A number in parentheses indicates the year of.
Viscosity flow cup method.
And they are available in a range of designs in accordance with national and international standards with various orifice diameters to suit different viscosities.
If the standards stipulate conversion methods the flow time.
Viscosity cups remain the most important quick and simple method to measure the consistency of fluids in the laboratory and in production.
The number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.
Viscosity flow cups viscosity flow cups are very easy to use instruments made of anodized aluminium with a stainless steel orifice for measuring the consistency of paints varnishes and similar products.
Viscosity cups are however only suitable for lower viscosities and not for highly viscous substances such as pastes etc.
After making a measurement the flow cup particularly the nozzle must be carefully.
This precision din cup din viscosity flow cup is designed to measure the viscosity of sample liquids e g varnishes paints and related liquids and fluids.
The ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom.
To evaluate the viscosity of an experimental sample with this din flow cup the flow time measured in seconds s is converted into centistokes cst presenting the viscosity value.
The measured kinematic viscosity is generally expressed in seconds s flow time.
A flow cup is a cup of a specified size and volume with an overflow channel at the top and a hole of a defined size in the bottom.
However the conditions in a simple flow.
If a flow cup is used the principle works as described above but instead of exact capillary dimensions the volume of the cup and its outlet capillary need to be accurately defined.
Under ideal conditions this rate of flow would be proportional to the kinematic viscosity expressed in stokes and centistokes that is dependent upon the specific gravity of the draining liquid.
As a rule the equations for getting viscosity from the flow time are empirically determined for each cup by way of calibration tests with viscosity reference.
