FIELD: test engineering.
SUBSTANCE: method includes measurement of viscosity ratio of solution with not less, than three capillary viscosity meters with different square areas of capillary tubes cross sections while maintaining laminar flow of solution and thermo stating. At that the method considers the rate of solution shear. Viscosity of alkali-aluminate solutions, corresponding to a shear rate of So=0, is evaluated with an accepted formula.
EFFECT: upgraded accuracy of measurement.
