Aerospace - Procedure for the Determination of Particulate Contamination in Hydraulic Fluids By the Control Filter Gravimetric Procedure ARP785

This SAE Aerospace Recommended Practice (ARP) describes a gravimetric method for the determination of particulate contaminant in hydraulic fluids by the control filter technique. With this method detectable contamination levels down to 0.2 mg per sample can be obtained with a standard deviation of ±0.1 mg.
