![]() ![]() standard ISO 2431ĪFNOR Cup 2,5, 4, 6, 8 mm. The EZ Viscosity Cup Series is a logical and necessary outgrowth of the standardization studies on the Zahn Signature Viscosity Cup and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard. ![]() Cup and orifice production tolerance permits replacement of the orifice. Many other types of flow cups are being used, depending on the industry or region.ĭin Cup 4 mm., standard DIN 53211 (cancelled) The Gardco/DIN 4mm viscosity cups conform to the flow characteristics specified by Deutsche Normen DIN 53211. The Biuged DIN and Dip Viscosity Cups are produced with an easily removable orifice. ![]() The original Ford Cup was based on Imperial (UK) measurement of the aperture.

It is important when using a Ford Cup and when retesting liquids that the temperature of the cup and the liquid is maintained, as ambient temperature makes a significant difference to viscosity and thus flow rate. Viscosity Calculator Enter your variables below for an automatic calculation. However, the conditions in a simple flow cup are seldom ideal for making true measurements of viscosity. 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. If this is not possible, it is recommended to use the viscosity / temperature calculator. Bring the section and sample to the required temperature. According to the flow stop method: choose a cup with a flow time of 30-300 seconds. I have been unsuccessful in my attempts to locate a chart using the resources I have available to me. 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. According to the fixed volume method: choose a cup with a flow time of 20-200 seconds. I am looking for a paint viscosity chart that will give me relative comparisons between a 2 EZ Zahn cup, a 3 EZ Zahn cup, and a 4 Ford cup, with the ideal temperature of the paint being 77 degrees. ![]()
