INTERNATIONAL ELECTROTECHNICAL COMMISSION
REFERENCE TAPES FOR VIDEO RECORDER SYSTEMS
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.
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.
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)121 60B(CO)131
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.

REFERENCE TAPES FOR VIDEO TAPE RECORDER SYSTEMS
1 Scope
This International Standard describes the general requirements for reference tapes
applicable to various video tape recorder (VTR) formats.
The object of this standard is to enable users of magnetic recording systems to compare
technical product data from different manufacturers and to enable compatibility within the
VTR format.
Currently available VTRs, adjusted with the IEC reference tape appropriate to the corres-
ponding IEC VTR standard, should give satisfactory results with currently available tapes.
The information within this standard covers existing IEC formats. For future formats the
corresponding information will be included in the IEC standard which defines the individual
system.
