This standard specifies the maintenance and supervision of mineral turbine oil used for lubrication and speed regulation of turbine, water turbine and gas turbine systems in power plants. It may also be referred to for maintenance and supervision of mineral turbine oil used for auxiliary equipment such as phase modifier and feed pump.
This standard is applicable to the maintenance and supervision of mineral turbine oil used for lubrication and speed regulation of turbine, water turbine and gas turbine systems in power plants.
This standard is not applicable to a variety of non-mineral synthetic fluids used for lubrication and speed regulation of turbine.
