Scope

This document specifies the method of measuring the apparent viscosity of liquid resins using a single-cylinder rotational viscometer.
The viscosity measurement range of this method is 0.02 Pa·s to 60,000 Pa·s.
This document is applicable to Newtonian fluids and non-Newtonian fluids, and the apparent viscosity of the tested liquid depends on the velocity gradient during the measurement process.
