FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61076-3 has been prepared by subcommittee 48B: Connectors, of

2 Technical information
The detail specification shall contain information which contributes to a proper application of
the connectors. It will also provide specificities to enable a better understanding of the
connectors and/or the connector family.
2.1 Terminology
In addition to the terminology used in, and applicable to, the detail specification, as stated
in 2.1 of IEC 61076-1, it is recommended that those definitions which are unique to the
connectors specified in the detail specification be listed.
2.2 Classification into climatic categories
Unless impractical, the lower and upper temperatures and the duration for the damp heat,
steady-state test shall be described in a table similar to the example given in 2.2 of
IEC 61076-1.
2.3 Creepage and clearance distances
The detail specification shall specify creepage and clearance distances in accordance with
requirements of 2.3 of IEC 61076-1.
2.4 Current-carrying capacity

4.1 General
See clause 4 of IEC 61076-1.
The detail specification shall state the test sequence (in accordance with this standard), and
the number of specimens for each test sequence (not less than four).
Individual variants may be submitted to type tests for approval of those particular variants.
It is permissible to limit the number of variants tested to a selection representative of the
whole range for which approval is required (which may be less than the range covered by the
detail specification), but each feature and characteristic shall be proved.
The connectors shall have been processed in a careful and workmanlike manner, in
accordance with good current practices.

– 8 – 61076-3 © IEC:1999(E)
4.2 Test procedures and measuring methods
The test methods specified and given in the relevant standards are the preferred methods but
not necessarily the only ones which can be used. In case of dispute, however, the specified
method shall be used as the referee method.
Unless otherwise specified, all tests shall be carried out under standard atmospheric
conditions for testing as specified in IEC 60068-1.
Where approval procedures are involved and alternative methods are employed, it is the
responsibility of the manufacturer to satisfy the authority granting approval that any
alternative methods which he may use give results equivalent to those obtained by the
methods specified.
4.3 Pre-conditioning
Before the tests are made, the connectors shall be pre-conditioned under standard
atmospheric conditions for testing as specified in IEC 60068-1 for a period of 24 h unless
otherwise specified by the detail specification.
4.4 Wiring and mounting of specimens
4.4.1 Wiring
Where wiring of test specimens is required, the detail specification shall contain information
suitable to comply with the selected methods of test.
4.4.2 Mounting
When mounting is required in a test, unless otherwise specified, the connectors shall be
rigidly mounted on a metal plate, a printed board or to specified accessories, whichever is
applicable, using the normal mounting method, fixing devices and panel cut-out as laid down
in the detail specification.
4.5 Test schedules
To provide for different applications of connectors, the extent of the test schedule may be
different in the various detail specifications.
The basic (minimum) test schedule is given in 4.5.1.
The detail specification shall state the tests to be carried out and shall specify the
requirements to be fulfilled.
It is a requirement of this standard that in no case shall the tests required by the detail
specification be less than those listed in 4.5.1.
A full test schedule is laid down in 4.5.2.
For many connector types, an intermediate test schedule may be appropriate. Such
intermediate test schedule shall then be formed by using the full test schedule and omitting
entire groups and/or those tests and/or conditionings that are not necessary.
Test phase numbers shall not be modified but used as given in 4.5.2.
