ASTM WK65113

    New 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

    1.1 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 American Petroleum Institute (API) Group I, II, III, IV, and certain V base stocks. Products formulated with water or base stocks that are heavier than water are out of scope. 1.2 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    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.
