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 recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
This International Standard has been prepared by Sub-Committee 60B: Video recording,
of IEC Technical Committee No. 60: Recording.
The text of this standard is based on the following documents:
DIS Report on Voting
60B(CO)125
60B(CO)137
Full information on the voting for the approval of this standard can be found in the Voting
Report indicated in the above table.
Annex A forms an integral pa rt of this International Standard.
Annex B is for information only.
