Icing Test – Extreme Cold Endurance Testing Solutions

When icing equipment, the effect due to the expansion of water in extreme cold conditions is used to test the endurance or resistance in case of icing.

The devices are iced either under normal atmosphere (simulation of e.g. rain in cold conditions) or under low atmosphere, or cyclically, to simulate a "breathing" of the test specimen with different testing solutions. The icing thicknesses depend on the target to be achieved. In this way, layer thicknesses of several centimeters can be built up, which can damage housings if necessary, while cyclic icing in the aviation sector simulates the passage of a cloud, which cyclically forms a frost with small layer thicknesses.
