Steps 2) to 5) constitute one cycle, with each cycle lasting 24 hours, for a total of 10 cycles. Before the test begins, an initial inspection is conducted on the samples under test; once the initial inspection is completed, the power is cut to those samples. Intermediate tests are conducted near the end of the 5th and 10th cycles. The final test is conducted after the experiment is completed and normal atmospheric conditions are restored.
