Future detector systems have increasing demands on the performance of their mechanical support structures and cooling systems.
Novel materials and cooling techniques are developed and continuously improved in order to fulfil these requirements.
A custom thermal conductivity measurement setup is presented to measure these materials thermal conductivity.

The setup consists of two heat flux meter blocks between which the samples are clamped.
The setup follows the American Society for Testing and Materials standard D5470-06 and consists of two brass blocks, which act as heat flow meters.

In order to minimize heat exchange between the heat flux blocks and the ambient via convection and radiation, the setup is covered with a radiation shield and measurements are carried out in a vacuum.

The contribution describes the setup in detail, motivates its design aspects and highlights the commissioning and calibration procedure.
The analysis method and calibration procedure are presented.
