Determination of Particulate Contamination in Hydraulic Fluid 

ISO 4406 defines the method used for coding the contamination and specifies that the sample must be analyzed according to ISO 4407. The method required is particulate counting by optical microscopy and the use of a motorized stage is highly recommended. In these standards, the differentiation between “regular” particulates and fibres is required. Clemex PSFilter is a system fully compliant with ISO 4406 & 4407 for hydraulic Fluid Cleanliness.
