Condensation tests

Condensation tests are divided into two main groups: single-sided and multi-sided tests.

Single-sided tests are conducted in a condensation chamber according to ISO 6270-1, an enclosed space with an atmosphere of 100% relative humidity at a temperature of 38 ± 2 °C. The side of the (nearly flat) specimens is exposed to the condensation phase, while the back of the panel/specimen is kept at standard laboratory conditions (23 °C and 50% RH).

Multi-sided condensation tests according to ISO 6270-2 are performed in a climate chamber at 40 °C and 95-100% RH, in which the specimens are placed. The exposure duration can vary from 24 hours to 1,000 or 2,000 hours, depending entirely on the specification. The standard also describes cyclic RH tests. If required, there is also the possibility of introducing gases.

Furthermore, the laboratory has several climate chambers in which the temperature and relative humidity can be set and/or varied as desired.
