Flanges for waveguides - Part 2: Relevant specifications for flanges for ordinary rectangular waveguides (IEC 60154-2:2016)
IEC 60154-2:2016 specifies the dimensions of flanges for ordinary rectangular waveguide for use in electronic equipment. It covers requirements for flanges drilled before or after mounting on waveguides. It should be noted that for optimum electrical performance, post-drilling of the alignment holes after mounting is recommended. The aim of this standard is to specify for waveguide flanges the mechanical requirements necessary to ensure compatibility and, as far as practicable, interchangeability as well as to ensure adequate electrical performance. 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 R 1200, i.e. R1,2k.

FLANGES FOR WAVEGUIDES –
Part 2: Relevant specifications for flanges
for ordinary rectangular 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.

INTRODUCTION
This International Standard relates to straight hollow metallic tubing for use as waveguides in
electronic equipment. In recent years, the operation frequency of waveguide components and
systems has been extended to 1 THz and above. However, the IEC 60154 series, series of
standards for flanges for waveguides, currently specifies the interface designs up to 40 GHz
for rectangular waveguide. In addition to this, the current issues of the IEC 60154 series of
standards were issued in the 1970’s and do not meet the needs of current applications. This
new edition of IEC 60154-2 addresses these two issues by extending the frequency coverage
to 3 300 GHz and by addressing current applications for this type of waveguide.

FLANGES FOR WAVEGUIDES –
Part 2: Relevant specifications for flanges
for ordinary rectangular waveguides
1 Scope
This part of IEC 60154 specifies the dimensions of flanges for ordinary rectangular waveguide
for use in electronic equipment.
It covers requirements for flanges drilled before or after mounting on waveguides. It should be
noted that for optimum electrical performance, post-drilling of the alignment holes after
mounting is recommended.
The aim of this standard is to specify for waveguide flanges the mechanical requirements
necessary to ensure compatibility and, as far as practicable, interchangeability as well as to
ensure adequate electrical performance.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

comprising the following information:
– 8 – IEC 60154-2:2016 © IEC 2016
a) the number of the present IEC Publication (60154);
b) the letters “IEC";
c) a dash;
d) a letter relating to the basic construction of the flange, flange style, viz:
P = a flange having a gasket groove but no choke groove (formerly called pressurizable).
C = a choke flange with a gasket groove (formerly called choke, pressurizable).
U = a flange having neither a gasket groove nor a choke groove (formerly called
unpressurizable ;
e) a letter for the flange type according to the drawing. Flanges with the same letter and of
the same waveguide size can be mated;
f) the letter and number of the waveguide for which the flange is designed.
Example:

60153 IEC – R 120.
5 Mechanical requirements
5.1 Dimensions
5.1.1 Alignment holes
Holes which are intended as alignment holes are clearly indicated in the drawings and shall
be precision drilled. These alignment holes shall be those which are the nearest to the narrow
side of the waveguide.
Holes which are not intended as alignment holes may be less accurately located than are the
alignment holes, but shall be of correspondingly larger diameter to ensure mating of the
flanges.
5.1.2 Shank diameter of fixing bolts used for alignment
The basic values and deviations thereon are specified in Tables 1 to 5 and Figures 15 to 21.
5.1.3 Relation between shank and alignment hole diameters
For each individual flange, the proper mating of two flanges is ensured by specifying:
a) the location and basic diameters of the holes and the deviations thereon;
b) the basic diameters of the shanks of coupling bolts with the appropriate fit.
For practical reasons, the ISO fits given in Table 1 are recommended:
_____________
AII flat flanges shall have this designation, including those that can be made pressure tight by using gaskets as
indicated in 4.1.

