Aerospace series. Hydraulic filter elements. Test methods - Filtration efficiency and retention capacity1 Scope This part of ISO 14085 describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element per ISO 14085 1, or separately. Since the filtration efficiency of a filter element can change during its service life as it is clogging, this test method specifies its continuous
