I didn't find standard which concerning about these two types of oil. But I recommend you to set the test and limit as well as follow:
Refrigeration Compressor Oil.
- Kinematic Viscosity@40 degree C (cSt, Max +10% and Min -40%)
- TAN (mg KOH/g, max +0.3 from starting point)
- Fe, Cu, Cr, Al, Pi (Max 50 ppm)
- Oxidation FTIR (Max 0.3 Abs)
- Water Content (Max 0.05%)
- Do oil replacement when reach 5 years or 2 Turn Around cycles.
Heat Transfer Oil
- Kinematic Viscosity@40 degree C (cSt, Max +10% and Min -20%)
- TAN (mg KOH/g, max +0.3 from starting point)
- Fe, Cu, Cr, Al, Pi (Max 50 ppm)
- Pentane Insoluble (Max 0.3%)
- Flash Point COC (Min, 180 degree C)
- Water Content (Max 0.05%)
- For NEW OIL, you may add: Conradson Carbon Residue (CCR) to check the tendency of the oil to be converted into carbon. (Max 1%)
- Do oil replacement when reach 10 years.
