ISO CODES:
ISO = International Organization for
Standardization.
Contaminant code for expressing the
level of particulate contaminant in fluids and specifying levels of cleanliness. It has
been approved by the Society Of Automotive Engineers. An ISO cleanliness code is assigned
by citing the two ISO ranges for the number of particles greater than 5 and 15 micron per
milliliter.
Example: If
the number of particles in a fluid sample larger than 5 micron and 15 micron are found to
be 1,960 per ml and 240 per ml respectively, it has an ISO code of 18/15.
