Foreword
The text of document 10/619/FDIS, future edition 2 of IEC 60836, prepared by IEC TC 10, Fluids for
electrotechnical applications, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60836 on 2005-06-01.
This European Standard supersedes HD 565 S1:1993.
It includes the following major technical changes:
a) the title has been modified;
b) the scope has been adapted to meet the changes in the title;
c) health, safety and environmental requirements have been revised in order to follow the
environmental practice carried out for other insulating liquids. Isopropyl alcohol now replaces
chlorinated dissolvents for cleaning test equipment;
d) Clause 8 replaces Section 2 of HD 565 S1. In line with other TC 10 documents, EN ISO 2592
(ISO 2592, not modified) is now the only method specified for measuring fire point and EN 60814
(IEC 60814, not modified) for water content. Breakdown voltage measurement has now been
transferred to EN 60156 (IEC 60156, not modified);
e) Table 1 replaces Sheet 1 of HD 565 S1. Two technical changes have been made:
– the minimum fire point is increased from 330 °C to 340 °C (in conformity with ASTM D4652)
and recognizes also that the test values registered for production are even higher.
– neutralization values have been reduced from 0,02 mg KOH/g to 0,01 mg KOH/g, in line with
production test data.
f) Annex A has been deleted.
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) 2006-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-06-01
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 60836:2005 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 61039 NOTE Harmonized as HD 618 S1:1992 (not modified).
IEC 61100 NOTE Harmonized as EN 61100:1992 (not modified).

SPECIFICATIONS FOR UNUSED SILICONE INSULATING LIQUIDS
FOR ELECTROTECHNICAL PURPOSES
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
