标准摘要
[中文适用范围]： 本国际标准规定了一种方法，用于测定在 95 °C 下用水萃取环氧树脂所得的水萃取物的电导率。该方法仅适用于在萃取温度（95 °C）下呈熔融状态的环氧树脂。该方法对于用作电子设备绝缘材料的环氧树脂非常重要。萃取物的电导率用作树脂中离子物种浓度的量度。 [外文原描述]： ISO 21318:2007 specifies a method for the determination of the electrical conductivity of an aqueous extract obtained by extraction of an epoxy resin with water at 95 °C. The method is applicable only to epoxy resins that are in the molten state at the extraction temperature (95 °C). The method is important for epoxy resins which are used as insulation materials for electronic devices. The electrical conductivity of the extract is used as a measure of the concentration of the ionic species in the resin.
