This international standard specifies: - test equipment, test circuit, and a procedure for the evaluation of the water separation capabilities of a dehydrator; - a procedure for preparing test fluid; - a procedure for obtaining and analysing the test fluid samples; This international standard applies only to those dehydration units that can dry a hydraulic fluid to less than 20 % of the hydraulic fluid’s water saturation level at the test temperature. This international standard provides a test procedure that yields reproducible results for dehydrator water removal performance so that the performance of candidate units can be compared on the same basis. This procedure can be used to test the dehydrators’ capabilities on different types of hydraulic fluids at different conditions. However, comparison of performance can be made under the conditions defined in this standard. This test procedure can be used to assess a dehydrator’s performance with other hydraulic and lubricating fluids, but parts of the procedure might need changing to suit the hydraulic fluid’s characteristics. For example, the testing of hydraulic fluids with high water solubility (many synthetic and fire resistant fluids) needs higher concentrations of water at the start of the test, the testing of hydraulic fluids with zinc based additives needs modifications to the Karl Fischer analysis procedure.
