Quality Assurance


Quality is the key to customer satisfaction. We are proud to hold vendor approval from many of the world's leading industrial companies as well as major third party registration.

E-T-A is the only manufacturer in Germany to hold the „Certificate of Qualification“ of Underwriters Laboratories Inc. (UL) in the USA. This allows us to conduct our own circuit breaker qualification testing to UL standard 1077.
Our Quality Assurance system met the stringent AQAP requirements for a period extending over several decades.
We were one of the first companies to be registered to DIN ISO 9001, which was a precondition to obtaining such further important certifications as BDLI and EASE (European Aerospace Supplier Evaluation) in Germany.
We hold A1 Primary Company Approval from the UK Civil Aviation Authority.
CE marking, the German logo for environmentally sustainable goods, and the accredition of our test laboratory by DATech provide further proof of our competence.
In 2002 E-T-A obtained ISO 9001:2000 certification as well as approval to the aircraft industry standard E DIN EN 9100.
