Tests

In its internal laboratory, Ensinger has available a range of possibilities for determining material characteristics. The table provided offers an overview of possible tests, which can also be performed within the framework of a works test certificate 3.1 in accordance with DIN EN ISO 10204.

In addition, we work in close cooperation with various external test institutes, through which additional and also more complex tests can be performed in a variety of areas.
