Full Flow Lubricating Oil Filters Multipass Method for Evaluating Filtration Performance(Cancelled Jun 2002, Superseded by ISO 4548-12) J1858_200206

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.
