ASTM WK65113

    New Test Method for Standard Test Method for Wet Filterability of Lubricants and Hydraulic Fluids by Mass Flow Technique

    (What is a Work Item?)

    Developed by Subcommittee: D02.N0 | Committee D02 | Contact Staff Manager



    WK65113

    1. Scope

    This test method covers determination of the wet filterability of lubricants and hydraulic fluids based upon mass flow rate measurements through a 0.8 m membrane after ageing of the fluid in the presence of water. The procedure applies to lubricants and hydraulic fluids that are formulated with Group I, II, III, IV and V base stocks. Products formulated with water and base stocks that are heavier than water are out of scope.


    Keywords

    Filtration, filterability, filter blocking potential, water tolerance, laboratory filtration

    Rationale

    Filterability is an important property of hydraulic fluids and lubricants. There is a need for a standard method for measuring this property. ASTM does not currently have a mass-flow rate based filterability procedure.

    The title and scope are in draft form and are under development within this ASTM Committee.
