This Standard specifies the determination of filterability of lubricating oil taking mineral oil as base oil, especially the method for evaluating the filterability of hydraulic oil in hydraulic system. This Standard applies to oils with viscosity grade being not higher than 100 according to the viscosity classification provisions of GB/T 3141. This Standard does not apply to liquids taking other materials as base material, such as fire resistant fluid, because there may be compatibility problems between it and the filtration membrane used in this Standard. This Standard does not apply to hydraulic oil with special properties, because it may contain insolvable additives or partially dissolved additives or special macromolecular substances.
