DIN 51562-1-1999 viscosity measurement. Viscometer measurement of dynamic viscosity with Ubbelohde - Part 1: Viscosity meter specification and measurement procedure "is a standard developed by the German Institute for Standardization, which specifies the method of measuring the kinematic viscosity of liquids using the U-Viscosity meter. The standard describes in detail the design requirements, instrument calibrating, measurement procedures and evaluation of results of the U-Viscosity meter for viscosity measurement of transparent liquids in the viscosity range of 0.360,000 mm/s. Measurement principles are based on the outflow time of liquids in capillary tubing, and viscosity is calculated by known constants. The purpose of this standard is to ensure the accuracy and repeatability of viscosity measurements, which are widely used in chemical, pharmaceutical and materials science fields.
