Properties of Liquids

The core topic of Working Group 3.32 "Properties of Liquids" is the precise determination of the thermophysical quantities of liquids. The focus is on the precise determination of 
viscosity and density (of [alternative] fuels and energy carriers, among others) and their traceability. In addition, the working group is engaged in the development of mass spectrometric methods for the chemical analysis of reactive processes as well as the accurate determination of the energy content of (bio-) fuels by bomb calorimetry.

Furthermore, the working group is involved in the preparation of standards in the field of density, viscosity and volume determination as well as for fuel properties and is also active in various committees. In addition, we are active in the context of expert assessments of calibration and testing laboratories for the measurands density, viscosity and volume on behalf of the German Accreditation Body (DAkkS).

We offer:

Newtonian calibration liquids for viscosity

Calibration of Ubbelohde viscometers

Calibration glasses for high-temperature measurements of the viscosity

Measurements of density and viscosity for customer samples

Calibration liquids for density

Conformity assessment according to module B for oscillation-type densimeters
