The damp heat test has test levels as +40C / 95%Rh and the duration is 21 days with the equipment POWERED OFF during the test. Question: After 21 days, a functional test shall be carried out. Shall this test be carried out at the end of the test med damp heat condition or shall the equipment first be brougth back to normal conditioning and the functional tested. Please EN54-2 experts, looking forward to some comments on this issue.
