Foaming of Lubricating Oils (manual) ASTM D 892, ASTM D 6082 sequence IV, ISO 6247, DIN 51566, IP 146, JIS K2518, BS 5092 (obs.) Product group(s): User group(s): Scope: Lubricant Testing Automotive, Engine Oil, Gear Oil, Jet Lube, Lube Oil, Lubricating Oil, Motor Vehicles, Power Plant, Transmission Fluid, Turbine Oil The tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. Tests at 150 C are determined according ASTM D 6082. For temperatures below 150 C according ASTM D 892.
