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.

1 Scope
This part of IEC 61076 establishes uniform specifications and technical information for circular
connectors. This document is to be used in conjunction with the generic specification
IEC 61076-1 for product requirements as the basis for preparation of detail product
specifications for circular connectors.
NOTE The quality assessment requirements for connectors whose product requirements are given in IEC 61076
series are detailed in IEC 62197-1. This can be used as the basis for preparation of detail quality assessment
specifications for circular connectors.
In the event of conflict between this sectional product specification and the detail product
specification, it is intended that the requirements of the detail product specification prevail.
2 Normative references

4 Technical information
4.1 System of levels
4.1.1 General
Subclauses 4.1.2 and 4.1.3 provide information about performance and compatibility levels
(respectively).
4.1.2 Performance levels
If appropriate, the detail product specification shall contain information about the different
performance levels.
The term 'performance level' reflects the grouping of the environmental and mechanical
stresses at which a component is tested, and also such features as long-term stability of
electrical characteristics. If different levels are defined in the detail product specification, they
shall be numbered, where the lowest number (1) usually indicates the highest performance.
4.1.3 Compatibility levels
As a function of the standardization degree, four levels characterize the compatibility of
connectors from different sources. These levels are defined in IEC 61076-1 and shall be
indicated in the detail product specification of circular connectors.
4.2 Classification into climatic categories
Unless impractical, the lower and upper temperatures and the duration of the damp heat, steady
state test should be described in a table similar to the example given in IEC 61076-1.
For a correct assignment of climatic category, the correct relationship between the upper
category temperature (UCT) and the upper limiting temperature (ULT) of a connector (implied
in the derating diagram(s) discussed in 4.4), as well as between the lower category temperature
(LCT) and the lower limiting temperature (LLT) of a connector should be considered (see
IEC 61984 relevant definitions).
4.3 Clearance and creepage distances
Permissible working or rated voltages depend on the connector end-use application and on the
applicable or specified safety requirements.
Clearance and creepage distances as well as proof voltages under specified air pressure shall
be specified in the detail product specification, based on the assigned rated insulation
voltage(s). See IEC 61984, IEC 60664-1 or IEC TR 63040, as applicable.
4.4 Current-carrying capacity
For each connector, the current-carrying capacity for the declared wire size (typically the
maximum) shall be specified in the detail product specification. It is preferable that the derating
curve for the relevant wire size, determined in accordance with test 5b of IEC 60512-5-2 is
prepared. Alternatively, it is allowed to provide only one value of rated current for a specified
wire size at a specified temperature as described in IEC 60512-5-1.
NOTE 1 The derating curve(s) can be provided in either graphic form or in mathematical form with the formula or
both:
0,5
t

II ×−1

where
I = working current at ambient temperature t;

(t)
I = working current at 0 °C (intersection with y-axis);

(0 °C)
t = ambient temperature;
ULT = upper limiting temperature (intersection with x-axis ≥ UCT (upper category temperature)
NOTE 2 The basic diagram determined in accordance with test 5b of IEC 60512-5-2 is then verified by a
temperature rise test 5a of IEC 60512-5-1
4.5 Marking
Each connector and its associated package shall be marked in accordance with the
requirements specified in IEC 61076-1.
5 Dimensional information

of materials, as applicable, shall be provided by detail product specification.
7 Tests and test schedules
7.1 General aspects
See IEC 61076-1.
The detail product specification shall state the test sequence(s) (in accordance with this
standard), and the number of specimens for each test sequence (not less than four mated
pairs).
Individual variants may be submitted to type tests for approval of those 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
product specification), but each feature and characteristic shall be proved.
The test specimens shall have been processed in a careful and skilful manner, in accordance
with good current practice.
NOTE When the preparation of test specimens involves wiring with a solderless connection technology, the relevant
part of IEC 60352 series includes practical guidance which serves as a benchmark for the level of skill. Wiring of
specimens implying the use of special processes or tools Is up to the connector manufacturer.
7.2 Test schedules
7.2.1 General
To provide for different applications of connectors, the extent of the test schedule may be
different in the various detail product specifications.
The basic (minimum) test schedule is given in 7.2.2.

