Summary This standard specifies the transparent and opaque mineral insulating oil at least 20h after experiencing a certain constant temperature cold soak time, a certain volume of the sample was measured under the action of gravity through a capillary viscometer by the test of time to measure the temperature Movement viscosity method. 1. 2 standard applies at a constant temperature measuring kinematic viscosity of not more than 20 000 mm 2/s and Newtonian and non-Newtonian fluids, especially under low temperature conditions for the determination of kinematic viscosity liquids. At low temperature (-40 ~ C) or temperature between cloud point and pour point (typically -20��C), between some of the liquid in the full cooling may occur under conditions of high viscosity.
