FOREWORD
I) The formal decisions or agreements of the I EC 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
2)
sense.
In order to promote international unification, the I EC expresses the wish that all National Committees should adopt the text of
3)
the I EC recommendation for their national rules in so far as national conditions will permit. Any divergence between the I EC
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 12C: Transmitting Equipment, of I EC Technical
Committee No. 12: Radiocommunications.
The text of this standard is based on the following documents:

INTRODUCTION
This standard is one of a series of pa rts of I EC Publication 244.
This standard shall be used in conjunction with Publication 244-12-1. Its updated issue will be pub-
lished while the parts of IEC Publication 244 dealing with methods of measurement of characteristics
listed in these tables are being revised.
It is advisable to check if this is the latest issue.
