FTM 3012 - Determination of Particulate Contamination in Aerospace Hydraulic Fluids (Laser Particle Counter)

We perform lubricants quality testing by FTM 3012 to measure particulate matter contamination in aerospace hydraulic fluids using a laser particle counter. This method describes the determination of particulate matter in aerospace hydraulic fluids with an automatic particle counter analyzer working on the light interrupt principle.  We use a Pacific Scientific Hiac Royco 8000A particle counter and ABS2 bottle sampler with an HRLD-400 sensor.  This sensor can detect particles from 2 to 400 μm in size.

This test method is commonly used for all types of military specification fluids.

Particle size is reported in ranges:

5-15 μm
16-25 μm
26-50 μm
51-100 μm
>100 μm
