Classification of insulating liquids according to fire point and net calorific value

Defines a system for classifying insulating liquids according to fire-point and net calorific value. The characteristics on which the system is based are given together with limiting values.

Einteilung von Isolierflüssigkeiten nach dem Brennpunkt und dem spezifischen Heizwert

CLASSIFICATION OF INSULATING LIQUIDS
ACCORDING TO FIRE-POINT
AND NET CALORIFIC VALUE
FOREWORD

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.

2) They have the form of recommendations for international use and they are accepted by the National

Committees in that sense.

3) In order to promote international unification, the IEC expresses the wish that all National Committees

should adopt the 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.

This International Standard has been prepared by IEC Technical Committee No. 10: Fluids

for electrotechnical applications.
The text of this standard is based on the following documents:

INTRODUCTION

IEC Publication 76-2: 1976, Power transformers — Part 2: Temperature rise, includes a

classification system for identifying transformers based on type of cooling medium and the

method of coolant circulation. Insulating liquids were classified therein according to their

fire behaviour into classes O (mineral oil or equivalent combustible synthetic insulating

liquids), and L (non-flammable synthetic insulating liquids). In 1984, IEC/TC 10 undertook

a classification of insulating liquids according to fire behaviour. Pending IEC/TC 10

proposals, CENELEC/TC 14 drafted such a classification based on fire-point adding to the

former classes O and L a new class K for liquids with fire-point above 300 °C.
