Procedure
- Place flow cup in a precisely horizontal position using ring stand or temperature control jacket
- Close orifice
- Pour in test liquid
- Draw a clean glass plate over the rim of the cup, removing superfluous liquid into the overflow reservoir and closing the cup
- Remove glass plate horizontally
- Open the orifice and start the stopwatch simultaneously
- Stop the watch with the first break in the efflux stream
- Repeat the measurement three times, each with a new sample of the same material
Knowledge
Guide to Viscosity Measurement
Viscosity is an important property of liquids to determine how they flow, spread, or level under certain conditions. It can be defined as a liquid’s internal resistance to flow. Being able to measure the viscosity will allow to predict the behavior in a process or an application. When applying a paint by roll application the paint viscosity will strongly influence the amount of paint applied per surface area, thereby determining both yield and hiding power. It is crucial for liquid products to undergo a viscosity measurement in incoming and outgoing QC.
