*Test Parameters:
1.?Viscosity
2.?Viscosity Index
3.?Flash Point
4.?Pour Point
5. Demulsification
6. Copper Corrosion
7. Acid Number
8. Foam Characteristics
9. Oxidation Characteristics
10. Water Separation
11.?Rust Prevention
12.?Cleanliness
13.?Water Content
*Oxidation Stability Test:?Turbine Oil Oxidation Stability Test?(TOST) is a valuable tool in order to indicate?oil?life for?lubricants?that are continuously exposed to gross water contaminations, high temperatures, and air entrainment in field service.
ASTM D943 is commonly referred to as Turbine Oil. The Oxidation Stability Test (TOST), is widely used in the lubrication industry to evaluate oxidation stability.
*Best Practices for Steam Turbine Lubrication:
?1.?Keep Oil Clean, Cool and Dry
2. Install High Capture Efficiency Breathers to your Oil Respective Oil Tanks
3. Monitor returning bearing oil temperature regularly
4. Maintain proper alignment
5.?Inspect for signs of foaming and /or Air Entrainment
6.?Install primary (return line) and secondary sampling points
7.?Perform regular oil analysis
8.?Routinely inspect sight glasses for level, foam, and water
9.?Keep tank headspace dry using?blowers, condensers, or instrument air
10.?Drain accumulated water regularly
11.?Use offline fluid conditioning for precision contamination control
12.?Regularly inspect for varnish, especially in gas turbines
13.?Protect against water and or detergent ingress during wash-down
14.?Inspect bulk delivery of new oil before acceptance?

From a standpoint of condition monitoring of the oil in servcie, May I respectfully suggest this list could be upgraded and updated, to include MPC (ASTM D7843), as varnish is prevalent matter, and RULER, ASTM D6971, as TOST isn't truly practical nor best suited?
