Viscosity Standards

Unsure about your viscosity results? Run a reference standard to find out, if you're getting the right numbers. At PSL Rheotek, we offer the full range of viscosity standards for ongoing verification and calibration

ISO 17025

ASTM D2162, ASTM D445-IP71, ASTM D446, ISO 3104, ISO 3105, BS188, ISO/IEC 17025.

The PSL Calibration Laboratory is a UKAS Accredited Calibration Laboratory, accredited to ISO 17025. The PSL Calibration Laboratory maintains a master viscometer scale calibrated to ASTM D2162.

Calibrations performed include the measurement of Viscosity Reference Standards in the temperature range -40 to 135 deg. C.

PSL Viscosity Reference Standards are suitable for the verification and calibration of glass capillary viscometers, flow cups, rotational viscometers & Cone and Plate viscometers.

Certified values are provided for kinematic viscosity, dynamic viscosity and density, together with uncertanties of measurement.

The following types of viscosity standards are available from PSL:

● kinematic viscosity
● low temperature
● high viscosity
● dynamic viscosity
