INTERNATIONAL ELECTROTECHNICAL COMMISSION
FLANGES FOR WAVEGUIDES
Part 4: Relevant specifications for flanges
for circular waveguides
FOREWORD
1)The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) In order to promote this inte rnational unification, the IEC expresses the wish that all National Committees having as
yet no national rules, when preparing such rules, should use the IEC recommendations as the fundamental basis for these
rules in so far as national conditions will permit.
4) The desirability is recognized of extending inte rn
ational agreement on these matters through an endeavour to harmonize
national standardization rules with these recommendations in so far as national conditions will permit. The National
Committees pledge their influence towards that end.
5) The I E C has not laid down any procedure concerning marking as an indication of approval and has no responsibility
when an item of equipment is declared to comply with one of its recommendations.
PREFACE
This Recommendation has been prepared by Sub-Committee 46B, Waveguides and their Accessories,
of IEC Technical Committee No. 46, Cables, Wires and Waveguides for Telecommunication Equipment.
It forms the fourth pa of the complete Recommendation dealing with Flanges for Waveguides, and
rt
should be used in conjunction with Part 1, General Requirements and Measuring Methods, issued as
IEC Publication 154-1.
Subsequent relevant specifications for other types of flanges will be issued in separate publications.
A draft was discussed at the meeting held in Bucharest in 1962, as a result of which a new draft was
submitted to the National Committees for approval under the Six Months' Rule in January 1964. Comments
received were discussed at the meetings held in Baden-Baden in 1965 and in Tel-Aviv in 1966. Amend-
ments were submitted to the National Committees for approval under the Two Months' Procedure in
April 1967.
The following countries voted explicitly in favour of publication of Part 4:
Korea (Republic of)
Australia
Belgium South Africa
Czechoslovakia Sweden
Denmark Switzerland
Turkey
Finland
United Kingdom
France
United States of America
Germany
Yugoslavia
Israel
Italy Netherlands
Japan

DIMENSIONAL DEVIATIONS
The values for the permissible deviations in this Recommendation follow the principles given in ISO
Recommendation R 286, ISO System of Limits and Fits, where:
Deviation is defined as:
Algebraical difference between a size (actual maximum, etc.) and the corresponding basic size.
Upper deviation is defined as:
Algebraical difference between the maximum limits of size and the corresponding basic size.
And lower deviation is defined as:
Algebraical difference between the minimum limit of size and the corresponding basic size.
It should be noted that the upper and lower deviations may have like signs, unlike signs or either
deviation may be zero. This permits the basic sizes of mating shafts and holes to be identical.
The older concept of plus tolerances and minus tolerances has an undesirable limitation, in that the
basic sizes of mating shafts and holes cannot be identical for clearance fits.

154-1
1. General
Standardized types
The series of flanges for circular waveguides covered by this Recommendation is
shown in Figures 1 to 4 and in Tables Ia and Ib. Flanges for preferred waveguide
sizes are shown in Table Ia. Flanges for both the intermediate and preferred wave-
guide sizes are shown in Table Ib.
1.2 Type designation
For these flanges, the type designation comprises:
a) The code: 154 IEC
b) A dash
c) A letter relating to the basic construction of the flange, viz.:
P =
pressurizable
U = unpressurizable
d) A letter for the type according to the drawing
e) The letter and number of the waveguide for which the flange is designed.
Example: 154 IEC — PJC 18 denotes a pressurizable type flange for circular
waveguide 153 IEC — C 18.
2. Mechanical requirements
2.1
General requirements both for assemblies and for unmounted flanges
It should be noted that no recommendations are made for the materials to be used
for flanges for waveguides. The choice of material must be agreed on between customer
and manufacturer.
The cross-section of the circlip shown in the drawings is given for information only.
The actual cross-section may assume any shape that does not adversely affect the
mating of the flanges.
2.1.1 Locating holes
Not applicable, because location is not effected by bolts and holes.
2.1.2 Shank diameter of fixing bolts used for location
Not applicable, because location is not effected by bolts and holes.
2.1.3
Relation between shank and locating hole diameters
Not applicable, because location is not effected by bolts and holes.

area of the flange to the axis of the waveguide shall be 90+ %4°
2.3 Additional requirements for unmounted flanges
General
2.3.1
The drawings shown 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.
2.3.2 Shape of aperture
Shall conform to the requirements specified in Part 1 of the Recommendation.
2.3.3 Positioning of the holes
Positioning of the holes shall be as shown in the figures and in the tables.
2.3.4 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.

APPENDIX A
NOTES FOR TABLE la (METRIC AND INCH)
1.
These values are the basic (nominal) values of the outside cross-section of the waveguide according to
IEC Publication 153, Hollow Metallic Waveguides, and should be regarded as nominal values for the
aperture according to IEC Publication 154-1, Sub-clause 2.3.2, and they apply to unmounted flanges
only.
When the outside diameters D
1 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.
2.
The outer diameters D 1 for waveguide sizes C 30 to C 89 were increased some time after the major
dimensions in this standard 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. Alter-
natively, a socket type flange could be used.
3. 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 pa
rts. 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 154 IEC — PJC 18
The maximum shaft diameter is 133.00 mm (5.2362 in)
The minimum shaft diameter is 132.960 mm (5.2346 in)
The maximum hole diameter is 133.083 mm (5.2394 in)
The minimum hole diameter is 133.043 mm (5.2378 in).
4. The actual position of any hole shall be within a tolerance zone diameter 0 of 0.4 mm (0.016 in),
concentric to the theoretical position of the hole.
5. The symbol () indicates the maximum eccentricity of the flange dimension C with respect to the
waveguide inside cross-section dimension D. (Sec IEC Publication 153-4, Hollow Metallic Waveguide,
Part 4: Relevant Specifications for Circular Waveguides.)
6.
These figures, which are given for information only, are calculated maximum values of the axial o ffset
resulting from the most unfavourable combinations of deviations and eccentricities.

APPENDIX B
NOTES FOR TABLE Ib (METRIC AND INCH)
1. 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.
2. These values are the basic (nominal) values of the outside cross-section of the waveguide according to
IEC Publication 153 and should be regarded as nominal values for the aperture according to IEC Publi-
cation 154-1, Sub-clause 2.3.2, and they apply to unmounted flanges only.
When the outside diameters D for preferred waveguide sizes C 18, C 22, C 25 and the intermediate
1
sizes in this table are standardized, it may be necessary to modify certain dimensions of these flanges
to ensure compatibility with the waveguide.
3. The outer diameters D for waveguide sizes C 30 to C 89 were increased some time after the major
1
dimensions in the standard 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. Alter-
natively, 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
4.
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 154 IEC — PJC 18
The maximum shaft diameter is 133.00 mm (5.2362 in)
The minimum shaft diameter is 132.960 mm (5.2346 in)
The maximum hole diameter is 133.083 mm (5.2394 in)
The minimum hole diameter is 133.043 mm (5.2378 in).
5. The actual position of any hole shall be within a tolerance zone diameter 0 of 0.4 mm (or 0.016 in),
concentric to the theoretical position of the hole.
The symbol U indicates the maximum eccentricity of the flange dimension C with respect to the
6.
waveguide inside cross-section dimension D in IEC Publication 153-4.
7. 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.
