英文名称：Hydraulic fluid power — Filters — Multi-pass method for evaluating filtration performance of a filter element
发布日期：2022-01
标准范围
This document describes the following:
— a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements;
NOTE 1 For the background interlaboratory study used to verify the test methodology, see Annex D. — a procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics;
— a test currently applicable to hydraulic fluid power filter elements that exhibit an average filtration ratio greater than or equal to 75 for particle sizes ≥ 25 µm(c), and a final reservoir gravimetric level of less than 200 mg/L;
