A Comparison of NAS and ISO Cleanliness Codes. The NAS system was originally 18/16/13, 7, 32,, , , , 19/17/14, 8, 64, Particle Contamination – ISO And NAS Cleanliness Codes. Oil cleanliness is critical to 7, Minimum required cleanliness class for high pressure - servo valve . In general hydraulic systems should never exceed a NAS 7 class. The obtained ISO and NAS code is an indication of the cleanliness of the oil in the system.
