This table presents nominal data. Actual values, provided with each standard, may vary slightly from lot to lot and formulations are subject to change. If your application requires close conformity with published nominal values, please contact technical service to obtain the actual viscosity values associated with the current formulation.
Thomas®-Stormer® Viscosity Standards
Thomas-Stormer viscosity standards calibrate manual and electronic Thomas-Stormer viscometers. The KREBS UNIT (KU) is often used for Thomas-Stormer viscometers. Lot specific viscosity data (in cP and KU) is provided with each standard at 23 °C, 24 °C, 24.5 °C, 25 °C, 25.5 °C and 26 °C.
