INTERNATIONAL ELECTROTECHNICAL COMMISSION
SPECIFICATION FOR UNUSED POLYBUTENES
FOREWORD
1) 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 condi-
tions will permit. Any divergence between the IEC recommendation and
the corresponding national rules should, as far as possible, be clearly
indicated in the latter.
4) The IEC has not laid down any procedure concerning marking as an
indication of approval and has no responsibility when an item of
equipment is declared to comply with one of its recommendations.
PREFACE
This standard has been prepared by Sub-Committee 10A: Hydrocarbon
insulating oils, of IEC Technical Committee No. 10: Fluids for electro-
technical applications. (This Sub-Committee has been superseded by
Committee 10.)
The text of this standard is based on the following documents:
Six Months' Rule Report on Voting
10A(C0)71 10(C0)246

SPECIFICATION FOR UNUSED POLYBUTENES
SECTION ONE GENERAL
1. Scope
1.1 This standard covers specifications and test methods for unused
polybutenes, as delivered, intended for use as insulating liquids in
electrical equipment.
The requirements given in Sheet 1 are only applicable to unused
polybutenes used as an impregnant for paper insulated capacitors and
cables and as a filling medium for pipe type cables.
Note.- Polybutenes may be used in transformers, but nowadays this
application is not wide enough to justify the development of
international specifications.
Action could be taken when needed.
1.2 For the purpose of this standard two grades of polybutenes are
considered: Class I and Class II based on the values of certain
physical properties namely: viscosity, flash-point and pour-point.
2. Definitions
2.1 Additive
A suitable substance, which is deliberately added to an insulating
liquid in small proportion in order to improve certain characteristics.
2.2 Polybutenes
Polyisobutylenes, which are normally referred to as polybutenes, are
branched chain polyolefi
