ASTM D4248-98(2003)

The purpose of this guide for turbine generator oil systems is to ensure that:

3.1.1 Lubrication, control, and sealing will be performed satisfactorily by the oil in a manner mutually acceptable to the parties concerned.

3.1.2 Installation, cleaning, and flushing will be facilitated.

3.1.3 Satisfactory system cleanliness can be maintained.

3.1.4 Safe practices are observed.

1.1 This practice is applicable to steam turbine-generator units and provides recommended practices for the design of the oil system.

1.1.1 The oil system is defined as that assembly which uses and circulates the turbine-generator lubricating oil. The oil system generally includes high pressure, bearing, control, generator seal, and drain systems. The system may also include the supply and return lines for a boiler feed pump and hydraulic coupling.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
