![]() Results should be reported in Zahn-Seconds at a specified temperature for a particular cup. Īscott Zahn Cups are based on measuring the Flow of liquid in seconds. Gardco signature Zahn cups and Gardco EZ Zahn cups use different conversions. With most substances, the amount of force and/or the amount of time the force is applied will alter a substance. Elija tapas de inmersión que cumplan con los estándares de prueba ASTM D1084 y D4212. TQC Sheen Viscosidad Immersion Zahn Cup ofrece una gama de copas de viscosidad de acero inoxidable (SS303) con una boquilla cavidad interior fija de acero inoxidable y mango. Viscosity is the measure of how hard it is to force a substance into motion, or flow. TQC Sheen Viscosity Cup ASTM D1084 D4212 Immersion Zahn. Note the above equations are for a Brookfield series of Zahn cups. The consistometer can only tell you how far your product will spread under its own weight in the amount of time you set. One can convert efflux time to kinematic viscosity by using an equation for each cup specification number, where t is the efflux time and ν is the kinematic viscosity in centistokes. ![]() As a reminder, ISO 2431 cuts also comply with NF T 30 070, DIN 53224. Zahn Cup Technical Specification Conversion How to convert flow time to viscosity in cSt Time-viscosity conversion of ISO 2431 cuts. On paint standard specifications, one denotes viscosity in this manner: efflux time, Zahn cup number. This Technical Information Paper provides information on the proper methods of measuring starch adhesive viscosity using the Stein Hall cup and the Harper Love cup. Starch viscosity is measured with either a Stein-Hall cup or a Love cup and is simply a measure of the time for a fixed amount of adhesive to pass through an opening in the bottom of the cup. After lifting the cup out of the substance the user measures the time until the liquid streaming out of it breaks up, this is the corresponding "efflux time". Viscosity of any liquid is defined as a measurement of the fluid’s resistance to flow. To determine the viscosity of a liquid, the cup is dipped and completely filled with the substance. They are manufactured in accordance to ASTM D 4212, ASTM D1084 and ASTM D816 Large number cup sizes are used when viscosity is high, while low number cup sizes are used when viscosity is low. There are five cup specifications, labelled Zahn cup #x, where x is the number from one through five (see table below). Viscosimeter type Stein Hall is worldwide used for the control of the viscosity of starch adhesives, widely used for the production of corrugated fibreboard.

There is also a long handle attached to the sides. viscosity that allows maximum coverage to seal the pits and fissures as well. It is commonly a stainless steel cup with a tiny hole drilled in the centre of the bottom of the cup. A Zahn cup is a viscosity measurement device widely used in the paint industry.
