FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
1)
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
2)
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 part of International Standard IEC 1119 has been prepared by Sub-Committee 60A:
Sound recording, of IEC Technical Committee No. 60: Recording.
The text of this part is based on the following documents:
DIS Report on Voting
60A(CO)129 60A(CO)134
Full information on the voting for the approval of this part can be found in the Voting
Report indicated in the above table.
