Assessment of the Low Temperature Brookfield Viscosity of Lubricants by a New Liquid Bath Method 780941

Presently, the different methods available to measure the viscosity of fluids at low temperature with the Brookfield viscometer do not give entire satisfaction because of their low precision. A working group set up by the Technical Committee “Transmission Lubricants” (T.L.T.C.) of Groupement Français de Coordination (G.F.C.), member of C.E.C.*, ran different tests which led to the proposal of a new method. This new procedure for measuring the Brookfield viscosities includes the following improvements :
  • shortened test duration
  • better precision,
and was adopted by C.E.C. as tentative method under the number CEC L18-T76.
