ansi source of nas 1638 hyd fl
does anyone know where i can get a copy of national aeronautical society hydraulic fluid cleanliness standards nas 1638 class 6 and is there any table of iso/ansi /sae equivalents.
the equivalent iso standard to nas 1638 class 6 is
iso 4406 : code 17/15/11.
a very old post i know but i've just been looking for a similar thing and found this document, the fluid cleanliness standards gives a good list of equivalents.
