Test Chamber for Determining the Stationary Heat Transfer Properties with a Controlled Hotbox in Accordance with DIN EN ISO 8990, DIN EN 1946-4, DIN EN ISO 12567, DIN EN 12412-2, and ASTM C1363; and Combined in Accordance with DIN EN 1934.

The compact test chambers TDW 4140 and TDW 4240 were designed for testing elements and components used
in construction, such as windows, profiles, doors and domes (and in the case of TDW 4240, also brick walls). They
basically simulate the temperature and the natural convection inside and outside a building. Optionally, the
humidity level in the two sections of the chamber can be set as needed. The HotBox software at the measurement
and control unit is used to set all parameters as well as for complete data logging, detailed analysis and printing
of test reports. There are also other devices, accessories and materials available that allow for sample preparation
and conditioning to optimize the testing procedure.
