Should you still opt for water as the test medium, imho: you might
need those corrosion inhibitor and probably biocide if it is from
natural sources. Using vacuum pumps would help a lot in drying
vessels or pipelines.
Else, you may opt for methanol as a test medium. Which i knew itwas
also being used in some cases, but i have no experienced on that.
