Approvals / Certificates
The exceptional quality requirements of the aerospace industry, to ensure optimal product quality and reproducibility, has necessitated that the supplying companies be extensively approved. The approvals take place at national level, the EN 9100 and Nadcap approvals for instance, and are reinforced by the individual company approvals. In most cases the company approvals, which primarily evaluate the quality management systems, are supported by the material qualification programmes in which the ultimate quality of the individual material grades is accessed.

A list of some of the major quality approvals which are held by the Deutsche Edelstahlwerke can be seen as below
•  Airbus Germany •  Airbus UK
•  EADF Aerospatiale Matra Airbus •  Rolls Royce
•  Eurocopter •  Pfalzflugzeugwerke
•  Turbomeca •  Singapore Technology Centre
•  Bombardier / Shorts •  Pratt & Whitney
•  Lord Aerospace •  Westland Helicopter
•  Hawker Beechcraft •  BAE Systems
•  Messier Dowty •  Liebherr
•  GKN Aerospace •  SKF Aerospace
•  Premium Aerotech •  Aircelle*
•  Goodrich* •  Nadcap (AS7102)
•  ISO 9001:2000 •  EN 9100:2003
