IEC 61099:2010

Insulating liquids - Specifications for unused synthetic organic esters for electrical purposes

IEC 61099:2010 covers the specification and test methods for unused synthetic organic esters. It applies to synthetic organic esters, delivered to the agreed point and time of delivery intended, for use in transformers, switchgear and similar related equipment in which synthetic organic esters are required as an insulant and for heat transfer. The main changes of this new edition with respect to the previous one relate to the aim of giving a more updated specification of synthetic organic esters when used as insulating liquids.

Liquides isolants - Spécifications relatives aux esters organiques de synthèse neufs destinés aux matériels électriques

La CEI 61099:2010 couvre les spécifications et les méthodes d'essai relatives aux esters organiques de synthèse neufs. Elle est applicable aux esters organiques de synthèse, livrés au lieu et à la date de livraison convenus, destinés à être utilisés dans les transformateurs, les appareillages de connexion et matériels connexes analogues dans lesquels les esters organiques de synthèse sont exigés comme isolant et pour le transfert de chaleur. Les modifications principales de cette nouvelle édition par rapport à l'édition précédente ont pour objectif de fournir une spécification plus à jour concernant les esters organiques de synthèse lorsqu'ils sont utilisés en tant que liquides isolants.

INSULATING LIQUIDS –
SPECIFICATIONS FOR UNUSED SYNTHETIC
ORGANIC ESTERS FOR ELECTRICAL 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 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 61099 has been prepared IEC technical committee 10: Fluids for
electrotechnical applications.
This second edition cancels and replaces the first edition published in 1992 and constitutes a
technical revision.
The main changes with respect to the previous edition relate to the aim of giving a more
updated specification of synthetic organic esters when used as insulating liquids.
