ASTM D2070 Thermal Stability of Hydraulic Oils
Cincinnati Milacron Thermal Stability – This test is intended to measure the thermal stability of hydraulic oils. In the ASTM D2070 Method ($225.00 per run), copper and steel rods are placed together in the oil which is heated to 135°C for one week. The visual condition of the metal specimens is reported according to the Cincinnati Milacron color chart, and the total sludge in mg/100 ml oil is reported. In the PLTL-86 A version ($495.00 per run, 135°C for one week) additional data is reported including Viscosity Change, Acid Number Change, Sediment Weight, Sludge Deposit Weight, and Visual Descriptions. In the PLTL-86 B version ($400.00 per run,101°C for either 24 or 72 hours) additional data is reported including Viscosity Change, Acid Number Change, Sediment Observation, and Visual Descriptions. Please be sure to select the Method you need.
