parallel vote and was approved by CENELEC as EN 60587 on 2007-06-01.
This European Standard supersedes HD 380 S2:1987.
The main changes from HD 380 S2:1987 are as follows:
– experience has indicated the need for improved description of the experimental method;
– for the preparation of the test specimens, abrasion is recommended only if necessary;
– the ventilation of the test chamber is described in detail;
– for specimens of soft elastomeric materials a mounting support is described;
– the maximum depth of erosion has to be reported in the classification.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-03-01
– latest date by which the national standards conflicting
(dow) 2010-06-01
with the EN have to be withdrawn

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60587 has been prepared by IEC technical committee 112:
Evaluation and qualification of electrical insulating materials and systems.
This third edition cancels and replaces the second edition, published in 1984, and constitutes
a technical revision. The main changes from the previous edition are as follows: experience
has indicated the need for improved description of the experimental method. For the
preparation of the test specimens abrasion is recommended only if necessary. The ventilation
of the test chamber is described in detail. For specimens of soft elastomeric materials a
mounting support is described. The maximum depth of erosion has to be reported in the
classification.

ELECTRICAL INSULATING MATERIALS
USED UNDER SEVERE AMBIENT CONDITIONS −
TEST METHODS FOR EVALUATING RESISTANCE TO TRACKING
AND EROSION
1 Scope
This International standard describes two test methods for the evaluation of electrical
insulating materials for use under severe ambient conditions at power frequencies (45 Hz to
65 Hz) by measurement of the resistance to tracking and erosion, using a liquid contaminant
and inclined plane specimens. The two methods are as follows:
– Method 1: constant tracking voltage;
– Method 2: stepwise tracking voltage.
NOTE 1 Method 1 is the most widely used method as there is less need for continual inspection.
NOTE 2 The test conditions are designed to accelerate the production of the effects, but do not reproduce all the
conditions encountered in service.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
