ISO Explanation
The ISO 4406:1999 standard currently
reflects the number of particles greater
than 4 microns, 6 microns and 14 microns.
The 4 and 6 micron ranges are used to give
an indication of the "silting" condition of a
fluid, while the 14 micron range reflects the
presence of larger "wear catalysts".

ISO CODE
15 / 13 / 09
The ISO classification shown below is
15/13/09. These values are range numbers
that correlate to the ISO 4406 chart
(Figure 6).
If your IQ-200 reports to ISO 4406:1987 modified,
the data would be broken down as follows:
Particles
> 4(c) microns
Particles
> 6(c) microns
Particles
> 14(c) microns
