High Temperature (HTHS) Viscosity Standards
 
CANNON high temperature viscosity standards are produced in accordance with ASTM D5481, Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer and ASTM D4741, Viscosity at High Temperature and High Shear Rate by Tapered Plug Viscometer. ASTM D6616 TBS tet at 100 °C applies to certain standards as well. Lot specific viscosity data in mPa·s (cP) is provided with each standard.
