标准范围

该方法允许连续测量粘度和各种剪切应力下的测量。粘度由流场系数、扭矩和旋转频率决定。描述了两种类型的旋转粘度计:带可调旋转坩埚的Couette型粘度计和带静止坩埚和柱塞旋转的Searle型粘度计。规定了程序，并描述了带有计算公式（附录A）和典型旋转粘度计（附录B）的典型流场示例。

This method allows continuous measurements viscosity and measurements under various shearing stresses. The viscosity is determined by the flow field coefficient, the torque and the rotational frequency. Two types of rotation viscometers are described: viscometer of the Couette type with adjustable revolving crucible and viscometer of Searle type with the crucibel at rest and the plunger revolving. The procedure is specified and typical examples of flow field with formules for calculating (annex A) and a typical rotation viscometer (annex B) are described.
