For ink and paint viscometers For use with Zahn, Shell and Ford viscometer cups. Based on NIST value of 1.0016 centipoise for water at 20°C. Traceable to NIST. Approximate kinematic viscosity and drain times for the various cups at 25°C are given in table. Actual values are furnished with each standard.
