RE: Calcium Carbide testing and Silicates
IMHO the 2420 test will always accumulate RH inside the hood. The standard attempts to address it by stipulating the amount of acceptable drift in your reading once you've waited the 72h. If you're testing the performance of a mitigation product, it's only useful if you've tested the bare slab prior to the application, but as JD says, it at least evidences the fact that vapour is still emitting, albeit a little innacurately.

I love that geyser pic! Scott Tarr and Peter Craig have been dining out on that one for yonks... Smile
