Acid Demand Value (ADV) Test Kit Simpson Technologies
The Acid Demand Value (ADV) Test measures the amount of basic material present in the sand that is soluble in a dilute acid solution. Since the reaction which cures the resin in many chemical binder systems is acid alyzed, and since the acid is very mild, the presence of the basic material which can neutralize this weak acid will retard the curing reaction.

Acid/Base Demand Test [Archive] The PoolForum
Jul 23, 2006 · Evan (waterbear), The acid and base demand tests actually do not make any assumptions about the alkalinity which is why such tests are in fact reasonable. The tests simply add real acid or base to your existing pH measurement sample and you note the color change. The tables simply convert the number of drops into the amount of acid or base needed in scaledup pool volumes.
