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.

of the waveguide shall be 90° ± 1/4°.
5.3 Additional requirements for unmounted flanges
5.3.1 General

Figures B.1 to B.4 are for mounted flanges. In the individual drawings, the through type

mounting of flanges to the waveguide is shown by way of example. This, however, does not

exclude another method of mounting if the actual dimensions allow this.

It should be noted that for optimum electrical performance, post-drilling of the alignment holes

after mounting is recommended.
5.3.2 Shape of aperture

The shape of aperture shall conform to the requirements specified in IEC 60154-1.

5.3.3 Positioning of the holes

Positioning of the holes shall be as shown in Figures B.1 to B.4 and in Tables 1, A.1 and B.1.

5.3.4 Ordering information

When ordering unmounted flanges, an allowance should be made on certain of the specified

dimensions to cover the effects of possible machining after mounting.
---------------------- Page: 9 ----------------------
– 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.
