This standard specifies the product variety and labeling, requirements, test methods, inspection rules and marking, packaging, transportation and storage of lubricating oils for turbines.
This standard is applicable to lubricating oils for turbines used in turbine lubricating and control systems of power plants, including steam turbines, water turbines, gas turbines and gas-steam combined cycle turbines with common lubricating systems, which are made by refined mineral oil or synthetic raw materials as base oil and adding various additives such as antioxidants, corrosion inhibitors, and anti-wear agents. It is also applicable to turbine oil used in lubricating systems of turbine drive devices for other industrial or marine applications.
This standard is not applicable to anti-combustion turbine oil and water turbine lubricant with special requirements.
