Part 2: Laboratory a. c. resistors
FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
1)
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.
In order to promote international unification, the I E C expresses the wish that all National Committees should adopt the text of
3)
the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between the 1E
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 Instruments, of IE
Technical Committee No. 13, Electrical Measuring Equipment.
It forms Part 2 of 1E Publication 477 which, after revision, will be issued as Publication 477-1.
Drafts were discussed at the meetings held in The Hague in 1975 and in Warsaw in 1976. As a result of
this latter meeting, a draft, Document 13B(Central Office)54, and a corrigendum to it, Document
13B(Central Office)54A, were submitted to the National Committees for approval under the Six Months'
Rule in November 1976 and in April 1977 respectively. Though the Six Months' Rule document together
with the corrigendum were approved by the National Committees, further modifications became neces-
sary. Therefore, these amendments, Document 13B(Central Office)63, were submitted to the National
Committees for approval under the Two Months' Procedure in July 1978.
The National Committees of the following countries voted explicitly in favour of publication:
Argentina Hungary
Italy
Australia
Japan
Austria
Poland
Belgium
Romania
Brazil
South Africa (Republic of)
Canada
China Sweden
Switzerland
Denmark
Turkey
