VDA 6.1 is a German quality management system standard.
The first VDA standard was for the exchange of surface models, and was named "VDA-FS".
It has been superseded along the way, by a subset of the "Initial Graphics Exchange Specification" (IGES); referred to, simply, as "VDA".
Based on ISO 9001:1994, the quality management system includes all elements of QS-9000, with an additional four requirements specific to VDA 6.1 as follows: The VDA standard is broken into two parts: Any company seeking certification must achieve at least 90 percent compliance in a formal quality audit.
Sanctioned interpretations of VDA 6.1 are available, clarifying some of the elements, so as to assist companies and registrars to understand the requirements better.
