured procedure for sampling serial-production components in the automotive field. This is represents the German variant of the PPAP documentation.
The term 'vulcanisation' is used to describe the procedure for the production of elastomers from rubber by a process of wide-meshed chemical cross-linking. The creation of covalent links between the rubber chains can be undertaken in the form of variety of chemical reactions. The most important method remains cross-linking with sulphur cross-linking systems, with peroxide cross-linking the second most commonly used method.
VW – TL 2.8.1
This VW standard is the most frequently used testing specification for elastomers. The standard sets out material requirements and tests for elastomers in automotive applications. The various tests are differentiated on the basis of the main contact medium and classified by the attribution of reference code letters.
Example: VW 2.8.1 T 70
The T stands for Diesel fuel as per TL 788 and biodiesel as per DIN V 51606.
