Materials and methods

Test guideline
Qualifier:
according to
Guideline:
NF T60-100 (Petroleum products. Transparent and opaque liquids. Determination of kinematic viscosity and calculation of dynamic viscosity; identical to ISO 3104)
Deviations:
no
Principles of method if other than guideline:
The cinematic viscosity was determined at 20°C with the Ubbelohde viscometer; It is an u-shaped pieces of glassware with a reservoir on one side and a measuring bulb with a capillary on the other.A liquid is introduced into the reservoir then sucked through the capillary and measuring bulb. The liquid is allowed to travel back through the measuring bulb and the time it takes for the liquid to pass through two calibrated marks is a measure for viscosity. The Ubbelohde device has a third arm extending from the end of the capillary and open to the atmosphere. In this way the pressure head only depends on a fixed height and no longer on the total volume of liquid.
GLP compliance:
no
Type of method:
capillary viscometer (static)
