FLANGES FOR WAVEGUIDES –
Part 4: Relevant specifications for flanges for circular waveguides

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.
International Standard IEC 60154-4 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee TC 46: Cables, wires,
waveguides, RF connectors, RF and microwave passive components and accessories.
This second edition cancels and replaces the first edition published in 1969. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revise the estimation for return loss at connection interface of waveguides;
b) add two type of waveguide flange for high frequency application, i.e. over 50 GHz;
c) expand the operation frequency range up to 3,3 THz;
d) rename the frequency band over R1200, i.e. R1.2K.

– 8 – IEC 60154-4:2017 © IEC 2017
Annex A
(normative)
Dimensions of flanges for preferred waveguide sizes
The values given in Table A.1 are the basic (nominal) values of the outside cross-section of
the waveguide according to IEC 60153 (all parts), and should be regarded as nominal values
for the aperture according to IEC 60154-1:2016, 5.2.2, and they apply to unmounted flanges
only.
When the outside D1 of circular waveguide sizes C 18, C 22, and C 25 are standardized, it
may be necessary to modify some dimensions of these flanges to ensure compatibility with
the waveguide.
The outer diameters D1 for waveguide sizes C 30 to C 89 were increased some time after the
major dimensions in this document were approved and the gasket grooves may, in some
cases, cut into the waveguide wall. It will be necessary in such cases to machine the gasket
groove after assembly. Alternatively, a socket type flange could be used.
Each flange is comprised of a castellated ring and a part which is fixed to the waveguide. For
this series of flanges, location depends on the fit between each castellated ring and both fixed
parts. The diameter of the fixed part is called “shaft” in the table and the diameter of the
castellated ring aperture is called “hole”. The fit between these dimensions is ISO F7/h7 for
sizes C 18 up to C 140.
Example: Flange 60154 IEC – PJC 18
• The maximum shaft diameter is 133,00 mm.
• The minimum shaft diameter is 132,960 mm.
• The maximum hole diameter is 133,083 mm.
• The minimum hole diameter is 133,043 mm.
The actual position of any hole shall be within a tolerance zone diameter φ of 0,4 mm,
concentric to the theoretical position of the hole.
The symbol ◎ indicates the maximum eccentricity of the flange dimension C with respect to
the waveguides inside cross-section dimension D (see IEC 60153-4).
The figures given in Table A.1, which are given for information only, are calculated maximum
values of the axial offset resulting from the most unfavourable combinations of deviations and
eccentricities.

Annex B
(normative)
Dimensions of flanges for both intermediate
and preferred waveguide sizes
The designations given for the preferred sizes were rounded off before the intermediate sizes
were given their designations. This accounts for the small step which occasionally occurs
between a preferred size designation and an adjacent intermediate size designation.
These values are the basic (nominal) values of the outside cross-section of the waveguide
according to IEC 60153 (all parts) and should be regarded as nominal values for the aperture
according to IEC 60154-1:2016, 5.2.2, and they apply to un mounted flanges only.
When the outside diameters D1 for preferred waveguide sizes C 18, C 22, C 25 and the
intermediate sizes in Table B.1 are standardized, it may be necessary to modify certain
dimensions of these flanges to ensure compatibility with the waveguide.
The outer diameters D1 for waveguide sizes C 30 to C 89 were increased some time after the
major dimensions in this document were approved and the gasket grooves may, in some
cases, cut into the waveguide wall. It will be necessary in such cases to machine the gasket
groove after assembly. Alternatively, a socket type flange could be used.
Each flange is comprised of a castellated ring and a part which ids fixed to the waveguide.
For this series of flanges, location depends on the fit between each castellated ring and both
fixed parts. The diameter of the fixed part is called “shaft” in the table and the diameter of the
castellated ring aperture is called “hole”. The fit between these dimensions is ISO f7/h7 for
sizes C 18 up to C 140.
Example: Flange 60154 IEC – PJC 18
• The maximum shaft diameter is 133,00 mm.
• The minimum shaft diameter is 132,960 mm.
• The maximum hole diameter is 133,083 mm.
• The minimum hole diameter is 133,043 mm.
The actual position of any hole shall be within a tolerance zone diameter φ of 0,4 mm (or
0,016 in), concentric to the theoretical position of the hole.
The symbol ◎ indicates the maximum eccentricity of the flange dimension C with respect to
the waveguide inside cross-section dimension D in IEC 60153-4.
These figures, which are given for information only, are calculated maximum values of the
axial offset resulting from the most unfavourable combinations of deviations and eccentricities.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ce
...