When electrical requirements make it necessary, the hole position tolerance should be
reduced and the hole diameter fit to the shank should be improved accordingly.
Actual values are shown in the respective drawings and tables.
5.1.4 Overall dimensions and thickness of flanges
The values quoted are taken from established designs and it should be noted that these
values are based in general on the use of brass, but for other materials other values might be
more appropriate.
5.1.5 Surface roughness of contact area of flanges
For subsequent study.
5.1.6 Flatness of contact area
The flatness of contact area shall be better than the values given in Table 2:
Table 2 – Requirements of root mean square of roughness on the contact area
Range of sizes Requirement of root mean square of roughness

5.1.7 Perpendicularity of the axis of the holes
The perpendicularity of the axis of the holes to the contact area of the flange shall be
90° ± 1/4°.
5.1.8 General requirements for assemblies
Positioning of the holes shall be based on the theoretical symmetry lines of the inside cross-
section of the waveguide unless otherwise indicated.
5.1.9 Perpendicularity of the contact area
The perpendicularity of the contact area of the flange to the axis of the waveguide shall be
90° ± 1/4°.
– 10 – IEC 60154-2:2016 © IEC 2016
5.2 Additional requirements for unmounted flanges
5.2.1 General
The drawings shown are for mounted flanges. In the individual drawings, one or more
methods are shown by way of example for the mounting of flanges to the waveguide. This,
however, does not exclude socket or through-type methods of mounting if the actual
dimensions allow this. For flanges having a choke groove, the socket type method should be
used.
In the case of flange sizes PDR 3 to PDR 12 inclusive and UDR 3 to UDR 12 inclusive, the
particular cross-section of the flanges to be used is left to the discretion of the individual user.
For the grooved flanges, a rectangular gasket is employed. An example is shown in Figure 14.
The dimensions of the grooves and gaskets for flange sizes PDR 3 to PDR 12 inclusive have
been left for subsequent study.
The flanges are designed for copper alloys, aluminium alloys and magnesium alloys. The
particular type of alloy and finish is to be specified by the user. Unless otherwise specified,
means shall be provided to reduce to a minimum galvanic or other corrosive action. The
particular type of gasket and gasket material is to be specified by the user.
For pre-drilled flanges, the positioning of the holes should be based on the theoretic
symmetry lines of the flange aperture.
5.2.2 Shape of aperture
The requirements for the dimensions of the aperture in the flange only apply to that part which
effects mating between the flange and the waveguide.
The basic dimensions of the flange aperture shown in Table 1 are equal to the basic outside
dimensions of the tubes according to IEC 60153-2.
The deviations for the dimensions of the aperture will depend on the materials and assembly
methods and shall, therefore, be determined by agreement between purchaser and
manufacturer.
For socket types, the front aperture should have dimensions within the deviations specified for
the inside cross-section of the appropriate size of waveguide.
5.2.3 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.
5.3 Information on reflection
The reflections at the flange joint are of three kinds:
a) those caused by the allowed deviations on the internal dimensions of the waveguides;
b) those caused by lateral displacements of the two flange assemblies;
c) those caused by the chokes (in the following, these reflections are not taken into account).
When the deviations on the dimensions of the waveguides (according to IEC 60153-2) and of
the assemblies (according to this standard) sum up to cause maximum lateral displacement
and maximum changes of the waveguide internal dimensions, the theoretical maximum
reflection may be calculated by the ISO/IEC Guide 98-3: 2008 and equation (1):

NOTE 1 The first term within brackets represents the worst case reflection component at a flange joint caused by
changes of the waveguide internal dimensions.
NOTE 2 The second term within brackets represents the reflection component at a flange joint caused by the
displacement of the flange assemblies.
At the high end of the waveguide frequency band, the reflection component is maximum when the displacement
exists in the short wall direction only.
At the low end of the waveguide frequency band, the reflection component is maximum when the displacement
exists in the long wall direction only.
NOTE 3 The maximum reflection at the high end of the waveguide frequency band is smaller than the maximum
reflection at the low end of the band for the small magnitude of displacement.
NOTE 4 The "reflection loss" in decibels is given as a positive quantity.

a
These values are basic values of the outside cross-section of the waveguide according to IEC publication 60153. They should be regarded as basic values for the aperture according to 5.2.2, that apply to
unmounted flanges only.
For through-type flanges, the actual range of deviations for the mounting aperture depends on the assembling method and should therefore be agreed between customer and manufacturer.
For socket flanges, the front-aperture shall have dimensions within the deviations specified for the inside cross-section of the appropriate size of wavegide.
b
These dimensions are given for guidance as being suitable with regard to broadband performance. Actual values should be agreed between customer and manufacturer.
c
These dimensions are not essential for the mating of two assemblies.

