标准简介: | ISO 4407-2002 液压传动.液压液污染.用光学显微镜计数法测定粒状物污染 ISO4407-2002 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 greater than or equal to 2 micrometres can be sized and counted by this method but the resolution and accuracy of the results will depend upon the optical system used and the capabilities of the operator.All hydraulic fluids with a wide range of contamination levels can be analysed according to this International Standard. However the counting uncertainty at the larger particle sizes increases if the volume filtered is reduced to allow smaller sized particles to be counted where a fine precipitate or a high particle concentration is present. 标准压缩包解压密码:www.51zbz.com |
