INDICATOR LIGHT UNITS FOR HOUSEHOLD AND SIMILAR
FIXED-ELECTRICAL INSTALLATIONS –
Part 1: General requirements
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 co-operation 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 express, as nearly as possible, an

international consensus of opinion on the relevant subjects since each technical committee has representation

from all interested National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical specifications, technical 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.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62094 has been prepared by subcommittee 23B: Plugs, socket-

outlets and switches, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23B/679/FDIS 23B/685/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

The committee has decided that the contents of this publication will remain unchanged until

2005-12. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INDICATOR LIGHT UNITS FOR HOUSEHOLD AND SIMILAR
FIXED-ELECTRICAL INSTALLATIONS –
Part 1: General requirements
1 Scope

This International Standard applies to stand-alone indicator light units intended to give a

visible signal. They are designed for a.c. only with a rated voltage not exceeding 440 V and

a rated power not exceeding 10 W, for household and similar fixed-electrical installations,

either indoors or outdoors.

NOTE 1 Indicator light units are not intended for lighting as a luminaire (see IEC 60598).

This standard does not apply to pilot lights incorporated in products complying with their own

standards which are tested as part of that product.

The standard also applies to boxes for indicator light units, with the exception of flush-

mounting boxes (according to IEC 60670) for flush-type indicator light units.

Indicator light units complying with this standard are suitable for use at ambient temperatures

not normally exceeding 25 °C, but occasionally reaching 35 °C.

In locations where special conditions prevail, as in ships, vehicles and the like and in

hazardous locations, for example where explosions are liable to occur, special constructions

may be required.

NOTE 2 LEDs and lamps are not considered as indicator light units, but as components.
