Hydraulic fluid power. Fluid contamination. Determination of particulate contamination by the counting method using an optical microscope1 Scope This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems. Particle sizes 2 m can be sized and counted by this method, but the
