Conversion Table - Gardco EZ ZAHN Dip Viscosity Cup Series Instruction Manual

for the stainless steel cups. Acetone is commonly used as the second solvent because of its high volatility and
its ability to dissolve traces of petroleum solvents and water.
In the third process a low velocity stream of clean air will be suffi cient to evaporate remaining traces of any
volatile solvent. Be aware, avoid rapid evaporation of these solvents as this can cool the surface to such an
extent that humid air may be brought below the dew point, causing a fi lm of water to form on the cup.

BETWEEN EFFLUX TIME IN SECONDS AND CENTISTOKES
Flow characteristics of the EZ™ Dip Viscosity Cups are very accurately defi ned by mathematical formula
relating them to the viscosity of standard oils which are traceable to the National Institute of Standards and Tech-
nology. The formula for each cup in the series is shown on the cup graphs of prior pages. For convenience, the
formula for each cup has been solved for each tenth second within the normal cup range. Results are available
in table form as shown above and are furnished with each cup. They are also available in sets of fi ve for the fi ve
cup series.
Use the table as follows: Assume an effl ux time of 45.6 seconds. Read down the left column to the 45.0 line
and then to the right on this line to the 0.6 column. The value at the intersection is 111.3 centistokes. The tables
may be read in reverse to fi nd effl ux time in seconds from a known centistoke value.
