ASTM WK41875

    Revision of D6821 - 12 Standard Test Method for Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer

    (What is a Work Item?)

    Active Standard: D6821 - 14

    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.
