They only call out ASTM 2659, that’s moisture meter guys. Here’s what it says: Although this floor is waterproof, from the top down, it is not to be used as a moisture barrier. The subfloor must be dry. Concrete moisture vapor emissions should not exceed 2.5% moisture content (ASTM F2659 method). Prior to installing flooring, remove dirt, paint, varnish, wax, oils, solvents, any foreign matter and contaminants from the subfloor. Do not use products containing petroleum, solvents or oils to prepare subfloors as they can cause staining and expansion of the new flooring.

It was an amazing and successful day with Steve Phillips and David Daniels teaching and certifying the very talented INSTALL flooring instructors of the Carpenters Union in Edison, New Jersey, on the use of the Tramex Meters, the Five-Point Concrete Moisture Test, and the Time-of-Install Three-Point Test.
