INTERNATIONAL ELECTROTECHNICAL COMMISSION
ANALOGUE AUDIO RECORDING

POLARITY OF MAGNETIZATION
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) 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.
They have the form of recommendations for international use published in the form of standards, technical
3)
reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
International Standard IEC 1213 has been prepared by sub-committee 60B: Video
recording, of IEC technical committee 60: Recording.
The text of this standard is based on the following documents:

ANALOGUE AUDIO RECORDING
ON VIDEO TAPE -
POLARITY OF MAGNETIZATION
1 Scope
This International Standard applies to audio recording and processing, and gives
requirements for the preservation of signal polarity, together with methods of test which
are not already included in other standards.
It is based on, and consistent with, the relevant text in IEC 268-2, and the connector
applications standardized in IEC 268-11 and IEC 268-12.
NOTE - Polarity characteristics of audio transducers are dealt with in IEC 268-4, IEC 268-5 and IEC 268-9.
