SPECIFICATION OF TECHNICAL GRADE SULPHUR
HEXAFLUORIDE (SF ) AND COMPLEMENTARY GASES
6
TO BE USED IN ITS MIXTURES FOR USE IN ELECTRICAL EQUIPMENT

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 60376 has been prepared by IEC technical committee 10: Fluids
for electrotechnical applications.
This third edition cancels and replaces the second edition published in 2005. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the requirements for the use of SF in electrical equipment have been confirmed;
6
b) a specification for complementary gases to be used in SF mixtures with N and CF has
6 2 4
been included;
c) the introduction and scope have been merged;
d) a new repartition of the annexes of IEC 60376, IEC 60480 and IEC 62271-4 has been
included.

SPECIFICATION OF TECHNICAL GRADE SULPHUR
HEXAFLUORIDE (SF ) AND COMPLEMENTARY GASES
6
TO BE USED IN ITS MIXTURES FOR USE IN ELECTRICAL EQUIPMENT



1 Scope
This document defines the quality for technical grade sulphur hexafluoride (SF ) and
6
complementary gases such as nitrogen (N ) and carbon tetra-fluoride (CF ), for use in
2 4
electrical equipment. Detection techniques, covering both laboratory and in-situ
portable instrumentation, applicable to the analysis of SF , N and CF gases prior to the
6 2 4
introduction of these gases into the electrical equipment are also described in this document.
This document provides some information on sulphur hexafluoride in Annex A and on the
environmental effects of SF in Annex B.
6
Information about SF by-products and the procedure for evaluating the potential effects of
6
SF by-products on human health are covered by IEC 60480, their handling and disposal
6
being carried out according to international and local regulations with regard to the impact on
the environment. Handling of SF and its mixtures is covered by IEC 62271-4.
6
Procedures to determine SF leakages are described in IEC 60068-2-17.
6
For the purposes of this document, the complementary gases used in SF mixtures will be
6
limited to N or CF .
