Viscosity Laboratory has developed high accuracy capability to support national viscosity measurement activities. The laboratory is also responsible to provide traceability in viscosity measurement in the country to the primary standard of viscosity. The chart illustrates the traceability scheme for viscosity measurement.
The highest standard maintained in the laboratory is Ubbelohde type Master Viscometer which is being utilized as a primary method for the transparent liquid viscosity measurement. A set of viscosity standards oil ranging from (0.9 to 85,000) mm²/s for kinematic viscosity and (0.7 to 75,000) mPa.s for dynamic viscosity enable NMIM to provide traceability for viscosity measurement at the temperature range of (20 to 100) °C.
