Ford Viscosity Cups

It is helpful, and results will be more consistent, if all viscosity determinations are made in a room that is free from drafts or quick temperature change, and is within ±3°C (±5°F) of the viscosity measuring temperature of 25°C.

Ford Dip Cups

The Gardco Mini Dip Cups should have the same care as the Gardco Standard Series as they are produced to the same close tolerance.  The use of the dip cup, however, is somewhat different:

1. Adjust the temperature of the material to be measured, if necessary.  Lower the cup into the material so that the cup rim is submerged.  Place a thermometer into the cup as it is immersed and determine the temperature of the confined sample.  Remove thermometer.  Quickly raise the cup from the material, high enough to easily observe the efflux stream and at the same time, start the timer.  Closely observe the efflux stream and stop the timer at the first break in the stream, one to two inches below the orifice.
2. Record the cup used (ex., Gardco Mini Dip #4), the measured temperature and the efflux time.  If the efflux time is immediately converted to Gardco Standard Cup time by multiplying by two, it should be so noted.
3. Promptly clean the cup with close attention to the orifice.
