ASTM WK41873

    Work Item: ASTM WK41873 - Revision of D4684 - 12 Standard Test Method for Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature

    (What is a Work Item?)

    Active Standard: D4684 - 12

    Developed by Subcommittee: D02.07 | Committee D02 | Contact Staff Manager



    1. Rationale

    1) Revise DCT requirements to include new E20 DCT guide and related documents. 2) Revise equipment description for temperature control to be performance orientated rather than technique specific 3) Revise Shear Stress and Shear Rate definitions to use standard rheology symbols. 4) Modify wording of procedural section to provide better consistency between the four methods using this device. 5) Move materials information from definitions to material section.
