标准范围

对于将此类树脂用作浸渍材料的应用非常重要。该原理基于向树脂溶液中添加丙酮/水混合物。允许由此产生的沉淀物沉淀，并测量树脂上方剩余悬浮液的电导。然后根据测得的电导率计算电导率，单位为每厘米微西门斯。

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.
