SIGNIFICANCE AND USE
4.1 These test methods can be used for research, quality control, or specification tests to characterize isocyanates used in polyurethane products.  
4.2 Viscosity measures the resistance of a fluid to uniform continuous flow without turbulence or other forces.  
4.3 Some isocyanates exhibit non-Newtonian behavior under certain conditions. Whenever possible, generate results for comparison under the same conditions, that is, the same spindle/speed combination for rotational viscosity and the same tube size for kinematic viscosity.
SCOPE
1.1 These test methods (A and B) determine the viscosity of crude or modified isocyanates. They are applicable to products derived from toluene diisocyanate, methylene di(phenylisocyanate), and polymeric (methylene phenylisocyanate) (see Note 1).
Note 1: Test method A includes a procedure for measuring dynamic viscosity using a rotational instrument. Test method B is a general procedure for kinematic viscosity of isocyanate.
