BS ISO 13357-1:2017 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 viscosity grade (VG) 100, as defined in ISO 3448. Within the range described,
the filterability as defined is not dependent on the viscosity of the oil. The procedure is not suitable for
some hydraulic oils on which specific properties have been conferred by the use of insoluble/partially
soluble additives, or by particularly large molecular species.
NOTE Filterability is a prime requirement for lubricating oils used in hydraulic systems because of the fine
filters used in this application.
This document defines a method for assessing the filterability of oils in the presence of contaminating
water. It is noted that some oils will exhibit poorer filterability characteristics in these conditions.
ISO 13357-2[1] is used to investigate the filterability of an oil which is used in applications where
the presence of water in the oil is unlikely. An oil which has good filterability in the presence of
contaminating water will not necessarily have equally good filterability in dry conditions. An oil having
good filterability only when wet is unlikely to be generally acceptable.
