Determination of the viscosity of a fluid

Calibration procedures provide you with a certificate demonstrating the traceability of your standards with respect to the international system of units. The LNE National Metrology Laboratory safeguards the preservation, development and improvement of France's mass unit as well as its transfer to industry.

Proposed calibration services

Determination of the viscosity of a fluid

The level of uncertainties depend on the specific characteristics of the tested fluids.

The calibration uncertainty is specific to the actual viscosity range.

The uncertainties inherent in the viscometers used are as follows:

  • from 0.001 to 0.05 mm2.s-2: 0.5%
  • from 0.05 to 5 mm2.s-2: 0.9%
  • from 5 to 100 mm2.s-2: 1.2%

Accreditation details

This service is provided under COFRAC Accreditation No. 2-43
