标准编号：ISO 23369:2021

中文名称：液压传动 在循环流动条件下评价滤芯过滤性能的多道方法

英文名称：Hydraulic fluid power — Multi-pass method of evaluating filtration performance of a filter element under cyclic flow conditions

发布日期：2021-06

标准范围

 This document specifies:
a) A multi-pass filtration performance test under cyclic flow conditions with continu injection for hydraulic fluid power filter elements.
b) A procedure for determining the contaminant capacity, particulate removal pressure characteristics.
c) A test currently applicable to hydraulic fluid power filter elements that exhibit an ratio greater than or equal to 75 for particle sizes ≤25 µm(c), and a final test gravimetric level of less than 200 mg/L. It is necessary to determine by validation rates and the lower particle size limit that can be used in test facilities.
 d) A test using ISO 12103-1 A3 medium test dust contaminant and a test fluid.
