Testing and Test Interruptions
Specialist 1 – In the past, if I have been present when the power failure occurs, and it is down for more than 5 minutes or so, I will remove the power from all test samples and open the chamber door. I do not have a UPS on the chamber, as it would be very expensive to get the necessary power feed. When the power returns, I check to see what the last set of data was. I ramp up the chamber to test conditions, wait an hour or so, and start measuring [again].
When the samples return to what they were before the test, with say ¼logΩ, then the test clock continues. Then I make note of it in the final report. During the post-test visuals, I look closely for water spots or other signs of condensation.
Assuming I am not present for example during the night, it is better to start with a new set of coupons and re-run the test.
I have always found it less costly to re-run the test, rather than trying to interpret questionable data to a client.
