INTERNATIONAL ELECTROTECHNICAL COMMISSION
ACCEPTANCE INSPECTION OF CLASS 2 ALTERNATING-CURRENT
WATTHOUR METERS
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 conditions will permit. Any divergence between the IEC recommen-
dation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.
PREFACE
This report has been prepared by Sub-Committee 13A, Integrating Meters, of IEC Technical Committee
No. 13, Measuring Instruments.
Drafts were discussed at the meetings held in Budapest in 1970, in S tresa in 1971 and in Toronto in 1972.
As a result of this latter meeting, a draft, document 13A(Central Office)35, was submitted to the National
Committees for approval
