which utilizes and circulates the turbine generator lubricating
oil and furnishes pressurized oil for control and seal functions.

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.

2. Referenced Documents

2.1 ISO Standard:
ISO 4572 Hydraulic fluid power-fillers-multi-pass method
for evaluating filtration performance2

3. Significance and Use

3.1 This practice establishes minimum recommended design practices for gas turbine generator lubricating oil systems
to ensure that:

3.1.1 Lubrication, control, and seal functions will be performed satisfactorily by the oil mutually acceptable to the
parties concerned.

3.1.2 Installation, cleaning, and flushing will be facilitated
