SOUND SIGNALLING DEVICES
FOR HOUSEHOLD AND SIMILAR PURPOSES

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62080 has been prepared by Technical Committee 23: Electrical
accessories.
This consolidated version of IEC 62080 consists of the first edition (2001) [documents
23/287/FDIS and 23/293/RVD] and its amendment 1 (2008) [documents 23/450/FDIS and
23/457/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
62080 © IEC:2001+A1:2008 – 5 –
Annexes A, B and C form an integral part of this standard.
In this standard, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.
Words in bold are defined in clause 3.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date,
the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

SOUND SIGNALLING DEVICES
FOR HOUSEHOLD AND SIMILAR PURPOSES

1 Scope
This International Standard applies to sound signalling devices with integral enclosures or to
sound signalling devices intended to be fitted into or supplied with enclosures according to
IEC 60670 intended for household and similar purposes with rated voltages not exceeding 250
V a.c. or 250 V d.c. and with rated power inputs not exceeding 100 VA. In these sound
signalling devices an indicating light having a rated input power not exceeding 10 VA may
also be incorporated.
These products are designated as "devices" throughout the remainder of the text.
This standard applies to fixed, portable and plug-in devices for indoor or outdoor use.
In locations where special conditions prevail, special constructions may be required.
NOTE 1 This standard or parts of it may be used as a guide for sound signalling devices having a voltage less
than 50 V a.c. or 75 V d.c. Additional requirements for sound signalling devices having a voltage less than
50 V a.c. or 75 V d.c. are under consideration.
NOTE 2 This standard does not cover the radio transmitting or receiving functions.

4 General requirements
Devices and enclosures shall be so designed and constructed that, in normal use, they are
reliable and operate without danger to the user or the surroundings.
Compliance is checked by fulfilling all the requirements and tests specified.
5 General notes on tests
5.1 The tests according to this standard are type tests.
5.2 Unless otherwise specified, the tests shall be carried out on a single specimen as
delivered under normal conditions of use, which shall satisfy all the tests applicable to the
device.
If the device is intended for several supply voltages, for both a.c. and d.c., more than one
specimen may be required.
NOTE If it is necessary to dismantle a device for certain tests, an additional specimen is necessary.
The test on constituent parts may require the provision of additional specimens of these parts.
If it is necessary to submit such specimens, they shall be presented at the same time as the
device.
5.3 Unless otherwise specified, the tests shall be carried out in the order of the clauses.
Before starting the tests, the device shall be supplied at rated voltage to verify that it is in
operating condition.
62080 © IEC:2001+A1:2008 – 13 –
5.4 The tests shall be carried out with the device or any removable parts placed in the most
unfavourable position which can occur in normal use.
5.5 Unless otherwise specified, the tests are carried out at an ambient temperature between
15 °C and 35 °C. In case of doubt, the tests are made at an ambient temperature of 20 °C ± 5 °C.
5.6 Devices for a.c. only shall be tested with a.c. at the rated frequency, if marked, and
those for a.c. and d.c. shall be tested at the more unfavourable supply.
Devices for a.c. which are not marked with a frequency range of 50 Hz to 60 Hz shall be tested
with either 50 Hz or 60 Hz, whichever is the more unfavourable.
Devices carrying an indication of the range of rated frequencies other than 50 Hz to 60 Hz shall
be tested at the most unfavourable frequency of the rated frequency range.
5.7 Devices designed for more than one rated voltage shall be tested on the basis of the
most unfavourable voltage as declared by the manufacturer.
5.8 Devices provided with adjustment means shall be tested with the adjustment set to the
most unfavourable position if the adjustment can be modified by the user.
Appropriate sealing is considered not to allow any modification of the adjustment means by the
user.
5.9 Devices are tested installed according to the manufacturer’s instructions:
– flush type devices are tested mounted in their appropriate enclosures;
– surface mounted devices are tested mounted as intended for normal use;
– portable devices intended to be supplied by means of a flexible supply cable are tested
with the appropriate cable attached to the device;
– plug-in devices intended to be inserted into a socket-outlet are tested with the device
mounted in an appropriate socket-outlet.
5.10 For devices having characteristics of both type D and type R (see clause 6), the tests
shall be carried out for both.