FLANGES FOR WAVEGUIDES –
Part 2: Relevant specifications for flanges
for ordinary rectangular 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 60154-2 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,
RF connectors, RF and microwave passive components and accessories
This third edition cancels and replaces the second edition published in 1980. This edition
constitutes a technical revision.

INTRODUCTION
This International Standard relates to straight hollow metallic tubing for use as waveguides in
electronic equipment. In recent years, the operation frequency of waveguide components and
systems has been extended to 1 THz and above. However, the IEC 60154 series, series of
standards for flanges for waveguides, currently specifies the interface designs up to 40 GHz
for rectangular waveguide. In addition to this, the current issues of the IEC 60154 series of
standards were issued in the 1970’s and do not meet the needs of current applications. This
new edition of IEC 60154-2 addresses these two issues by extending the frequency coverage
to 3 300 GHz and by addressing current applications for this type of waveguide.
IEC 60154-2:2016 © IEC 2016 – 7 –
FLANGES FOR WAVEGUIDES –
Part 2: Relevant specifications for flanges
for ordinary rectangular waveguides
1 Scope
This part of IEC 60154 specifies the dimensions of flanges for ordinary rectangular waveguide
for use in electronic equipment.
It covers requirements for flanges drilled before or after mounting on waveguides. It should be
noted that for optimum electrical performance, post-drilling of the alignment holes after
mounting is recommended.
The aim of this standard is to specify for waveguide flanges the mechanical requirements
necessary to ensure compatibility and, as far as practicable, interchangeability as well as to
ensure adequate electrical performance.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

comprising the following information:
– 8 – IEC 60154-2:2016 © IEC 2016
a) the number of the present IEC Publication (60154);
b) the letters “IEC";
c) a dash;
d) a letter relating to the basic construction of the flange, flange style, viz:
P = a flange having a gasket groove but no choke groove (formerly called pressurizable).
C = a choke flange with a gasket groove (formerly called choke, pressurizable).
U = a flange having neither a gasket groove nor a choke groove (formerly called
unpressurizable ;
e) a letter for the flange type according to the drawing. Flanges with the same letter and of
the same waveguide size can be mated;
f) the letter and number of the waveguide for which the flange is designed.
Example:

60153 IEC – R 120.
5 Mechanical requirements
5.1 Dimensions
5.1.1 Alignment holes
Holes which are intended as alignment holes are clearly indicated in the drawings and shall
be precision drilled. These alignment holes shall be those which are the nearest to the narrow
side of the waveguide.
Holes which are not intended as alignment holes may be less accurately located than are the
alignment holes, but shall be of correspondingly larger diameter to ensure mating of the
flanges.
5.1.2 Shank diameter of fixing bolts used for alignment
The basic values and deviations thereon are specified in Tables 1 to 5 and Figures 15 to 21.
5.1.3 Relation between shank and alignment hole diameters
For each individual flange, the proper mating of two flanges is ensured by specifying:
a) the location and basic diameters of the holes and the deviations thereon;
b) the basic diameters of the shanks of coupling bolts with the appropriate fit.
For practical reasons, the ISO fits given in Table 1 are recommended:
_____________
AII flat flanges shall have this designation, including those that can be made pressure tight by using gaskets as
indicated in 4.1.

