Hydraulic Fluids Industry Specifications C3 1 800 255 4417 www.castroldiesel.com/GPS Thermal Stability: Cincinnati Milacron This test evaluates whether an oil will cause a reaction to steel and copper components. Run for 168 hours at 135°C/275°F. Test Criteria P-68, P-69 HF-O and P-70 Viscosity change, (%), max 5 Neutralization number, (%), max ±50 Sludge (mg/100 ml), max 25 Copper wt loss (mg), max 100 10 Copper rod appearance5Report Iron rod appearance No discoloration 1000-h Sludge (ASTM D 4310) This test measures the build-up of sludge and increase of iron and copper particulate in the oil. Test CriteriaDenison HF-O HF-1 HF-2 TAN (mg KOH), max 1.0 .2 1.0 Insoluble Sludge, mg max 100 100 400 Total Cooper, mg max 200 - 200 Total Iron, mg max 50 - 100 TAN (ASTM D 974-07) Standard Test Method for Acid and Base Number by Color-Indicator Titration Importance of Wear and Load Tests Load performance and wear protection are crucial components when selecting a hydraulic fluid. Hydraulic fluids are designed to handle important shock loads and other various types of loads during operation. The ability to prevent metal to metal contact also results in lowering component wear, such as in hydraulic pumps. Proper viscosities and excellent anti-wear additives play a pivotal in protecting against wear. FIELD TESTED. FLEET TRUSTED. GPS-2014-1 © 2014 Wakefield Canada Inc.
