GB/T 42414-2023 specifies the method for determining the viscosity of glass melts using a rotational viscometer (typically a high-temperature platinum-rhodium alloy rotor system). This method covers a wide viscosity range (e.g., 10^0.5 to 10^13 dPa·s) and is used to plot the viscosity-temperature curve of glass, serving as a fundamental basis for the design of glass melting, forming, and annealing processes.
