(Practice)Standard Practice for In-Service Monitoring of Lubricating Oil for Auxiliary Power Plant Equipment
Standard Practice for In-Service Monitoring of Lubricating Oil for Auxiliary Power Plant Equipment
SIGNIFICANCE AND USE
This practice is intended to help users, particularly power plant operators, maintain effective control over their mineral lubricating oils and lubrication monitoring program. This practice may be used to perform oil changes based on oil condition and test results rather than on the basis of service time or calendar time. It is intended to save operating and maintenance expenses.
This practice is also intended to help users monitor the condition of mineral lubricating oils and guard against excessive component wear, oil degradation, or contamination, thereby minimizing the potential of catastrophic machine problems that are more likely to occur in the absence of such an oil condition monitoring program.
This practice does not necessarily reference all of the current oil testing technologies and is not meant to preclude the use of alternative instrumentation or test methods which provide meaningful or trendable test data, or both. Some oil testing devices and sensors (typically used for screening oils which will be tested according to standard methods) provide trendable indicators which correlate to water, particulates, and other contaminants but do not directly measure these.
This practice is intended for mineral type of oil products, and not for synthetic type of products, with the exception of phosphate esters fluids used typically in power plant control systems.
SCOPE
1.1 This practice covers the requirements for the effective monitoring of mineral oil and phosphate ester fluid lubricating oils in service auxiliary (non-turbine) equipment used for power generation. Auxiliary equipment covered includes gears, hydraulic systems, diesel engines, pumps, compressors, and electrohydraulic control (EHC) systems. It includes sampling and testing schedules and recommended action steps, as well as information on how oils degrade.
Note 1—Other types of synthetic lubricants are sometimes used but are not addressed in this practice because they represent only a small fraction of the fluids in use. Users of these fluids should consult the manufacturer to determine recommended monitoring practices.
1.2 This practice does not cover the monitoring of lubricating oil for steam and gas turbines. Rather, it is intended to complement Practice D4378.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.

INTRODUCTION
A more systematic approach to monitoring auxiliary power plant equipment can help to minimize
the high cost of oil changes and unplanned shutdowns. These avoided costs must be balanced against
the cost of sampling and laboratory testing.
This practice is designed to help the user plan and implement a meaningful, cost-effective program
of sampling and testing of oils in use. Also covered are some important aspects of interpretation of
results and suggested action steps so as to maximize service life of the oil and equipment.
