The following terms and definitions apply to this standard. 3.1
Viscosity
Also known as viscosity or internal friction, is a property of a fluid that hinders its relative motion, that is, the property of a liquid substance under stress when it is deformed. It depends on the rate of deformation, and stress can also be considered as the cause of the deformation rate. The relationship between tangential force and tangential velocity D is shown in the following formula:
will be defined as dynamic viscosity.
For Newtonian fluids, the viscosity is a constant at all tangential velocities, and its magnitude is determined by pressure and temperature. For non-Newtonian fluids, the viscosity changes with the change of tangential velocity. If the viscosity is measured by a capillary viscometer without applying external pressure, the measured value is the ratio of dynamic viscosity to density, which is kinematic viscosity. The SI unit of dynamic viscosity is Pa·s, and the more suitable unit in actual use is mPa·s. The conversion relationship between them is: 1 mPa·s= 10* Pa.s
The S unit of kinematic viscosity is m*/s1mm/s=10-m/s4Required information
Required information is as follows:
a) Density (for falling ball viscometer method); b) Melting point/melting temperature range of amorphous materials; c) Boiling point/boiling temperature range.

Viscosity can be measured according to the following three measurement principles: the liquid to be measured flows through a capillary tube - capillary viscometer or flow cup; a)
Liquid shears between concentric cylinders, conical plates and parallel plates - rotational viscometer method; c) Dynamic viscosity is measured by the movement of a small ball in a cylinder vertically or obliquely filled with liquid - Hopple falling ball viscometer, pulling ball viscometer, etc.
When using the Hopple viscometer, the density should be known first to calculate the dynamic viscosity. 7 Test steps
