Zancup is a viscosity measuring device widely used in the paint industry. It is typically a stainless steel cup with a small hole in the middle of the bottom. It also has a long handle on the side. There are 5 cup specifications and marked as Zaan Cup #x. x is numbered from 1 to 5 (see table below) Larger number cups are used for high viscosity and smaller cups are used when viscosity is low. Manufactured in accordance with ASTM D 4212, ASTM D1084, and ASTM D816.
To measure the viscosity of the liquid, soak the material in the cup and fill it completely. After lifting the cup from the substance, measure the time before the liquid flows out of the cup breaks down, this is the corresponding "spill time". Standard paint specifications show viscosity: spill time, Zahn cup numbers.
Here, T is the spill time and v is the dynamic viscosity of the inch stokes.
Zarn cup #1:v = 1.1 (t - 29)
Zarn cup #2:v = 3.5 (t - 14)
Zern cup #3: v = 11.7(t - 7.5)
Zarn cup #4:v = 14.8(t - 5)
Zern Cup #5:v = 23t
