General Information
Gardner Dip Viscosity Cups (Zahn Type) are robust
instruments which are inexpensive and easy to
operate. They may be used anywhere to test the
viscosity of a wide variety of fl uids in accordance
with ASTM Standard Test Methods 0816, DI084,
or D4212. Ranges of viscosity from about 20 to
1800 centistokes (cSt) for different materials can
be evaluated with a set of fi ve different cups as
shown in Table 1.
Table 1
Cup No. Viscosity Range (cSt) Application (material)
1 60 max very thin liquids
2
20 – 230 thin oils, mixed
paints, lacquers
3 150 – 850 medium oils, mixed
paints, enamels
4 220 – 1100 viscous liquids and
materials
5 460 – 1840 extremely viscous
liquids and
materials
For very thin liquids with low viscosities up to a
maximum of 60 cSt, Cup No.1 should be used.
Cup No.2 can be used for thin oils, mixed paints,
and lacquers (viscosity range: 20 to 230 cSt). Me-
dium oils, mixed paints, and enamels in the 150 to
850 cSt range are best measured with Cup No.3.
