To me I'd say the average person placing an ASTM kit dosent have the ability or liability coverage to interpret every slab and test. That is why we have ASTM's F06 committee.  To set a standard to use.

People are getting better, in my opinion, but interpretation of results will always be an issue.  My thought is that we can throw three or four more tests on here, but how far do we go to try and mitigate risk by 100%?  The more you throw on, the less incrementally you gain, and the more cumbersome the process.  What about doing core samples of the concrete to verify an intact vapor retarder?  By itself, insitu RH testing gives us the best and highest probability chance of avoiding flooring failures.These opinions and $4.00 will get me a good cup of coffee     Jason
