This standard establishes a multipass filtration performance test with continuous contaminant injection for lubricating oil filter elements. It also includes a procedure for determining the contaminant capacity, particulate removal characteristics, and pressure loss. It also includes a test currently applicable to lubricating oil filter elements which exhibit a 10 μm filtration ratio of less than 75 and a rated flow between 4 and 600 L/min. This standard provides a test procedure which yields reproducible test data for evaluating the filtration performance of a lubricating oil filter element.
