WQTM 611  – Hydraulic Fluid Particulate Count

Most failures in hydraulic systems result from particulate contamination of hydraulic fluids.   Contamination may arise from internal/manufacturing  sources (fluid degradation, wear debris, rubber or welding debris) or external sources (dust, water vapor, contaminated fluid addition).   To keep systems running optimally, fluids should have low particulate levels.  This is a BASF test method to determine the size and numbers of particulates in hydraulic fluids.

The sample hydraulic fluid is filtered. The filter paper is placed under a microscope and examined for particles of various sizes.  The ISO Solid Particulate Code number of particles greater than 5 micrometers and particles greater than 15 micrometers are reported.
