The DIN EN ISO 9100 defines the framework for comprehensive quality management systems for suppliers of the aerospace industry and the aviation industry suppliers on the basis of the general quality management standards of DIN EN ISO 9001. It is technically equivalent to the standards SAE AS 9100/9110/9120 (America) and the JISQ 9100 (Japan, in part, Asia).
The series of standards was drawn up and installed in 1999 by the Society of Automotive Engineers (SAE in the United States) and the European Association of Aerospace Industries.
Walther has been certified according to this standard since 1994.
