Resumen

Important for applications in which such resins are used as impregnating materials. The principle is based on addition of an acetone/water mixture to a solution of the resin. The precipitate thus produced is allowed to settle, and the conductance of the suspension remaining above the resin is measured. The conductivity, expressed in microsiemens per centimetre, is then calculated from the measured conductance.
