Insulating liquids - Specifications for unused synthetic organic esters for electrical purposes (IEC 61099:2010)

This International Standard 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. These unused synthetic organic esters are obtained by chemical processing and physical treatments of fatty acids and polyols.

Liquides isolants - Spécifications relatives aux esters organiques de synthèse neufs destinés aux matériels électriques (CEI 61099:2010)

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.

Izolacijske tekočine - Specifikacije za neuporabljene sintetične organske estre za elektrotehniko (IEC 61099:2010)

Ta mednarodni standard zajema specifikacijo in preskusne metode za neuporabljene sintetične organske estre. Velja za sintetične organske estre, dostavljene na dogovorjeno mesto v predvidenem času, za uporabo v transformatorjih, stikalnih napravah in podobni povezani opremi, v kateri so sintetični organski estri potrebni kot izolator in za prenos toplote. Ti neuporabljeni sintetični organski estri se pridobivajo s kemično predelavo in mehansko obdelavo maščobnih kislin in poliolov.

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.
