![]() The first moment the flow breaks (is not consistent) stop the watch. Pull up and as soon as the cup breaks the surface start the stop watch. Next put your stop watch in one hand and grab the viscosity cup with your other hand. Get a reading of the temperature from the liquid and record it. The larger the cup the longer it should sit. Let the cup sit for an additional 1-5 minutes depending on the mass. Next stir the liquid in order to ensure uniform temperature and density. Twist several times in order to dislodge any air bubbles from within the cup. Submerge the dip cup completely in the liquid being measured. Using abrasive cleaning materials such as a wire brush could damage the cup again causing issues in accuracy. ![]() Dirty equipment will impact the accuracy of the test. Using a suitable solvent clean the cup, handle and orifice to verify there is no residue. ![]() Validate there are no pre-set standards since certain viscosity tests have unique flow time standards. If not listed, select a cup that will give an estimated flow time of 30 - 100 seconds. ![]() Blast Hose, Nozzle Holders and Couplingsġx Stop Watch Determine The Proper Dip Cupįirst check the products technical data sheet to see if a dip cup has been listed.
