Petroleum products. Determination of the filterability of lubricating oils - Procedure for oils in the presence of water1 Scope This document specifies a procedure for the evaluation of the filterability of lubricating oils, particularly those designed for hydraulic applications, in the presence of water. The procedure only applies to mineral based oils, since fluids manufactured from other materials (e. g. fire resistant fluids) may not be compatible with the specified test membranes. The range of application has been evaluated with oils of viscosity up to ISO
