Part 2-2: Particular requirements –
Connectors for LED-modules
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 IEC 60838-2-2 consists of the first edition (2006)
[documents 34B/1229/FDIS and 34B/1237/RVD] and its amendment 1 (2012) [documents
34B/1621/CDV and 34B/1638/RVC]. It bears the edition number 1.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

– 4 – 60838-2-2  IEC:2006+A1:2012
International Standard IEC 60838-2-2 has been prepared by subcommittee 34B: Lamp caps
and holders, of IEC technical committee 34: Lamps and related equipment.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-2 is to be used in conjunction with the latest edition of IEC 60838-1 and its
amendments. It was established on the basis of the fourth edition (2004) of that standard.
IEC 60838 consists of the following parts, under the general title Miscellaneous lampholders:
Part 1: General requirements and tests
Part 2-1: Particular requirements – Section 1: Lampholders S14
Part 2-2: Particular requirements – Connectors for LED modules
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the stability 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.
IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

16 Endurance
The requirements of Clause 15 of IEC 60838-1 apply together with the following additions.
16.1 Connectors for LED modules shall be capable of maintaining good electrical contact to
the module during rapid change of temperature.
Compliance is checked by the following test.
A commercial LED module or capped printed circuit board in accordance with IEC 60061, if
existing, is inserted and the resistance of the connector contacts and connections is
measured as mentioned in 16.3.
The connector and module is then subjected to the temperature change test in accordance to
IEC 60068-2-14, test Na, subject to the following details.
The specimen shall be subjected to 100 cycles between the minimum and the maximum value
of the rated operating temperature range. The exposure time of each of the two temperatures
is 30 min.
NOTE Standard transition time is between 2 min and 3 min. A transition time (t ) of less than 30 s is allowed, if an
automatic test system is used.
During the test the connector shall not undergo any change impairing its further use,
especially with respect to contact-making.
After the temperature change test the connector is removed from the test chamber and
allowed to recover for 12 h. The LED module remains inserted during this time. The
resistance of the connector contacts and connections as mentioned in 16.3 is measured again
with the above configuration.
– 8 – 60838-2-2  IEC:2006+A1:2012
16.2 Connectors for LED modules shall be capable to maintain good electrical contact to the
module in high humidity environment.
Compliance is checked by the following test.
A commercial LED module or capped printed circuit board in accordance with IEC 60061, if
existing, is inserted and the resistance of the connector contacts and connections is
measured as mentioned in 16.3.
The connector and module is then subjected to the damp heat test, cyclic, in accordance to
IEC 60068-2-30, subject to the following details.
The specimen shall be subjected to 6 cycles at maximum temperature 55°C, variation 2.
During the test the connector shall not undergo any change impairing its further use,
especially with respect to contact-making.
After the damp heat test the connector is removed from the test chamber and allowed to
recover for 12 h. The LED module remains inserted during this time. The resistance of the
connector contacts and connections as mentioned in 16.3 is measured again with the above
configuration.
16.3 The resistance of the connector contacts and connections is measured as follows:
– a current equal to the rated current of the connector is allowed to flow for a time just
sufficient for the resistance to be measured;
– on connectors equipped with leads, the resistance is measured between the leads 5 mm
from where they come out of the connector;
– on connectors without leads, it is necessary to attach leads of the minimum size for which
the connector was designed. The resistance is measured between the leads 5 mm from
where they come out of the connector;
The measurement is made in an a.c. circuit of not more than 6V.
The measured resistance shall not exceed the following value:
0,045 Ω + (A × n)
