The classic test for inhibitor is to place the steel surface into immersion of water with the recommended level of inhibitor. Iit is a comparison test. YOu can put it at the temperature that you expect to experience in your field conditions. SSPC has a standard method for producing uncontaminated rusted steel panels. This method , Test Panel Preparation, Method NO. 1, Uncontaminated Rusted Steel, can be used for your comparison, It was used to prepare Grade C rust on panels so that paints could be put on and the performance could be evaluated. In summary- they clean with solvent, dry blast to near white, and place in an ASTM G 85, Annex A.5 cyclic chamber, 1 hour wet and 1 hour dry. I would think that you would get comparison results in 24 hours. The total time is up to you. YOu should be comparing a known panel without any inhibitor to panels with the inhibitor.

I have yet to find a standard that covers this topic. I've read many of the ASTM humidity tests and most are for painted surfaces. I am trying to determine what temperature and RH to run a test for 24 hours. Does anyone know of such a standard test? Hello,
