Cleanliness analysis as per ISO 4406&4407

ISO 4406 &4407 define the methods to determine the particulate contamination in hydraulic fluid power systems by optical microscope. In this report, a membrane filter sample was submitted for particulate contamination determination and identification according to ISO 4406&4407.

Demonstrate the ability of Clemex Contaminants to automatically identify, measure and classify particles with respect to ISO 4406&4407. The technical report is linked at the bottom of this page (click the Download PDF link below).


The whole area of the filter was scanned during the analysis. The sizes of different particles were measured and classified based on ISO 4406&4407.  Final results can be printed directly from Clemex Contaminants. Raw data can be exported in Excel format.
