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 3.
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 part of ISO 3673 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 3673-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 12, Thermosetting materials.
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

ISO 3673-2:1999(E)
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 the 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).

Part 2:
Preparation of test specimens and determination of properties
WARNING — Persons using this part of ISO 3673 should be familiar with normal laboratory practice. This
part of ISO 3673 does not purport to address all of the safety problems, 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 national regulatory conditions.
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 here.
Properties of crosslinked epoxy resins have been selected from the general test methods in ISO 10350:1993. Other
test methods in wide use, 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.
2 Normative references