4 Données techniques
4.1 Système de niveaux
4.1.1 Généralités
Les paragraphes 4.1.2 et 4.1.3 donnent des informations sur les niveaux de performances et
de compatibilité (respectivement).
4.1.2 Niveaux de performances
Le cas échéant, la spécification particulière de produit doit contenir des informations sur les
différents niveaux de performance.
Le terme "niveau de performance" correspond au regroupement des contraintes
environnementales et mécaniques subies par un composant au cours de ses essais et aussi à
des caractéristiques comme la stabilité à long terme des caractéristiques électriques.
Si différents niveaux sont définis dans la spécification particulière de produit, ceux-ci doivent
être numérotés, le chiffre le moins élevé (1) indique généralement la performance la plus
élevée.
4.1.3 Niveaux de compatibilité
En fonction du degré de normalisation, quatre niveaux caractérisent la compatibilité de
connecteurs provenant de sources différentes. Ces niveaux sont déjà définis
dans l’IEC 61076-1 et ils doivent être indiqués dans la spécification particulière de produit des
connecteurs circulaires.
4.2 Classification en catégories climatiques
Sauf impossibilité pratique, il convient que les températures inférieure et supérieure, ainsi que
la durée de l’essai continu de chaleur humide soient données dans un tableau comme celui
donné en exemple dans l’IEC 61076-1.
Pour une attribution correcte de la catégorie climatique, la relation correcte entre la température
haute de la catégorie climatique (THC) et la température limite supérieure (ULT, Upper Limiting
Temperature) d’un connecteur (impliquée dans la ou les courbes de réduction mentionnées
en 4.4), ainsi qu’entre la température basse de la catégorie climatique (TBC) et la température
limite inférieure (LLT, Lower Limiting Temperature) d’un connecteur, voir les définitions
pertinentes de l’IEC 61984.
4.3 Distances d’isolement et lignes de fuite
Les tensions de travail ou assignées admissibles dépendent de l’application finale du
connecteur et des exigences de sécurité applicables ou spécifiées.
Les distances d’isolement et les lignes de fuite, ainsi que les tensions d’essai sous une pression
atmosphérique spécifiée, doivent être stipulées dans la spécification particulière de produit, en
se basant sur la tension d’isolement assignée spécifiée. Voir l’IEC 61984, l’IEC 60664-1 ou
l’IEC/TR 63040, suivant le cas.
4.4 Courant admissible
Pour chaque connecteur, le courant admissible pour le diamètre du fil déclaré (généralement
la valeur maximale) doit être stipulé dans la spécification particulière de produit. Il est préférable
de préparer la courbe de réduction pour le diamètre du fil approprié, déterminée conformément
à l’essai 5b de l’IEC 60512-5-2. En variante, il est admis de fournir une seule valeur de courant
assigné pour un diamètre du fil spécifié et une température spécifiée comme décrit
dans l’IEC 60512-5-1.
NOTE 1 La ou les courbes de réduction peuvent être fournies soit sous forme graphique, soit sous forme
mathématique avec la formule suivante, ou les deux à fois:
0,5
t
II ×−1

(t) (0 °C)
ULT


I = courant de travail à température ambiante t;

(t)
I = courant de travail à 0 °C (intersection avec l’axe x);

(0 °C)
t = température ambiante;
ULT = température limite supérieure (intersection avec l’axe x ≥ THC (température haute de la catégorie
climatique)).
NOTE 2 La courbe de base déterminée conformément à l’essai 5b de l’IEC 60512-5-2 est ensuite vérifiée par un
essai d’échauffement 5a de l’IEC 60512-5-1.

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 61076-2 has been prepared by subcommittee 48B: Electrical connectors, of IEC technical

1 Scope
This part of IEC 61076 establishes uniform specifications and technical information for circular
connectors. This document is to be used in conjunction with the generic specification
IEC 61076-1 for product requirements as the basis for preparation of detail product
specifications for circular connectors.
NOTE The quality assessment requirements for connectors whose product requirements are given in IEC 61076
series are detailed in IEC 62197-1. This can be used as the basis for preparation of detail quality assessment
specifications for circular connectors.
In the event of conflict between this sectional product specification and the detail product
specification, it is intended that the requirements of the detail product specification prevail.

