Part 3, Contamination Leveland ISO Cleanliness

Wear Particle Atlas CD-ROM

The Contamination Level and ISO Cleanliness feature is one of four mainfeatures of the Wear Particle Atlas CD-ROM. It provides a useful referenceto estimate lubricant cleanliness. The cleanliness reference in Atlas consistsof 10 contamination levels corresponding to the sequential ISO Cleanlinesslevels from ISO 13/10 up to ISO 24/21. An example of ISO cleanliness anda corresponding contaminant level page is provided below:

 

Contamination Levels and Corresponding ISO Clenaliness

 Contamination Level

ISO Cleanliness

Level 1

ISO 13/10

Level 2

ISO 15/12

Level 3

ISO 16/13

Level 4

ISO 17/14

Level 5

ISO 18/15

Level 6

ISO 19/16

Level 7

ISO 20/17

Level 8

ISO 21/18

Level 9

ISO 22/10

Level 10

ISO 24/21

 

 

Each level contains 4 representative solid particle images grabbed fromdifferent areas of the filtergram with varied magnifications. This componentcan be used to correlate machine wear with lubricant dust contaminationand to estimate the contamination levels of some very dirty, very viscous,or water contaminated oil samples. These types of samples are usually unavailableor inconvenient for analysis by automatic particle counting.

Thank you for visiting the "Oil Cleanliness Determiantions"feature of the Wear Particle Atlas CD-ROM. Additional features can be reviewedby returning to the Wear Particle Atlas CD-ROM FeturesIndex.
