FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
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.
The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
2)
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.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
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.
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
5)
equipment declared to be in conformity with one of its standards.
International Standard IEC 838-2-1 has been prepared by sub-committee 34B: Lamp caps
and holders, of IEC technical committee 34: Lamps and related equipment.
It is the first section of the multi-section standard IEC 838-2.
The text of this standard is based on the following documents:

Full information on the voting for the approval of this standard can be found in the repo
on voting indicated in the above table.
IEC 838-2-1 constitutes the first section of the multi-section standard IEC 838-2 and is
written in a form to utilize the basic requirements of IEC 838-1 and to state modifications
and additions as they apply to lampholders S14.
In this standard the following print types are used:
- requirements proper: in romain type;
test specifications: in italic type;
- notes: in small roman type.
