Definition acc. to SAE
Particle count (absolute) larger than a defined particle size
Example: Cleanliness class according to AS 4059= 6
The maximum permissible number of particles in the individual size ranges is shown
in the table in bold.
Cleanliness class according to AS 4059= 6 B
Size B particles may not exceed the maximum number shown for class 6
6 B = max. 19,500 particles size > 5 µm
Specifying a cleanliness class for each particle size
Exa
mple: Cleanliness class according to AS 4059=7 B / 6 C / 5 D
Cleanliness class Particle count / 100 ml
Size B ( > 5 µm / > 6 µm
(c)
) 38,900
Size C ( >15 µm / > 14 µm
(c)
) 3460
Size D ( >25 µm / > 21 µm
(c)
) 306
Specify highest measured cleanliness class
Exa
mple: Cleanliness class according to AS 4059= 6 B – F
"6 B – F" specifies a particle count in size ranges B – F. The respective particle
concentration of cleanliness class 6 may not be exceeded in any of these ranges.
