Definition acc. to SAE
Particle count (absolute) larger than a defined particle size
Example: Cleanliness class acc. to AS 4059=6
The maximum permissible particle count in the individual size ranges is bold-
faced in the table on page 126.
Cleanliness class to AS 4059= 6B
Size B particles may not exceed the maximum number indicated for code 6:
6 B = max. 19,500 particles > 5 µm in size
Specifying a cleanliness code for each particle size
Example: Cleanliness class to AS 4059= 7 B / 6 C / 5 D
Specifying highest measured cleanliness class
Example: Cleanliness class acc. to AS 4059= 6 B – F
The 6 B – F specification requires 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.
