GB/T 42653-2023 "Test Method for High-Temperature Viscosity of Glass" specifies the methods for testing the high-temperature viscosity of glass melts. Using a high-temperature rotational viscometer or an extensional viscometer, it measures the variation of viscosity with temperature for glass in its molten state (typically ranging from 10^0.5 to 10^13 dPa·s), providing critical data for glass melting and forming processes.
