Procedure

Each cup has a 12-inch loop handle to allow the cup to be dipped by hand into a liquid container. At the center of this handle is a finger-ring for holding the cup in a vertical position during use. Results should be reported in Zahn-Seconds at a specified temperature for a particular cup.

  • Conversion of Zahn-Seconds to Centistokes (ASTM D 4212):
    Centistokes = K * efflux time - (C / efflux time)
  • Conversion of Centistokes to Centipoise:
    Centistokes x Specific Gravity

  Conversion Factors:     K = 23,56            C = 744
