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.
rnational unification, the IEC expresses the wish that all National Committees should adopt
3) In order to promote inte
the text of the I EC 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.
PREFACE
This standard has been prepared by IEC Technical Committee No. 65: Industrial-process Measure-
ment and Control.
It forms Part 2 of IEC Publication 654.
The first draft was discussed at the meeting held in Munich in 1973. Further drafts were discussed at
the meetings held in Moscow in 1975 and in Budapest in 1976. As a result of this latter meeting, a draft,
Document 65(Central Office)13, was submitted to the National Committees for approval under the Six
Months' Rule in May 1977. Amendments, Document 65(Central Office)18, were submitted to the National
Committees for approval under the Two Months' Procedure in June 1978.
The following countries voted explicitly in favour of publication:
Austria Japan
Netherlands
Belgium
Romania
Bulgaria
South Africa (Republic of)
Canada
Spain
Czechoslovakia
Sweden
Denmark
Switzerland
France
Turkey
Hungary
Italy United Kingdom
The National Committees of Germany and Poland voted against the amendments circulated under the
Two Months' Procedure.
