FOREWORD
The formal decisions or agreements of the I E C 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

sense.
tional Committees should adopt the
3) In order to promote international unification, the I E C expresses the wish that all Na
text of the I E C recommendation for their national rules in so far as national conditions will permit. Any divergence
between the I E C 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 13B, Electrical Measuring Equipment, of
I E C Technical Committee No. 13, Electrical Measurements.
Drafts were discussed at the meetings held in The Hague in 1975 and in Warsaw in 1976. As a
result of this latter meeting, t
