116 FOREWORD
117 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
118 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
119 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
120 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
121 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
122 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
123 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
124 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
125 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
126 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
127 consensus of opinion on the relevant subjects since each technical committee has representation from all
128 interested IEC National Committees.
129 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
130 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
131 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
132 misinterpretation by any end user.
133 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
134 transparently to the maximum extent possible in their national and regional publications. Any divergence between
135 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
136 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
137 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
138 services carried out by independent certification bodies.
139 6) All users should ensure that they have the latest edition of this publication.
140 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
141 members of its technical committees and IEC National Committees for any personal injury, property damage or
142 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
143 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
144 Publications.
145 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
146 indispensable for the correct application of this publication.
147 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
148 rights. IEC shall not be held responsible for identifying any or all such patent rights.
149 International Standard IEC 60455-2 has been prepared by IEC technical committee 15: Solid
150 electrical insulating materials.
151 This third edition cancels and replaces the second edition published in 1998. This edition
152 constitutes a technical revision.
153 This edition includes the following significant technical changes with respect to the previous
154 edition:
155 a) Introduction of test methods related to IEC 60455-3-8;
156 b) Additional and updated test methods for resins

177 INTRODUCTION
178 This part of IEC 60455 is one of a series which deals with solvent-free resin based reactive
179 compounds and their components used for electrical insulation.
180 The series consists of three parts:
181 – Part 1: Definitions and general requirements (IEC 60455-1);
182 – Part 2: Methods of test (IEC 60455-2);
183 – Part 3: Specifications for individual materials (IEC 60455-3).
184 The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed
185 that compliance with this document may involve the use of a patent. IEC takes no position
186 concerning the evidence, validity, and scope of this patent right.
187 The holder of this patent right has assured IEC that s/he is willing to negotiate licences under
188 reasonable and non-discriminatory terms and conditions with applicants throughout the world.
189 In this respect, the statement of the holder of this patent right is registered with IEC. Information
190 may be obtained from the patent database available at patents.iec.ch/.
191 Attention is drawn to the possibility that some of the elements of this document may be the
192 subject of patent rights other than those in the patent database. IEC shall not be held
193 responsible for identifying any or all such patent rights.
