Saline chamber test interrupted...may I continue?
Good morning.
I'm performing a 96 hrs saline chamber test for a stainless steel part but due to maintenance issues, it was interrupted for a 3 hrs period after 48 hrs ... may I continue with remaining 48 hrs or should I start again? I'm using ASTM B117

Dear Jesus Duran,
3 Hours of break is not advisable.
Better you start the test with new parts from starting.

Jesus, ASTM B117 is pretty clear that the test is supposed to be uninterrupted except to examine, add or remove samples daily. I would start it over.

As the others advised, I would restart the test, preferably with freshly processed specimens. After three hours, salt solution will likely have dried on your test surface, negatively influencing test results.
Interruptions that are short in duration - say opening the chamber to inspect specimen condition - are ok, as long as they are limited to a few minutes per occasion (keep interruptions to a minimum). B117 requires that we log the date/time/duration of these interruptions. You should also adjust the test's end time to compensate for the stoppage.
