EN IEC 61169-1-3:2026 is the CENELEC European Standard for radio-frequency connectors with built-in surge protective devices (SPD). It specifies electrical test methods, performance requirements and testing methods for coaxial-connector SPDs used on telecommunications and signalling networks to protect equipment from lightning-related and other transient overvoltages. It is written for manufacturers, test laboratories, and anyone specifying or verifying these connectors in practice.
What does EN IEC 61169-1-3:2026 specify?
EN IEC 61169-1-3:2026 applies to built-in SPD in coaxial connectors for surge protection of telecommunications and signalling networks. The document covers devices intended to protect electrical apparatus from transient overvoltages and divert surge currents, including gas discharge tube, ¼ wavelength short stub, flash-off gap, and hybrid types.
The scope places these built-in SPD in modern electronic equipment connected to networks with nominal system voltages up to 1 000 V AC and 1 500 V DC. In practice, that tells the reader which protection devices and network voltages are in scope for design, test and specification.
The document is organized into Clauses 1 to 7, followed by Annexes A, B and C for example measurement setups and Annex ZA for European normative references.
| Annex | What it covers |
|---|---|
| Annex A | Example equipment and layouts for DC sparkover voltage testing |
| Annex B | Example equipment and layouts for impulse sparkover voltage testing |
| Annex C | Example equipment and layouts for impulse durability testing |
What are the key requirements of EN IEC 61169-1-3:2026?
EN IEC 61169-1-3:2026 sets minimum electrical and test requirements for SPD built into coaxial connectors, and it links those requirements to specific test methods. The practical focus is on how the connector behaves before surge testing, during surge testing, and after surge testing.
Service and test conditions
Clause 4 defines the service environment and how tests are to be carried out. The standard distinguishes normal and abnormal service conditions, and it asks the manufacturer to consider abnormal conditions where they matter to the design or application.
For testing, Clause 4 allows a temperature of 23 °C ± 2 °C with controlled humidity only when the device technology is known to be insensitive to temperature for the characteristic under test. Otherwise, testing is done at the extreme temperatures relevant to the intended application, with gradual heating or cooling and enough time for thermal equilibrium. In practice, this means the test lab must choose the right climate condition for the device technology, not just a convenient room condition.
Clause 4 also says the SPD shall be tested with the same connections or terminations used in field installation. If a base or connector is part of the intended use, it is part of the test setup too. That matters because the result has to reflect real installation performance, not just the bare device.
Electrical performance before and after surge testing
Clause 5 treats all electrical requirements as minimum requirements, while allowing users to specify different values where needed. The initial sparkover voltage between connector terminals must meet the limits referenced from IEC 61643-311, and the specified return loss, insertion loss and insulation resistance are taken from the detail specification.
Clause 5 also requires impulse durability testing with a specified surge peak current applied a specified number of times. After that loading, the current-limiting element must still meet the detail specification. In practice, this checks that the SPD still performs its protective function after repeated surge stress.
After the impulse durability test, Clause 5 requires discharge inception voltage, return loss (VSWR), insertion loss and insulation resistance to remain within the ranges set for the connector. This is the key pass-fail point for users who need both surge protection and continued RF performance.
Test and measurement methods
Clause 6 gives the test methods for DC sparkover voltage, impulse sparkover voltage, impulse durability, return loss (VSWR), insertion loss and insulation resistance. For the sparkover tests, the GDT specimen is left in a dark place for at least 15 min before voltage is applied and the discharge inception voltage is measured using the circuits shown in the standard.
Clause 6 requires the impulse durability test to use the Figure 5 circuit arrangement, with further details referenced to IEC 61643-21:2025. It also states that return loss (VSWR) shall follow IEC 61169-1:2013, insertion loss shall follow IEC 61169-1-2, and insulation resistance shall follow IEC 61169-1:2013.
The measurement equipment must be suitable for the method used, and oscilloscopes must comply with IEC 61083-1. For users, this means the results depend not only on the specimen but also on the correctness of the test instrumentation and setup.
What has to be stated in the detail specification
Clause 7 requires the relevant specification to state the measurement range of sparkover voltage and the impulse durability levels. It also has to state any test fixture requirement and any difference from the test methods in this document.
That clause is important for procurement and quality control because it is where product-specific values, fixtures and deviations are fixed. Without those details, different suppliers could be testing to different assumptions.
What terms does EN IEC 61169-1-3:2026 define?
- Surge protective device (SPD) - A device that limits voltage at a designated port so the protected circuit sees less surge-induced overvoltage.
- Gas discharge tube (GDT) - A voltage-switching protective element used in some coaxial SPD designs.
- ¼ wavelength short stub - A coaxial protection design that uses a short stub of specific length to provide surge protection.
- Return loss (VSWR) - The RF matching performance metric used here to show how much signal is reflected by the connector assembly.
- Insertion loss - The loss introduced by the connector path, which matters for signal attenuation in the protected line.
- Insulation resistance - The resistance between relevant terminals, used to confirm electrical isolation after manufacture and after surge stress.
- Impulse durability - The ability of the SPD to withstand a specified number of surge current impulses of specified waveform.
Who uses EN IEC 61169-1-3:2026?
EN IEC 61169-1-3:2026 is used by manufacturers of radio-frequency connectors with built-in SPD, especially coaxial connector assemblies for telecommunications and signalling networks. Test laboratories use it to set up DC sparkover, impulse sparkover and impulse durability testing in a repeatable way.
It is also relevant to design engineers, quality managers and buyers who need to define the required surge protection level, the RF performance limits, and the test fixture to be used. In practice, it supports product specification, incoming verification, type testing and supplier comparison for surge-protected coaxial connectors.

What does the EN IEC 61169-1-3:2026 document contain?
EN IEC 61169-1-3:2026 contains the service conditions, electrical requirements, and test and measurement procedures for built-in SPD in coaxial connectors. It also includes the specification items that the relevant product document must state, so the standard can be applied to a particular connector design.
The figures show example connector types and the test circuits for DC sparkover voltage, impulse sparkover voltage, and impulse durability. Annexes A, B and C provide example equipment, layouts and result views for the three main test families, which helps laboratories build the test setup and understand what to record.

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.

1 Scope
This part of IEC 61169 is applicable to built-in devices (hereinafter referred to as "SPD" – surge
protective device) or surge protection of telecommunications and signalling networks against
indirect and direct effects of lightning or other transient over voltages.
An SPD is intended to protect the electrical apparatus from transient over voltages and to divert
surge currents.
The SPD built in the coaxial connector can be a gas discharge tube type, a ¼ wavelength short
stub type, a flash-off gap type, and a hybrid type thereof.
The purpose of these built-in SPD is to protect modern electronic equipment connected to
telecommunications and signalling networks with nominal system voltages up to 1 000 V (RMS)
AC and 1 500 V DC.
