Test Services

We offer a series of test services to ensure that our technical components always perform, flawlessly, even in the toughest of conditions. In addition, our in-house teams evaluate how humidity, temperature, and electrical fluctuations impact equipment during air travel.

Temperature Humidity Chamber

Aerospace components are exposed to extreme conditions during flight including quick temperature changes which effect humidity levels as well. We conduct fully automated and individual temperature and humidity tests in our Temperature Humidity Chamber as well as parallel electrical tests to guarantee dependable operation.

Electrical Tests

Electrical components installed in aircraft are exposed to all types of conditions, including changes in frequency and power, power interrupts and or spikes. AES performs extensive electrical tests for these specific situations. Naturally, all our tests are ABD-compliant and fulfil the RTCA DO-160 standard.

Associated with the ZARM Test Center

AES works closely with the ZARM Test Center that is also located in Bremen. This close cooperation extends our variety of qualification and test services. With its broad range of aerospace testing capabilities in vacuum, in extreme and variable thermal environments, under vibration, as well as in hyper- and microgravity you can rely on comprehensive qualification services for your products.
