Pure temperature storage and tests for solvent and dishwashing resistance can be carried out in a heating cabinet with a test chamber volume of 400 l. This operates in a temperature range of + 30 °C to + 250 °C. It is also possible to program different temperature programs with several ramps and holding phases, in addition to maintaining a constant temperature. Here, heat-induced delamination processes can be investigated and described. It is also possible to condition larger samples in this warming box before other tests.
