REQUIREMENTS FOR GREASES FOR ALUMINIUM,
ALUMINIUM ALLOY AND STEEL BARE CONDUCTORS
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 61394 has been prepared by IEC technical committee 7: Overhead
electrical conductors.
This first edition of IEC 61394 cancels and replaces the first edition of technical specification
IEC/TS 61394 published in 1997. It constitutes a technical revision and now has the status of
an International Standard.
The text of this standard is based on the following documents:
FDIS Report on voting
7/609/FDIS 7/613/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.
A bilingual version of this publication may be issued at a later date.

REQUIREMENTS FOR GREASES FOR ALUMINIUM,
ALUMINIUM ALLOY AND STEEL BARE CONDUCTORS
1 Scope
This International Standard specifies the requirements and tests of greases designed for
corrosion protection of bare overhead conductors.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 60068-2-11:1981, Basic environmental testing procedures – Part 2-11: Tests – Test Ka:
Salt mist
lSO 2137:2007, Petroleum products and lubricants – Determination of cone penetration of
lubricating greases and petrolatum
ISO 2176:1995, Petroleum products – Lubricating grease – Determination of dropping point
3 Designation system
Greases shall be designated θ Aθ or θ Bθ where A and B define the type of grease as
1 2 1 2
follows:
– type A: products generally applied in the cold state, for example greases: semi-solid or
solid products consisting essentially of a stabilized mixture of mineral or synthetic oil and
thickeners such as metal soaps or inorganic compounds;
– type B: products generally applied in the hot state, for example petrolatum: semi-solid, or
solid products made up essentially of microcrystalline waxes associated with small
quantities of mineral oil and organic additives;
– θ is the lowest temperature in °C below 0 °C at which the grease will perform the
1
requirement of protection of the conductor from atmospheric corrosion;
– θ is the highest temperature, in °C, at which the grease will perform to this requirement
2
(achieve specified drop point or high temperature stability).
Examples:
− 20A150 type A grease with a temperature θ of -20 °C and θ of 150 °C.
1 2
− 20B110 type B grease with a temperature θ of -20 °C and θ of 110 °C.
1 2
The grease supplier shall provide a unique identifier for its grease, and shall retain details of
its composition for future reference. The composition shall include manufacturing tolerance
and shall remain unchanged while the grease is marketed under this specific identifier.
