GB/T 22235-2008 "Determination of liquid viscosity" specifies the method for measuring liquid viscosity. The five methods listed in the standard are all suitable for newtonian fluids in principle, and the swirl/spin Viscosity meter method can also be used for non-newtonian fluids. These methods include a swirl/spin Viscosity meter for measuring dynamic viscosity by measuring torque on swirl/spin parts, a capillary tubing Viscosity meter for calculating kinematic viscosity by measuring liquid flow time in capillary tubing, and a falling ball viscometer for measuring dynamic viscosity by measuring pellet sedimentation time in liquid. This standard provides a unified and standardized technical basis for liquid viscosity measurement in various fields such as hazardous chemicals management, Petrochemicals, product quality control, etc.
