Passive RF and microwave devices, intermodulation level measurement - Part 3: Measurement of passive intermodulation in coaxial connectors (IEC 62037-3:2021)
This part of IEC 62037 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector, as independently as possible from the effects of cable PIM (passive intermodulation).
For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission-line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts is applied to the connectors while measuring the PIM.

L'IEC 62037-3:2021 définit l’essai de choc sur des connecteurs coaxiaux pour évaluer leur robustesse dans le cas de connexions faibles et de particules à l’intérieur des connecteurs, aussi indépendamment que possible des effets de l’intermodulation passive des câbles. Pour les autres connecteurs (par exemple les connecteurs montés sur panneaux), le câble peut être remplacé par une ligne de transmission adéquate (par exemple une ligne à air, une ligne à ruban). Afin d’évaluer les effets des contraintes mécaniques sur les connecteurs, une série de chocs est appliquée aux connecteurs, tout en mesurant l’intermodulation passive. Cette seconde édition annule et remplace la première édition parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a. modification de la méthode d’impact pour utiliser une bille en acier plutôt qu’une tige en laiton;
b. ajout de l’énergie de choc exigée pour soumettre à l’essai chaque type de connecteur;
c. ajout de la méthode pour calculer l’énergie de choc pour les types de connecteurs non répertoriés dans le document.

Ta del standarda IEC 62037 določa preskus vpliva na koaksialne konektorje za ugotavljanje njihove trdnosti v primerjavi s šibkimi povezavami in delci v konektorju, čim bolj neodvisno od učinkov kabla PIM (pasivna intermodulacija). Pri drugih konektorjih (npr. konektorji za panelno vgradnjo) je kabel mogoče nadomestiti z ustreznim prenosnim daljnovodom (npr. zračni vod, ploščati valovod). Za ocenjevanje učinkov mehanskih vplivov na konektorje se med merjenjem pasivne intermodulacije uporablja skupina vplivov.
General Information

Overview
EN IEC 62037-3:2021 (endorsed by CLC/CENELEC) is the IEC standard that specifies impact-test methods for measuring passive intermodulation (PIM) in coaxial connectors. The standard is part of the IEC 62037 series on intermodulation level measurement and focuses on assessing connector robustness to weak electrical contacts and contaminants while minimising the influence of cable PIM.
This part defines test set-ups, connection and measurement considerations, and the impact procedure (using a steel ball) to evaluate mechanical stress effects on PIM.
Key Topics
- Purpose and scope: Evaluate passive intermodulation in coaxial connectors independently of cable PIM to assess vulnerability to loose connections and particles.
- Test set-ups:
- Set-up 1 - Multi-port DUT: Short assemblies with identical connectors at each end; minimise transmission-line effects.
- Set-up 2 - One-port DUT: Single connector on a transmission line that provides at least 10 dB attenuation in one direction at the lowest receive-band frequency.
- Frequency considerations: For fixed-frequency tests, determine the frequency with maximum PIM within the test band. Assemblies of varying electrical lengths (including λ/6 and λ/3 longer variants) may be used to ensure PIM adds in-phase and to identify worst-case response.
- Impact method: A steel ball is used as the drop mass to avoid sharp edges; a minimum of five impacts are applied to the device under test. Annex A and B provide methods to calculate equivalent impact energy and to adapt impact energy for different connector types.
- Reporting and references: Results and test conditions are reported per the standard. Normative links include IEC 62037-1 (general requirements) and IEC 62037-4 (coaxial cable PIM verification).
Applications
- RF connector qualification and incoming quality control for manufacturers of coaxial connectors and assemblies.
- Laboratory PIM testing during product development to identify mechanical vulnerabilities that produce passive intermodulation.
- Field assurance and acceptance testing for base station hardware, antenna feed systems, and other RF installations where low PIM is critical.
- Comparative evaluation of connector designs and materials to reduce site failures caused by weak contacts or particulate contamination.
Related Standards
- IEC 62037-1 - General requirements and measuring methods for PIM (referenced normative document).
- IEC 62037-4 - Measurement of passive intermodulation in coaxial cables (used to verify cable PIM performance prior to connector testing).
Practical value: EN IEC 62037-3:2021 provides a repeatable impact-test framework that helps engineers and test labs isolate connector-origin PIM, standardise test procedures, and support robust RF connector qualification and field reliability assessments.

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
...
