I had a PC test done with my most recent oil analysis. Blackstone didn't elaborate on what the numbers mean when they sent the report, and I didn't see anything on their website.
Code:
Particle Count
ISO Code (2) 14/10 clean
NAS 1638 Class 0
ISO Code (3) 14/13/11
>= 2 micron 252
>= 5 micron 93
>= 10 micron 25
>= 15 micron 10
>= 25 micron 2
>= 50 micron 0
>= 100 micron 0
I did a search for NAS 1638 and found the following table, which helps a little bit:
and I found this table for ISO Code:
but what is the difference between ISO Code (2) and ISO Code (3)?
It makes sense that the goal is to have as few particles as possible in the oil, but other than that it's greek to me
