Introduction

The purpose of this document is to provide an overview of the test methods used to characterize epoxy resins, listing those suitable and necessary to characterize epoxy resins prior to polymerization. test methods, and a brief description of the principles involved. Appendix B provides a summary of test methods for epoxy resins. Due to the particularity of thermosetting resins (such as epoxy resins), the properties before crosslinking (useful properties for processing) and after crosslinking (intrinsic properties) There is a difference between performance. Test procedures for determining the intrinsic properties of crosslinked (or cured) epoxy resins are given in ISO 3673-2. Test methods for plastic epoxy resins

1 Scope

This document describes methods for the determination of the physical and chemical properties of epoxy resins. This document applies to the determination of the physical and chemical properties of epoxy resins.
