Plastics — Epoxy resins — Part 2: Preparation of test specimens and determination of properties
ISO 3673-2:2007 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of epoxy resins. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given. Properties of crosslinked epoxy resins have been selected from the general test methods in ISO 10350‑1:1998. Other test methods in wide use with, or of particular significance to, epoxy resins, particularly properties useful for the processing of non-crosslinked epoxy resins, are also included.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3673-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 12, Thermosetting
materials.
This second edition cancels and replaces the first edition (ISO 3673-2:1999), which has been technically
revised.
ISO 3673 consists of the following parts, under the general title Plastics — Epoxy resins:
⎯ Part 1: Designation
⎯ Part 2: Preparation of test specimens and determination of properties

Introduction
The purpose of this part of ISO 3673 is to designate procedures for the determination of intrinsic properties of
epoxy resins (EP). It specifies procedures and conditions for the preparation of test specimens of epoxy resins
in a specified state, and methods for measuring their properties. Those properties and test methods which are
suitable and necessary for characterizing epoxy resins are listed. Because of the specificity of thermosetting
resins like epoxy resins, contrary to other plastic products, a distinction is made between the presentation of
the properties before crosslinking (characteristics which are useful for processing) and after crosslinking
(intrinsic characteristics).

SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory
practice, if applicable. This document does not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any regulatory requirements.
1 Scope
This part of ISO 3673 specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of epoxy resins. Requirements for handling test material and for conditioning
both the test material before moulding and the specimens before testing are given.
Properties of crosslinked epoxy resins have been selected from the general test methods in
ISO 10350-1:1998. Other test methods in wide use with, or of particular significance to, epoxy resins,
particularly properties useful for the processing of non-crosslinked epoxy resins, are also included in this part
of ISO 3673.
In order to obtain reproducible and comparable test results, it is necessary to use the test methods, sample
preparation and conditioning, and specimen dimensions specified herein. Values determined will not
necessarily be identical to those obtained using test specimens of different dimensions or prepared using
different procedures.
Other standards exist concerning the determination of properties and preparation of test specimens for epoxy-
based products, to which reference will be made, if required.
