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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
Standard plugs and socket-outlets are now available with various additional features such as
Wi-Fi extenders, remote switching, energy saving, etc. For the purposes of this document, these
features are called additional functions.
This part of the IEC 60884 series provides particular requirements for plugs and socket-outlets
which incorporate electronic components for the purpose of providing additional functions.
The additional functions are categorised into 3 groups:
– additional functions that control the output of the accessory (these products are often called
“smart sockets”, “smart socket-outlets” or “smart plugs”);
– additional functions being powered by the accessory which do not control the output;
– additional functions that have protective means (e.g. overvoltage protection) other than
Residual Current Devices.
The requirements that are common to all three categories are given in the main part of this
document. Specific requirements are given in Annex AA to Annex CC.
This part does not address additional functions that have already been covered by other parts
of the IEC 60884 series, for example, socket-outlets incorporating USB power supply which are
covered by IEC 60884-3-1.
It is recognised that provision of a dimming function in fixed and portable socket-outlets poses
a considerable safety risk to the loads that can be connected to a socket-outlet. Therefore,
provision should not be made for dimming function in fixed and portable socket-outlets.

6 Ratings
IEC 60884-1:2022, Clause 6 is applicable except as follows:
Addition at the end:
The rated voltage of the accessory shall be selected by the manufacturer according to the
nominal voltage of the fixed electrical installation where the accessory is intended to be installed
or used.
The rated current of the accessory shall be the lowest value of the following:
– the rated current of the plug and socket-outlet system;
– the rated current of the incorporated overcurrent protection, if any.
NOTE Examples of incorporated overcurrent protection are cut-outs, fuses, etc.
The preferred rated supply frequencies are 50 Hz and 60 Hz.
Compliance is checked by inspection of the marking.
7 Classification
IEC 60884-1:2022, Clause 7 is applicable except as follows:
Additional subclauses:
7.101 Classification according to the type of additional function
7.101.1 Accessories incorporating electronic components for additional functions that control
the output of the accessory (ECF)
7.101.2 Accessories incorporating electronic components for additional functions being
powered by the accessory which do not control the output (EPF)
7.101.3 Accessories incorporating electronic components for additional functions that operate
as a protection means (EPM)
NOTE Accessories can contain one or more types of additional functions.
7.102 Classification according to the connection to the network port based on SELV
7.102.1 connected to a network which is installed wholly within the same equipotential earthing
system;
7.102.2 connected to a network which is not installed wholly within the same equipotential
earthing system
8 Marking
IEC 60884-1:2022, Clause 8 is applicable except as follows:
8.1 General
Add a new dash after the second dash:
– rated power in watts, if applicable;
Addition after NOTE 2 of the following:
The rating of power in watts shall be marked when the rated current value is lower than the
value of the plug and socket-outlet system as given in the standard sheet.
The rated power is calculated using the nominal voltage of the fixed electrical installation in
volts, the rated current in amperes and a power factor cos ϕ = 1.
In addition, accessories shall be marked with:
– rated frequency in Hertz for fixed accessories, unless the accessory is designed for both
50 Hz and 60 Hz;
– rating and type of any fuse incorporated in the accessory, if intended to be replaceable.