When electrical requirements make it necessary, the hole position tolerance should be
reduced and the hole diameter fit to the shank should be improved accordingly.
Actual values are shown in the respective drawings and tables.
5.1.4 Overall dimensions and thickness of flanges
The values quoted are taken from established designs and it should be noted that these
values are based in general on the use of brass, but for other materials other values might be
more appropriate.
5.1.5 Surface roughness of contact area of flanges
For subsequent study.
5.1.6 Flatness of contact area
The flatness of contact area shall be better than the values given in Table 2:

5.1.7 Perpendicularity of the axis of the holes
The perpendicularity of the axis of the holes to the contact area of the flange shall be
90° ± 1/4°.
5.1.8 General requirements for assemblies
Positioning of the holes shall be based on the theoretical symmetry lines of the inside cross-
section of the waveguide unless otherwise indicated.
5.1.9 Perpendicularity of the contact area
The perpendicularity of the contact area of the flange to the axis of the waveguide shall be
90° ± 1/4°.
– 10 – IEC 60154-2:2016 © IEC 2016
5.2 Additional requirements for unmounted flanges
5.2.1 General
The drawings shown are for mounted flanges. In the individual drawings, one or more
methods are shown by way of example for the mounting of flanges to the waveguide. This,
however, does not exclude socket or through-type methods of mounting if the actual
dimensions allow this. For flanges having a choke groove, the socket type method should be
used.
In the case of flange sizes PDR 3 to PDR 12 inclusive and UDR 3 to UDR 12 inclusive, the
particular cross-section of the flanges to be used is left to the discretion of the individual user.
For the grooved flanges, a rectangular gasket is employed. An example is shown in Figure 14.
The dimensions of the grooves and gaskets for flange sizes PDR 3 to PDR 12 inclusive have
been left for subsequent study.
The flanges are designed for copper alloys, aluminium alloys and magnesium alloys. The
particular type of alloy and finish is to be specified by the user. Unless otherwise specified,
means shall be provided to reduce to a minimum galvanic or other corrosive action. The
particular type of gasket and gasket material is to be specified by the user.
For pre-drilled flanges, the positioning of the holes should be based on the theoretic
symmetry lines of the flange aperture.
5.2.2 Shape of aperture
The requirements for the dimensions of the aperture in the flange only apply to that part which
effects mating between the flange and the waveguide.
The basic dimensions of the flange aperture shown in Table 1 are equal to the basic outside
dimensions of the tubes according to IEC 60153-2.
The deviations for the dimensions of the aperture will depend on the materials and assembly
methods and shall, therefore, be determined by agreement between purchaser and
manufacturer.
For socket types, the front aperture should have dimensions within the deviations specified for
the inside cross-section of the appropriate size of waveguide.
5.2.3 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.
5.3 Information on reflection
The reflections at the flange joint are of three kinds:
a) those caused by the allowed deviations on the internal dimensions of the waveguides;
b) those caused by lateral displacements of the two flange assemblies;
c) those caused by the chokes (in the following, these reflections are not taken into account).
When the deviations on the dimensions of the waveguides (according to IEC 60153-2) and of
the assemblies (according to this standard) sum up to cause maximum lateral displacement
and maximum changes of the waveguide internal dimensions, the theoretical maximum
reflection may be calculated by the ISO/IEC Guide 98-3: 2008 and equation (1):

NOTE 1 The first term within brackets represents the worst case reflection component at a flange joint caused by
changes of the waveguide internal dimensions.
NOTE 2 The second term within brackets represents the reflection component at a flange joint caused by the
displacement of the flange assemblies.
At the high end of the waveguide frequency band, the reflection component is maximum when the displacement
exists in the short wall direction only.
At the low end of the waveguide frequency band, the reflection component is maximum when the displacement
exists in the long wall direction only.
NOTE 3 The maximum reflection at the high end of the waveguide frequency band is smaller than the maximum
reflection at the low end of the band for the small magnitude of displacement.
NOTE 4 The "reflection loss" in decibels is given as a positive quantity.

These values are basic values of the outside cross-section of the waveguide according to IEC publication 60153. They should be regarded as basic values for the aperture according to 5.2.2, that apply to
unmounted flanges only.
For through-type flanges, the actual range of deviations for the mounting aperture depends on the assembling method and should therefore be agreed between customer and manufacturer.
For socket flanges, the front-aperture shall have dimensions within the deviations specified for the inside cross-section of the appropriate size of wavegide.
b
These dimensions are given for guidance as being suitable with regard to broadband performance. Actual values should be agreed between customer and manufacturer.
c
These dimensions are not essential for the mating of two assemblies.
