Water separability and demulsibility per ASTM D1401 and ISO 6614 — the anti-wear hydraulic oil's ability to separate from water is tested to ensure the oil can be dehydrated and to prevent the formation of stable emulsions that would degrade lubrication performance.

Anti-Wear and Extreme Pressure Performance Testing for Hydraulic Oils

Four-ball wear test per ASTM D4172 and DIN 51350-3 — the anti-wear hydraulic oil is tested in a four-ball tribometer where a rotating ball is pressed against three stationary balls, and the wear scar diameter is measured to quantify the oil's ability to protect metal surfaces under boundary lubrication conditions.
Four-ball extreme pressure test per ASTM D2783 and DIN 51350-2 — the load-carrying capacity and the weld point of the hydraulic oil are determined to verify the anti-wear additive package provides adequate protection against scuffing and seizure under high-load conditions.
FZG gear scuffing test per ASTM D5182 and ISO 14635-1 — the anti-wear hydraulic oil is tested in a gear test rig and the failure load stage is determined, providing the most representative assessment of the oil's anti-wear performance in hydraulic pumps and motors with heavily loaded gear contacts.
Vickers vane pump wear test per ASTM D2882 and ISO 20763 — the hydraulic oil is circulated through a standard vane pump under controlled pressure and temperature for a defined duration, and the wear of the vanes and ring is measured to verify the oil provides adequate protection in real hydraulic pump service.
Fretting wear and oscillating friction test per ASTM D7594 — the anti-wear hydraulic oil's resistance to fretting wear under small-amplitude oscillating motion is evaluated, ensuring protection of hydraulic cylinder rods, bearings, and tight-clearance components.
Copper strip corrosion test per ASTM D130 and ISO 2160 — the anti-wear hydraulic oil is tested for its corrosivity to copper and copper alloys, verifying the additive package does not attack yellow metals in pumps, valves, and heat exchangers.

Oxidation Stability and Thermal Degradation Testing for Anti-Wear Hydraulic Oil

Rotating pressure vessel oxidation test per ASTM D2272 and ISO 6886 — the anti-wear hydraulic oil is aged under oxygen pressure at elevated temperature, and the time to a defined pressure drop is measured to determine the oxidation stability and the remaining useful life of the oil.
Thermal stability and coking tendency per ASTM D2070 and internal protocols — the hydraulic oil is exposed to high temperatures on a hot surface and the formation of deposits, sludge, and varnish is measured to predict the oil's resistance to thermal degradation in high-temperature hydraulic systems.
Total acid number and acid number increase after aging per ASTM D664 and ISO 6618 — the acidity of the fresh and aged anti-wear hydraulic oil is measured by potentiometric titration, and the increase in acid number indicates the degree of oxidation and the depletion of the anti-wear additive package.
Long-term thermal oxidation test per ASTM D943 and ISO 4263-1 — the hydraulic oil is aged in the presence of water, oxygen, and metal catalysts at elevated temperature, and the time to reach a defined acid number is measured to predict the oil's service life under continuous operation.
