PSL viscosity oil standards are supplied with UKAS certificates of calibration providing the user with official assurance of the competence of the calibration work carried out. UKAS certificates of calibration provide several temperatures as shown on the table below together with uncertainties of measurement.

PSL viscosity oil standards, supplied in 500mL containers, are Newtonian in character and are suitable for use with many types of viscometers including, in particular, glass capillary and rotational viscometers as well as flow cups.
