标准摘要
[中文适用范围]： 本国际标准规定了在极低温度下，经过至少 20 小时的冷浸泡时间后，通过测量一定体积液体流动的时间来测定透明和不透明矿物绝缘油的运动粘度的程序。在重力作用下通过校准的玻璃毛细管粘度计。它在所有温度下都适用于粘度高达 20000 mm × s 的牛顿和非牛顿液体。它特别适合测量寒冷气候、极低温度 (-40 ℃) 或云点温度和倾点温度之间的温度（通常为 -20 ℃）的液体运动粘度，在这些温度下，某些液体可能会形成液体在冷浸条件下具有出乎意料的高粘度。 [外文原描述]： 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 throught a calibrated glass capillary viscometer. Applies at all temperatures to both Newtonian and non-Newtonian liquids having viscosities of up to 20 000 mm2/s.
