ISO/FDIS 16889, Hydraulic fluid power filters-Multi-pass method for evaluating filtration performance of a filter element

摘要

In hydraulic fluid power systems, one of the functions of the hydraulic fluid is to separate and lubricate the moving parts of components. The presence of solid particulate contamination produces wear, resulting in loss of efficiency, reduced component life and subsequent unreliability.A hydraulic filter is provided to control the number of particles circulating within the system to a level that is commensurate with the degree of sensitivity of the components to contaminant and the level of reliability required by the users.To enable the relative performance of filters to be compared so that the most appropriate filter can be selected, test procedures should be available. The performance characteristics of a filter are a function of the element (its medium and geometry) and the housing (its general configuration and seal design).