4 Technical information
4.1 System of levels
4.1.1 General
Subclauses 4.1.2 and 4.1.3 provide information about performance and compatibility levels
(respectively).
4.1.2 Performance levels
If appropriate, the detail product specification shall contain information about the different
performance levels.
The term 'performance level' reflects the grouping of the environmental and mechanical
stresses at which a component is tested, and also such features as long-term stability of
electrical characteristics. If different levels are defined in the detail product specification, they
shall be numbered, where the lowest number (1) usually indicates the highest performance.
4.1.3 Compatibility levels
As a function of the standardization degree, four levels characterize the compatibility of
connectors from different sources. These levels are defined in IEC 61076-1 and shall be
indicated in the detail product specification of circular connectors.
4.2 Classification into climatic categories
Unless impractical, the lower and upper temperatures and the duration of the damp heat, steady
state test should be described in a table similar to the example given in IEC 61076-1.
For a correct assignment of climatic category, the correct relationship between the upper
category temperature (UCT) and the upper limiting temperature (ULT) of a connector (implied
in the derating diagram(s) discussed in 4.4), as well as between the lower category temperature
(LCT) and the lower limiting temperature (LLT) of a connector should be considered (see
IEC 61984 relevant definitions).
4.3 Clearance and creepage distances
Permissible working or rated voltages depend on the connector end-use application and on the
applicable or specified safety requirements.
Clearance and creepage distances as well as proof voltages under specified air pressure shall
be specified in the detail product specification, based on the assigned rated insulation
voltage(s). See IEC 61984, IEC 60664-1 or IEC TR 63040, as applicable.
4.4 Current-carrying capacity
For each connector, the current-carrying capacity for the declared wire size (typically the
maximum) shall be specified in the detail product specification. It is preferable that the derating
curve for the relevant wire size, determined in accordance with test 5b of IEC 60512-5-2 is
prepared. Alternatively, it is allowed to provide only one value of rated current for a specified
wire size at a specified temperature as described in IEC 60512-5-1.
NOTE 1 The derating curve(s) can be provided in either graphic form or in mathematical form with the formula or
both:
0,5


II ×−1
t 0 °C 
() ( )
ULT

where
I = working current at ambient temperature t;

(t)
I = working current at 0 °C (intersection with y-axis);

(0 °C)
t = ambient temperature;
ULT = upper limiting temperature (intersection with x-axis ≥ UCT (upper category temperature)
NOTE 2 The basic diagram determined in accordance with test 5b of IEC 60512-5-2 is then verified by a
temperature rise test 5a of IEC 60512-5-1
4.5 Marking
Each connector and its associated package shall be marked in accordance with the
requirements specified in IEC 61076-1.

7 Tests and test schedules
7.1 General aspects
See IEC 61076-1.
The detail product specification shall state the test sequence(s) (in accordance with this
standard), and the number of specimens for each test sequence (not less than four mated
pairs).
Individual variants may be submitted to type tests for approval of those 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
product specification), but each feature and characteristic shall be proved.
The test specimens shall have been processed in a careful and skilful manner, in accordance
with good current practice.
NOTE When the preparation of test specimens involves wiring with a solderless connection technology, the relevant
part of IEC 60352 series includes practical guidance which serves as a benchmark for the level of skill. Wiring of
specimens implying the use of special processes or tools Is up to the connector manufacturer.
7.2 Test schedules
7.2.1 General
To provide for different applications of connectors, the extent of the test schedule may be
different in the various detail product specifications.
The basic (minimum) test schedule is given in 7.2.2.
The detail product specification shall state the tests to be carried out and shall specify the
requirements to be fulfilled.
In no case shall the tests required by the detail product specification be less than those listed
in 7.2.2.
A full test schedule is described in 7.2.3. This should be used to evaluate connectors deemed
to be employed in severe environments (e.g. aircraft or marine environments).
For most connector types, an intermediate test schedule can be appropriate. This intermediate
test schedule shall then be formed by omitting either entire groups or conditionings or both from
the full test schedules that are not necessary.
Test phase numbers shall not be modified but used as given in 7.2.3 with additional words "not
applicable".
The same is applicable when the sequence of the test phases in a test group is not entirely
appropriate to a particular type or style. In that case, the sequence of the tests, but not the
measurement to be performed may be altered for that particular detail product specification.
The test phase number shall be retained the additional wording "not applicable", for each test
thereby affording clarity should such alteration in sequence be conducted.
Where a detail product specification includes additional characteristics which require either
testing or specific test sequences, or both, the appropriate existing or new test (in the form of
a normative annex to the detail product specification) shall be in the appropriate place in the
test table. These may be specified in an additional test group or groups.
It is necessary for the detail product specification to select the appropriate basic, intermediate
or full test schedule.
7.2.2 Basic (minimum) test schedule
Where the basic (minimum) test schedule is appropriate, the detail product specification shall
call for the following tests listed in Table 1 and shall specify the characteristics to be examined
and the requirements to be fulfilled.

7.2.3.1 General
Where the full test schedule is appropriate, the detail product specification shall call for the
following tests (Table 2 to Table 13) and shall specify the characteristics to be examined and
the requirements to be fulfilled.
The schedule detailed below is recommended for preparing detail product specifications,
however, specific design and application features shall carefully be taken into account when
preparing the detail product specification. The schedule detailed below shall be used as a guide.
The test phase numbering should be used as specified below.
To comply with the different applications of connectors, the test schedule of the detail product
specifications may be extended to provide performance for different fields of application.
For solderless terminations, test sequences of the applicable part of IEC 60352 shall be
integrated into the appropriate full test schedule.
