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 15252 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15252-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 12, Thermosetting materials.
ISO 15252 consists of the following parts, under the general title Plastics — Epoxy powder moulding compounds
(EP-PMCs):
� Part 1: Designation system and basis for specifications
� Part 2: Preparation of test specimens and determination of properties
� Part 3: Requirements for selected moulding compounds

INTERNATIONAL STANDARD ISO 15252-2:1999(E)
Plastics — Epoxy powder moulding compounds (EP-PMCs) —
Part 2:
Preparation of test specimens and determination of properties
1 Scope
This part of ISO 15252 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of epoxy powder moulding compounds (EP-PMCs). Requirements for handling test
material and for conditioning both the test material before moulding and the specimens before testing are given
here.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the
materials from which these specimens are made are given. Properties and test methods which are suitable and
necessary to characterize PMCs are listed.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use
for, or of particular significance to, PMCs are also included in this part of ISO 15252, as are the designatory
properties found in ISO 15252-1.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and
conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not
necessarily be identical to those obtained using specimens of different dimensions or prepared using different
procedures.
