Devices for the connection of luminaires
for household and similar purposes -
Part 1: General requirements
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.
IEC 61995-1 has been prepared by subcommittee 23B: Plugs, socket-outlets and switches, of
IEC technical committee 23: Electrical accessories. It is an International Standard.
This second edition cancels and replaces the first edition published in 2005 and
Amendment 1:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) additional requirements and tests for additional suspension means;
b) additional requirements and tests for additional functions;
c) additional requirements and tests for floating type DCLs;
d) introduction of insulation piercing terminals (IPT);
e) additional classification according to the connection capacities of the DCL outlet terminals;
IEC 61995-1:2025 © IEC 2025
f) modification of maximum withdrawal force for plugs with enabled locking means;
g) improvements of temperature rise tests.
The text of this International Standard is based on the following documents:
Draft Report on voting
23B/1573/FDIS 23B/1581/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
A list of all the parts in the IEC 61995 series, published under the general title Devices for the
connection of luminaires for household and similar purposes, can be found on the IEC website.
In this document, the following print types are used:

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or

1 Scope
This document applies to devices for the connection of luminaires (DCL) intended for household
and similar purposes, for the electrical connection of fixed luminaires of class I or class II to
final circuits rated at not more than 16 A without mechanical support for the luminaires
incorporated in the plug/outlet interface. The DCL retention mechanisms are not intended to
support the weight of the luminaires.
• DCL plugs and outlets have a rated current of 6 A.
• DCL outlets have an earthing contact.
The rated voltage is 125 V or 250 V at 50/60 Hz.
• DCLs with additional suspension means are limited to a maximum mass of 5 kg.
• DCL plugs and DCL outlets complying with this document are suitable for use at ambient
temperatures not normally exceeding +40 °C, but their average over a period of 24 h does
not exceed + 35 °C, with a lower limit of the ambient air temperature of −5 °C.
• DCLs are intended for use according to their IP rating as specified in IEC 60529.
This document gives additional requirements for DCL accessories provided with
insulation-piercing terminals, see Annex B (normative).
