Procedure
- Select the proper number cup to be used from the Specification Table, which is dependent on the expected viscosity range of the material to be measured.
- Insure that the cup is clean and that there is no residual dried material in or around the orifice.
- Adjust the temperature, if necessary, of the test material.
- Completely immerse the cup into the material to be measured in a location free from bubbles or foam, holding the cup vertically by means of the stainless steel split key ring.
- Measure and record the temperature of the material that is encompassed by the cup.
- Hold cup vertically by inserting index finger into handle ring. In a quick, steady motion, lift the cup out of the sample material, starting the timer when the top edge of the cup breaks the surface. During the flow time, hold the cup no more than 6” above the level of the sample material.
- Stop the timer when the first definite break in the stream at the base of the cup is observed.
- Record the number of seconds of efflux time, temperature and the cup number. (Example: No. 2 EZ™ Dip Cup, 48.1 seconds at 25.1°C.) As an option to the preceding step, refer to the Viscosity Calculator App or conversion table for the cup to determine the centistoke viscosity for the measured efflux time in seconds and record this value and the measured temperature.
- Promptly clean the cup unless it will be used immediately for a rerun of the same material. (Use a length of nylon fishing line to clean the orifice.)
