Plastics. Epoxy resins. Determination of electrical conductivity of aqueous resin extracts1 Scope This International Standard 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
