I recently saw some reports that one of our plants recieved from an outside lab. There was a line on the report that listed a "PQ index". I'm not quite sure how to interpret this number and it's magnitude. Does anyone know about this and how it compares to using other data (ex. particle counts).
To give a little more background, most of our plants use an in-house lab that does TAN, Moisture, Spec., FTIR, Viscosity, Particle Counts, and ferrography. I'm used to seeing this data already...I'm just not sure how useful this PQ index is with regards to other information available.
Thanks for any insight you can provide.
