The code is constructed from the
combination of three scale numbers
selected from the following table.
The
first
scale number represents
the number of particles in a mil-
lilitre sample of the fluid that are
larger than 4 µm(c).
The
second
number represents the
number of particles larger than 6
µm(c).
The
third
represents the number of
particles that are larger than 14 µm(c).
