Overview

EN IEC 63138-1:2019 (IEC 63138-1:2019) is a generic specification that sets out the general requirements and test methods for multi‑channel radio‑frequency (RF) connectors. Published by CLC/CENELEC and identical to the IEC edition, this standard provides the foundation for sectional specifications for different multi‑channel RF connector types used in communications, electronics and other equipment. It covers terminology, design and construction, ratings and characteristics, climatic categories, IEC type designation, test procedures, quality assessment and marking.

Key topics and technical requirements

The standard defines mandatory and recommended practices across several technical areas:

  • Terms and definitions relevant to multi‑channel RF connectors (ensures consistent vocabulary).
  • Design and construction: materials, finishes, interface and RF channel dimensions, mechanical compatibility and outline dimensions.
  • Standard ratings and characteristics: electrical and mechanical ratings to be declared in sectional specifications.
  • Climatic categories: preferred environmental categories referencing IEC 60068‑1 for selection of test severities.
  • IEC type designation: standardized marking and identification rules.
  • Requirements and test methods, including:
    • Visual inspection and dimensional / interchangeability checks.
    • Electrical tests: return loss, insertion loss, contact resistance, insulation resistance, voltage proof, screening effectiveness, discharge tests, passive intermodulation (PIM), isolation and RF power rating (where applicable).
    • Mechanical tests: solderability, contact/ channel captivation, engagement/disengagement forces, retention, cable-pull, bending, torsion, coupling strength, vibration (low/high frequency), shock and mechanical endurance.
    • Environmental tests: damp heat, thermal shock, high/low temperature endurance, leakage/ hermeticity and salt mist.
  • Quality assessment: qualification, lot-by‑lot and periodic inspection plans and sampling procedures.
  • Marking and packaging: marking of components and packaged contents.

Applications and who uses this standard

EN IEC 63138-1 is intended for manufacturers, test labs, product engineers and procurement teams involved with multi‑channel RF connectors, including:

  • Connector designers and component manufacturers (for product development and compliance).
  • Test laboratories (to perform standardized electrical, mechanical and environmental testing).
  • OEMs and systems integrators in telecommunications, broadcast, aerospace, defense and industrial electronics (for supplier specifications and acceptance testing).
  • Standards committees and product spec writers (as a basis for sectional and detail specifications).

Practical benefits include enabling connector interchangeability, reliable RF performance (return/insertion loss, isolation, low PIM), environmental robustness and consistent quality assurance.

Related standards

  • IEC 61169‑1 (RF connectors – generic specification)
  • IEC 60068 series (environmental testing)
  • IEC 62037‑3 (passive intermodulation measurement) These referenced standards provide complementary test methods and environmental categories referenced by EN IEC 63138‑1.

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.

7 IEC type designation
The purpose of the IEC type designation is to identify a particular connector within the scope of
IEC RF connector standardization. It is not intended to include information in excess of this.
In practice, it is usually necessary to identify a manufacturer's product because, although it
may comply with this document, there may be features that are not covered by this document.
Connectors complying with the relevant specification shall be designated by the following
indications and in the order given:
a) the number of this document;

IEC 63138-1:2019 © IEC 2019 – 9 –
b) the letters "IEC";
c) series code (type designation);
d) additional identification as indicated in the relevant specification.
NOTE When an IEC type designation is used, either for the marking of the product or in a description of the product,
it is the responsibility of the manufacturer to ensure that the item meets the requirements of the relevant
specification.
8 Requirements and test methods
8.1 General
Unless otherwise specified, the following conditions shall apply:
a) tests shall be carried out under standard atmospheric conditions for testing as specified in
IEC 60068-1;
b) before measurements are made, the connectors shall be preconditioned under standard
atmospheric conditions for testing for a time sufficient to allow the entire connector to reach
thermal stability;
c) recovery conditions for the interval after a conditioning and the next measurement of the
test shall be in accordance with IEC 60068-1.
When a nominal value only is given for an applied stress and/or the duration of application, the
specified value shall be taken to indicate the minimum test severity to be applied.
In no case shall the contact parts be cleaned or otherwise prepared prior to tests, unless
explicitly stated in the relevant specification.
If it is required that a cable be attached to an RF contact of the connector, this shall be done in
accordance with the connector manufacturer's instructions.
Mated sets of connectors shall be fully engaged and screw-coupled connectors shall be
tightened to the normal coupling torque quoted in the relevant specification.
In the case of mounted connectors subjected to environmental conditioning, care shall be taken
to ensure that the back-of-panel portion of such fixed connectors, when appropriate, is
protected.
When using for tests involving exposure to extreme temperatures, a cable with appropriate
temperature capability should be used.
8.2 Visual inspection
8.2.1 Requirements
Visual inspection shall meet the following requirements:
a) Marking
Marking shall be in compliance with 10.1 and be legible after any of the specified tests.
b) Workmanship
Connectors and associated fittings shall be processed in such a manner as to be uniform in
quality and shall be free from visible sharp edges, burrs and other defects that will affect life,
serviceability or appearance.
c) Deterioration after electrical, mechanical and environmental tests

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.
