HOLLOW METALLIC WAVEGUIDES –
Part 4: Relevant specifications 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 60153-4 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 third edition cancels and replaces the second edition published in 1973-1. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Expand and revise the operation frequency range for waveguides;
b) Revise the allowance of aperture dimensions;
c) Revise the test method for aperture dimensions;
d) Revise the equation of attenuation.

5.2.2 Basic diameter deviations
The values of inner diameter deviations specified in Table 1 are based on the general
principle as given in Table 3.
Table 3 – Inner Diameter deviations
Range of sizes Deviation ±
mm
C 3.3 to C 165 1/1 000 of inside basic diameter
C 190 to C 890 0,010
C 255 to C 29000 0,0078
5.2.3 Ellipticity
The ellipticity “E” is defined as
𝐷𝐷 −𝐷𝐷
𝑚𝑚𝑚𝑚𝑚𝑚 𝑚𝑚𝑚𝑚𝑚𝑚
E=
𝐷𝐷
𝑚𝑚𝑛𝑛𝑚𝑚
Where
𝐷𝐷 = the basic inside diameter
𝑚𝑚𝑛𝑛𝑚𝑚
𝐷𝐷 = the largest measured inside dimension
𝑚𝑚𝑚𝑚𝑚𝑚
𝐷𝐷 = the smallest measured inside dimension
𝑚𝑚𝑚𝑚𝑚𝑚
The ellipticity E shall not exceed 0,001 at any cross-section for types C 3.3 to C 165 inclusive.
For sizes C 190 and smaller dimensions: the requirement for ellipticity is for further study.
5.2.4 Wall thickness
The basic values specified in Table 1 conform to the following rules.
The basic wall thickness is defined as half the difference between the basic outside and
inside dimensions in the original systems of units.
After conversion from inches into mm, the values were rounded to the nearest 0,005 mm.
After conversion from mm into inches, the values were rounded to the nearest 0,001 in.
5.2.5 Eccentricity
The eccentricity is defined as half the difference between the measured thickness of opposite
walls. Unless otherwise specified, the eccentricity shall not exceed 10 % of the basic wall
thickness. For the determination of the eccentricity, the thicknesses shall be measured where
they give the most unfavourable result.
5.2.6 Outside dimensions
The basic values and the deviations are specified in Table 1.
No outside dimensions have been specified for some of the largest sizes because a variety of
manufacturing techniques are used.
The values of the outside diameter deviations specified in Table 1 are based on Table 4.

C 89 – C 120 0.065
C 140 – C 165 0.055
C 190 – C890 0.051
C1040 – C29000 If necessary, outside dimension should be specified.
NOTE Deviations for the sizes C 18 to C 165 inclusive correspond to ISO limit is If.
5.3 Other mechanical requirements
5.3.1 Bow
Bow is defined as the maximum departure of the actual axis of the waveguide from a straight
line of specified length connecting two points on that axis.
The vow is measured on the external surface of the waveguide. For a length of 10 times the
internal width, the external bow shall not exceed 10 times the specified deviation on the
internal width.
For a length of 50 times the internal width, the external bow shall not exceed 40 times the
specified deviation on the internal width.
For the determination of the external bow, the waveguide shall be so positioned that gravity
does not tend to affect the amount of bow.
5.3.2 Surface roughness
Under consideration.
5.3.3 Internal stresses
The waveguide tube shall be cut by means of a saw. The cutting process must be carefully
controlled so as to avoid distortion arising from the cutting, and the use of a fine high-speed
saw is recommended. After cutting, the cross-section of the waveguide tube shall still be
within the specified deviations.
6 Electrical tests – Attenuation
The maximum attenuation in the TE mode for waveguide IEC – C 104 and waveguides with
larger dimensions shall not exceed 1,3 times the value calculated from the formula below at a
frequency of 1,2 times the cut-off frequency in the same mode. The values given in the table
are for waveguides made of copper with standard conductivity σ = 5.80 × 10 Siemens /
metre.
