As the general economical situation improved the need for repair decreased. Mr Fuchs therefore changed the main focus of his young company to testing equipment for vehicles. Renaming the company was a logical consequence. In the early fifties, TEST-FUCHS also started to market its products outside the local area and won the Austrian Army as a customer.
Parallel to the reconstruction of the German aviation industry in the early sixties, TEST-FUCHS started to design and manufacture test equipment for aircraft components and was able to position itself as one of the leaders in this area.
