通过指定的旋转粘度计测定牛顿或非牛顿试样的流动特性，该粘度计将允许对牛顿产物同时测量测定时的剪切速率，但对于非牛顿产物，可能测量测定时使用的各种表观剪切速率。

Flow properties of a newtonian or non-newtonian test portion are determined by means of a specified rotational viscometer, which will allow, for the newtonian products, the simultaneous measurements of the shear rate at which the determination is carried out, but for the non-newtonian products, possible measurement of various apparent rates of shear used for the determination.
