INTERNATIONAL ELECTROTECHNICAL COMMISSION
DETECTION AND DETERMINATION OF SPECIFIED ANTI-OXIDANT
ADDITIVES IN INSULATING OILS
FOREWORD
I) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use and they are accepted by the National Committees in that
2)
sense.
In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the
3)
text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence
between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the
latter.
PREFACE
This standard has been prepared by Sub-Committee 10A: Hydrocarbon Insulating Oils, of IEC
Technical Committee No. 10: Liquid and Gaseous Dielectrics.
Drafts were discussed at the meetings held in Baden-Baden in 1975 and in Moscow in 1977. As a
result of this latter meeting, a draft, Document 10A(Central Office)39, was submitted to the National
Committees for approval under the Six Months' Rule in August 1978.
The National Committees of the following countries voted explicitly in favour of publication:
Netherlands
Australia
Poland
Austria
Belgium Romania
South Africa (Republic of)
Bulgaria
Spain
Czechosl
