GB/T 21882-2008 "Liquid dyes - Determination of the viscosity"

This standard specifies the method for determining the viscosity of liquid dyestuff, which is suitable for viscosity testing of various types of liquid dyestuff. Viscosity is an important index to characterize friction in fluids and determines the flowability and uniformity of dyestuff in applications. The standard details the equipment requirements, test procedures and data processing methods for determination using swirl/spin Viscosity meters to ensure the accuracy and Repeatability of the test. The standard provides a scientific basis for liquid dyestuff quality control and has important guiding significance in the production and application of dyestuff.
