Hollow metallic waveguides -
Part 2: Relevant specifications 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60153-2 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. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) addition of a cross-sectional view of the waveguide;
b) addition of informative content on the theoretical background of the standard;
c) use of a lower case "k" in the waveguide designation, where appropriate;
IEC 60153-2:2025 © IEC 2025
d) revision of main specification table (now Table 1):
1) two waveguides moved to the end of the table (R 35, R 41);
2) correction of one waveguide designation (now R 26k);
3) correction of one waveguide outside width (R 18);
4) relaxation of tolerances of waveguide outside dimensions (R 14 to R 70);
5) removed attenuation values of waveguides made of gold, aluminium, and stainless steel;
6) implementation of attenuation values for an idealised copper waveguide;
e) relaxation of tolerances of waveguide outside dimensions for R 14 to R 70 in the table now
referred to as Table 4;
f) clarification of the electrical tests:
1) use of standard annealed copper as the reference material for waveguide tubes;
2) correction of the formula for calculating the theoretical attenuation of an idealised copper
waveguide;
3) addition of a formula for calculating the theoretical attenuation of waveguides made of
any material;
4) addition of an informative table with typical waveguide materials (Table 5);
g) addition of an informative cross-reference for waveguide type designations (Annex A).
The text of this International Standard is based on the following documents:

waveguides, can be found on the IEC website at webstore.iec.ch.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be

1 Scope
This part of the IEC 60153 specifies straight hollow metallic tubing of ordinary rectangular
cross-section for use as waveguides in radio frequency electrical applications. The principal
cross-section for such tubing is shown in Figure 1 together with its defining geometrical
dimensions.
NOTE This document serves to define tubular semi-finished products that are characterised by specifying both their
inside and outside dimensions. However, in the case of particularly large and particularly small waveguides, this
document only specifies inside dimensions. This is for production-related reasons.

a outside width r outside corner radius

Figure 1 – Cross-sectional view of ordinary rectangular waveguide tubing
The term "ordinary rectangular waveguide" in the title of this document refers to rectangular
waveguides with a b-to-a ratio of 0,5 (or slightly less).
The objective of this document is to specify for hollow metallic waveguides:
a) the details necessary to ensure compatibility and, as far as is essential, interchangeability;
b) test methods;
c) uniform requirements for the electrical and mechanical properties.
This document does not contain any binding specifications for the materials to be used, but
merely examples. The exact selection of materials is subject to agreement between the
customer and the supplier.

4.1 Overview
IEC 60153-1, which gives general requirements and test methods, shall apply.
4.2 Standardised types
The series of ordinary rectangular waveguides covered in this document is listed in Table 1.
___________
With IEC 60153-2:2016, the series of standardised waveguides was extended to higher frequencies by
introducing eleven additional waveguide sizes. The motivation for this extension was to integrate the sub-
millimetre wavelength waveguides, newly standardised at the time in IEEE Std 1785.1TM-2012, into this
document. The extended series now covers four frequency decades, from 320 MHz to 3,3 THz. In the course of
the extension, a number of other changes also became necessary. They are mentioned informatively in the
corresponding clauses of this document.
