Specifications for unused silicone insulating liquids for electrotechnical purposes

This International Standard covers specifications and test methods for unused silicone liquids
intended for use in transformers and other electrotechnical equipment.
The specified characteristics of silicone transformer liquid classified as L-NTUK-8360300 (in
accordance with IEC 61039) are described in Table 1.
Besides the standard transformer applications there are other applications of silicone liquids,
such like cable accessories, capacitors, electrical magnets etc. The specified characteristics
and minimum requirements for these liquids are described in Table 2.
NOTE Maintenance of used silicone liquid in electrotechnical equipment is covered in a separate publication
IEC 60944.

Anforderungen an ungebrauchte Silikonisolierflüssigkeiten für elektrotechnische Anwendungen

Spécifications pour liquides isolants silicones neufs pour usages électrotechniques

IEC 60836:2015 couvre les spécifications et les méthodes d essai pour les liquides silicones neufs destinés à être utilisés dans les transformateurs et tout autre appareil électrotechnique. Outre les applications normalisées dans les transformateurs, il existe d autres applications pour les liquides silicones, telles que les accessoires de câble, les condensateurs, les électro-aimants, etc. Cette édition inclut les modifications techniques majeures suivantes par rapport à l édition précédente: a) la classification des liquides selon l'IEC 61039 a été adaptée par rapport à la dernière édition de l'IEC 61039:2008; b) la classification des liquides selon l'IEC 61100:1992 a été éliminée du fait de la suppression de ladite IEC 61100; c) les exigences minimales relatives aux autres liquides silicones pour usages électrotechniques ont été ajoutées.

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 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 pu
