The application of this test shall be stated in the specification of the DUT. Failure mode is electrical malfunction caused by low temperature, e.

This happens when driving on wet kso during the winter.

Failure modes are cracking of materials or seal failures caused by ageing and different temperature expansion coefficients. Failure mode is electrical malfunction caused by moisture, e. General [1] ISO International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

This test generates corrosion similar to reality.
