ABSTRACT:
The method described comprises the steps of, firstly, a water content of from 3 to 20 wt %, based on the water-containing fluid, being set in the hydraulic fluid to be tested, followed by the water-containing fluid being mixed with at least 1 part by volume of tetrahydrofuran or monoethylene glycol dimethyl ether per part by volume of water-containing fluid, whereupon the formation or nonformation of a precipitate is ascertained.
