适用范围:This International Standard specifies a procedure for the determination of the kinematic viscosity of mineral insulating oils, both transparent and opaque, at very low temperatures, after a cold soaking period of at least 20 h, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer.
It is applicable at all temperatures to both Newtonian and non-Newtonian liquids having viscosities of up to 20 000 mm
