Abstract (en)
[origin: DE19546856C1] The water content of the hydraulic fluid under test is first adjusted to between 3 and 20 wt % relative to the water-containing fluid and the water-containing fluid is then mixed with at least an equal volume of tetrahydrofurane or monoethylene glycol dimethyl ether. The formation or non-formation of precipitate is then determined.
