1 Scope
This standard specifies the quality criteria of mineral turbine oils used for lubrication and speed regulation of turbine, water turbine and gas turbine systems in power plants.
This standard is applicable to the quality supervision of mineral turbine oils used for lubrication and speed regulation of turbine, water turbine and gas turbine systems in power plants. It may also be referred to for the quality criteria of mineral turbine oils used for phase modifiers, water pumps and other power plant equipment.
This standard is not applicable to all kinds of synthetic liquid used for lubrication and speed regulation of turbine.
