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 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
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.
International Standard IEC 61076-1 has been prepared by subcommittee 48B: Connectors, of
IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
This second edition cancels and replaces the first edition issued in 1995, its amendment 1
(1996) and its amendment 2 (2001) and constitutes a technical revision. Modifications with
respect to the previous edition are described in the introduction.
This standard is to be used in conjunction with IEC 62197-1:2006.

INTRODUCTION
The objective of this work is to update the quality assessment procedures of the connector
specifications to the current state of the art industrial procedures.
At the time of publication, all the connector detail specifications dealt with by subcommittee
48B of the International Electrotechnical Commission were built as described in Figure 1 with
5 major chapters.
The most significant out of date procedures relate to the lot-by-lot tests with different
inspection levels and acceptance quality level and to the periodic tests with permitted number
of defectives.
It was felt necessary to introduce the capability and the technology approval together with the
basic design parameters of statistical process control as a feed back system to have a
continuous control of the quality during the various steps of manufacture.
It was also felt appropriate to split the current documentation structure into two separate
structures of documents which, in the day to day use of specifications, satisfy most users, see
Figure 2.
The documentation system will be split into two parts:
• Product requirements
• Quality assessment requirements
The structure for the Product Specification contains characteristics, dimensions, performance
requirements and test schedules.
The structure for the quality assessment specification contains the requirements to obtain
Qualification Approval (QA) for a given performance level (per environment category),
Capability Approval (CA) per family of connectors or Technology Approval (TA) comprising all
relevant technologies for connector production.
Capability Approval or Technology Approval combined with statistical process control
parameters are intended to replace lot-by-lot and periodic tests.
To fully certify a product, a combination of the two structures will have to be selected by the
user, keeping in mind that in the statistical process control, key characteristics shall be
agreed between manufacturer and user.
A generic product specification with a 4 level structure consists of a generic, a sectional, a
blank detail and a detail specification.
From this, it can be concluded that two generic specifications are being circulated, one
document for the product aspects and a second one for the quality aspects.
The sectional specifications will be presented at the product level per family of connectors, for
example printed board connectors, circular connectors, rectangular connectors, etc.

nd
The objective of this 2 Edition is to review and update the actual connector specifications
containing product and quality assessment requirements.
Today, all the connector detail specifications dealt with by Subcommittee 48B of the
International Electrotechnical Commission are prepared as described in figure 1 with 5 major
chapters.
The most significant out of date procedures relate to the lot-by-lot tests with different
inspection levels and acceptance quality level and to the periodic tests with permitted number
of defectives.
To update the document to reflect modern practices it was necessary to introduce the
capability and the technology approval together with the basic design parameters of statistical
process control as a feed back system to have a continuous quality control during various
steps of manufacture.
It was also felt appropriate to split the current documentation into two separate structures of
documents which, in the day-to-day use of specifications, satisfy most users, see illustration
in Figure 2.
This offers the user the option to acquire products with and without certification. It is obvious
that the industry needs to get separate information on dimensions, performance requirements
and basic design parameters.
The two separate documents are:
▪ Product requirements
▪ Quality assessment requirements
The Product Specification contains characteristics, dimensions, performance requirements
and test schedules. The relevant document is:
IEC 61076-1 (Ed. 2)
Connectors for electronic equipment – Product requirements –
Part 1: Generic Specification.
The Quality Assessment Specification contains the requirements to obtain Qualification
Approval (QA) for a given performance level (per environment category), Capability Approval
(CA) per family of connectors or Technology Approval (TA) comprising all relevant
technologies for connector production.
Capability Approval or Technology Approval combined with statistical process control
parameters are intending to replace lot-by-lot and periodic tests. The relevant document is:
IEC 62197-1
Connectors for electronic equipment – Quality assessment requirements –
Part 1: Generic Specification
To specify a fully certified product, a combination of specifications from both structures shall
be required.
The 4 level document structure adopted by SC48B consists of a Generic, a Sectional, a Blank
Detail and Detail Specifications.

---------------------- Page: 13 ----------------------

61076-1  IEC:2006 – 17 –
To maintain this 4 level structure, two Generic Specifications are being circulated, one
document for the product aspects and a second one for the quality aspects.
The Sectional Specifications will be presented at the product level per family of connectors
e.g. printed board connectors, circular connectors, rectangular connectors, etc.
At the quality assessment level Annex B of IEC 62197-1 is dealing with Qualification Approval
B.2, Capability Approval B.3 and Technology Approval B.4.

1 General
1.1 Scope
This part of IEC 61076 establishes uniform specifications and technical information for
connectors.
This part of IEC 61076 is applicable to a family of connectors for use in electronic and
electrical equipment; connectors designed for use at radio frequencies are not covered.
1.2 General considerations relating to specifications
This part of IEC 61076 contains, or gives reference to, the terms, definitions, symbols, test
schedules and information relating to connectors.
It shall be used in conjunction with IEC Guide 109 that advocates the need to minimise the
impact of a product on the natural environment throughout the product life cycle.
It is understood that some materials permitted by this specification and in manufacturing and
assembly processes may have a negative environmental impact. As technological advantages
lead to acceptable alternatives for these materials, they shall be eliminated from this
specification. Inappropriate manufacturing processes should be replaced by a product design
that features easy maintainability and disassembly.
In the event of conflict between this part of IEC 61076 and the sectional product specification,
the requirements of the sectional product specification prevail.
1.2.1 Sectional product specifications
All details appropriate to a particular subfamily of connectors are contained in the relevant
sectional product specification, for example printed board, circular, rectangular connectors
and other connecting devices.
It shall contain a choice of all test methods and sequences, severities and preferred values
for dimensions and characteristics, which could be applicable to that subfamily.
The contents shall be derived from IEC 61076-1.
In the event of conflict between a Sectional Product Specification and the Detail Product
Specification, the requirements of the Detail Product Specification shall prevail.
