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

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) 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.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 61995-1 edition 1.1 contains the first edition (2005-03) [documents 23B/776/FDIS and
23B/782/RVD] and its amendment 1 (2016-05) [documents 23B/1208/FDIS and 23B/1212/RVD].

relevant part 2.
Compliance is checked by measurement and/or by means of gauges.
9.2 DCL types classified according to 7.1 b) as other types shall comply with the relevant
specification and shall not be interchangeable with or create a hazardous situation with DCL
types complying with the standard sheets of part 2.
Compliance is checked by measurement and/or by means of gauges.
10 Protection against electric shock
10.1 DCL outlets shall be so designed that, when they are wired and mounted as for normal
use, live parts are not accessible, even after removal of parts which can be removed without
the use of a tool.
Live parts of DCL plugs shall not be accessible when the DCL plug is in partial or complete
engagement with a DCL outlet.
Compliance is checked by inspection and, if necessary, by the following test:
The specimen is mounted as for normal use and fitted with conductors of the smallest cross-
sectional areas and the test is then repeated using conductors of the largest cross-sectional
areas, as specified in Table 1.
For DCL outlets, the test finger specified in IEC 61032 test probe B is applied in every
possible position.
– 14 – IEC 61995-1:2005+AMD1:2016 CSV
IEC 2016
For DCL plugs, the test finger is applied in every possible position when the plug is in partial
or complete engagement with a DCL outlet.
An electrical indicator with a voltage of (45 ± 5) V, is used to show contact with the relevant
part.
For DCL systems where the use of elastomeric or thermoplastic material is likely to influence
the requirement, the test is repeated but at an ambient temperature of (35 ± 2) °C, the DCLs
being at this temperature.
During this additional test the DCLs are subjected for 1 min to a force of 75 N, applied
through the tip of a straight unjointed test finger of the same dimensions as the standard test
finger. This finger, with an electrical indicator as described above, is applied to all places
where yielding of the insulating material could impair the safety of the accessory, and it is
applied to thin walled knock-outs with a force of 10 N.
During this test, the DCL, with its associated mounting means, shall not deform to such an
extent that those dimensions shown in the relevant standard sheets which ensure safety are
unduly altered and no live part shall be accessible.
10.2 Parts which are accessible when the DCL is wired and mounted as for normal use,
with exception of small screws and the like, isolated from live parts, for fixing bases and
covers or cover plates of DCL outlets, shall be made of insulating material; however the
covers or cover-plates of fixed DCL outlets may be made of metal if the requirements given in
10.2.1 or 10.2.2 are fulfilled.
10.2.1 The covers or cover-plates of metal shall be protected by supplementary insulation
made by insulating linings or insulating barriers fixed to covers or cover-plates or to the body
of the DCL, in such a way that the insulating linings or insulating barriers:
– either cannot be removed without being permanently damaged,
– or are so designed that:
– they cannot be replaced in an incorrect position;
– if they are omitted, the DCLs are rendered inoperable or manifestly incomplete;
– there is no risk of accidental contact between live parts and metal covers or cover-
plates, for example through their fixing screws, even if a conductor should come away
from its terminal;
– precautions are taken in order to prevent creepage distances or clearances becoming
less than the values specified in Clause 25.
Compliance is checked by inspection.
The above linings or barriers shall comply with the tests of Clauses 16 and 25.
NOTE Insulating coating sprayed on the inside or on the outside of the metal covers or cover plates is not
deemed to be an insulating lining or barrier for the purpose of this requirement.
10.2.2 The metal covers or cover-plates shall be securely connected, through a low
resistance connection, to the earth during fixing of the cover or the cover-plate itself.
NOTE 1 Fixing screws of metal covers, cover-plates or other means are allowed.
The creepage distances and the clearances between the live pins of a DCL plug when fully
inserted and the earthed metal cover of a DCL outlet shall comply with items 2 and 7 of Table
14 respectively.
Compliance is checked by inspection and by the test of 11.4.
IEC 2016
NOTE 2 Due to the lack of an earthing conductor in many existing old buildings, accessories requiring earth
connection cannot normally be used in the following countries: DK.
10.3 It shall not be possible to make connection between a pin of a DCL plug and a live
contact of a DCL outlet while any other pin is accessible.
Compliance is checked by manual test using a DCL outlet with corresponding DCL plug and
test finger specified in IEC 61032 test probe B in a manner most likely to make contact with
live parts. In applying the test a supply of (45 ± 5) V, in series with a suitable indicating lamp,
shall be connected between the test finger and the relevant conducting parts of the DCL plug
and/or DCL outlet.
For DCLs with enclosures or bodies of thermoplastic material, the test is made at an ambient
temperature of (35 ± 2) °C, both the DCL and the gauge being at this temperature.
For DCL outlets provided with metal covers or cover plates, a clearance, between a pin and a
socket-contact, of at least 2 mm is required, when another pin, or pins, is (are) in contact with
the metal covers or cover-plates.
10.4 External parts of DCL plugs, with the exception of assembly screws and the like,
current-carrying and earthing pins, earthing straps and metal rings around pins, shall be of
insulating material. Covers of DCL plugs may be of metal provided they comply with the
requirements of 10.2.1 or 10.2.2.
Compliance is checked by inspection.
NOTE Lacquer, enamel or sprayed insulating coating is not deemed to be insulating material for the purpose of
10.1 to 10.4.
11 Provision for earthing
11.1 DCLs with earthing contact shall be so constructed that, when inserting the DCL plug,
the earth connection is made before the current-carrying contacts of the DCL plug become
live.
When withdrawing the DCL plug, the current-carrying pins shall not remain live after the earth
connection is broken.
Compliance is checked by inspection and by measurement.
11.2 Earthing terminals of rewirable DCLs shall allow the proper connection of copper
conductors in accordance with Clause 12.
11.3 Accessible metal parts of DCL outlets, which may become live in the event of an
insulation fault, shall be permanently and reliably connected to the earthing terminal.
NOTE 1 This requirement does not apply to the metal cover or cover-plates complying with 10.2.1.
NOTE 2 For the purpose of this requirement, small screws and the like, isolated from live parts, for fixing bases,
covers or cover-plates, are not considered as accessible parts which may become live in the event of an insulation
fault.
Compliance with the requirements of 11.2 to 11.3 is checked by inspection and by the tests of
