HYDRAULIC FLUID POWER - FLUID CONTAMINATION - DETERMINATION OF PARTICULATE CONTAMINATION BY THE COUNTING METHOD USING AN OPTICAL MICROSCOPE
出版：International Organization for Standardization
专家解读视频
Describes 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 also includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems.
