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.
Abstract
Overview
ISO 21318:2007 specifies a standardized test method for determining the electrical conductivity of aqueous extracts of epoxy resins. The method measures ionic species in an extract produced by water extraction at 95 °C and is intended for epoxy resins that are molten at that temperature. The measured conductivity serves as an aggregate indicator of ionic impurities (e.g., chloride, sodium, catalyst residues) that can impair epoxy insulation in electronic devices.
Key topics and technical requirements
- Scope: Applicable only to epoxy resins molten at 95 °C; used primarily for electronic insulation materials.
- Extraction conditions: Test portion 8.00 g ± 0.05 g with 80 ml ± 2 ml distilled/deionized water (conductivity
