CCM_Lab is equipped with the C-THERM Trident FLEX Transient Plane Source (TPS) instrument which employs a double-sided sensor to determine thermal conductivity. It provides high flexibility and control over experimental parameters, such as test time and parameters. The method conforms to ISO 22007-2 standard.

Samples should be homogenous, shaped samples that have flat, smooth surfaces that sandwich the sensor. The testing technique is non-destructive.

In the assessment of mortar properties and their relation to sustainability, the TPS method is used to evaluate thermal performance, including the material’s ability to act as a thermal insulator. These measurements help optimize mortar formulations to improve building comfort and reduce energy consumption for heating and cooling.

Heat transfer properties are determined in stationary tests with a guarded hot plate setup as well as dynamically with a transient plane source (TPS) setup, which provides apart from thermal conductivity also heat capacity and thermal diffusivity.
