ASTM F312 – Microscopic Sizing and Counting Particles of Aerospace Fluids on Membrane Filters

Aerospace turbine and hydraulic fluids are essential to proper functioning of an aircraft.  Particles in these fluids may clog filters and cause wear of system components.  When significant numbers of particles are detected, it is may be desirable to visually examine the particles to aid in determining the source.  This method determines the number and size of particles in aerospace fluids using visual microscopy.

The sample is filtered and the filter paper is examined under a microscope.  There are two reporting options for this test.  Method A reports the number of particles in size categories based on their area and Method B reports the number of particles in size categories based on their longest dimension.  There are 5 size categories:  5µ to 15µ, 16µ to 25µ, 26µ to 50µ, 51µ to 100µ and over 100µ.  When requesting this test, please specify Method A or Method B.
