(OP)
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.

RE: Source of NAS 1638 Hyd Fluid Cleanliness

The equivalent ISO standard to NAS 1638 Class 6 is

ISO 4406 : Code 17/15/11.

RE: Source of NAS 1638 Hyd Fluid Cleanliness

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.
