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.
In order to promote international unification, the I EC expresses the wish that all National Committees should adopt the text of
3)
the I EC recommendation for their national rules in so far as national conditions will permit. Any divergence between the
IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.
4) The IEC 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

DIMENSIONAL DEVIATIONS
The values for the permissible deviations in this standard follow the principles given in ISO Recommendation R286,
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 limit 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.

FLANGES FOR WAVEGUIDES
Part 2: Relevant specifications for flanges for ordinary rectangular waveguides
FLANGES FOR ORDINARY RECTANGULAR WAVEGUIDES
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 Publication 153-2,
Hollow Metallic Waveguides, Part 2: Relevant Specifications for Ordinary Rectangular Waveguides)
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 from:

1. General
1.1 Standardized types
The series of flanges for ordinary rectangular waveguides covered by this standard
are shown in Tables Ito V and Figures 12 C to 12 I.
Flat flanges can be used with metal plate air seal gaskets or shims (an example
is shown in Figure 12 A).
1.2 Flange designation
Waveguide flanges covered by this standard shall be indicated by a reference
number comprising the following information:
a)
The number of the present IEC Publication (154).
b) The letters "1 E C".
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:
154 IEC — UDR 120 denotes a flange without a gasket groove of
Type D, for use with rectangular waveguide 153 IEC— R 120.
* All flat flanges shall have this desi gnation, including those that can be made pressure tight by
using gaskets as indicated in Sub-clause 1.1.
2. Mechanical requirements
2.1
Dimensions
2.1.1 Alignment holes
Holes which are intended as alignment holes are clearl
y indicated in the drawings
and shall be precision drilled. These ali g
nment 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 must be of correspondingly larger diameter to
ensure mating of the flanges.
2.1.2
Shank diameter of fixing bolts used for alignment '
The basic values and deviations thereon are specified in Tables I to V and
Figures 12 C to 12 I.

Item
Clause No.
2.1.3 Relation between shank and alignment hole diameters
For each individual flange, the proper matinmatin g 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 following ISO fits are recommended :

Circular flanges for type R

Note. — When electrical requirements make it necessary, the hole position tolerance may be reduced and
the hole diameter fit to the shank should be improved accordingly.
Actual values are shown in the respective drawin gs and tables.
2.1.4 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.
2.1.5 Surface roughness of contact area of flat flanges
For subsequent study.
2.1.6 Flatness ofcontact area
The flatness of contact area shall be better than the values given in the following
table:

The perpendicularity of the axis of the holes to the contact area of the flange shall
be 90 + 1/4'.

Clause No. Item
2.2
General requirements for assemblies
2.2.1 Positioning of the holes
Positioning of the holes shall be based on the theoretical symmetry lines of the inside
cross-section of the waveguide unless otherwise indicated.
2.2.2 Perpendicularity of the contact area
The perpendicularity of the contact area of the flange to the axis of the waveguide
shall be 90 +'/4°.
2.3 Additional requirements for unmounted flanges
2.3.1 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 12 B. 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.
Note. — For pre-drilled flanges the positioning of the holes should be based on the theoretical symmetry
lines of the flange aperature.
2.3.2 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 I are equal to the basic
outside dimensions of the tubes accordin g to IEC Publication 153-2.
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.
Note. —
For socket-types, the front aperture shall have dimensions within the deviations specified for
the inside cross-section of the appropriate size of waveguide.
2.3.3 Ordering information
When ordering unmounted flan ges, an allowance should be made on certain of the
specified dimensions to cover the effects of possible machining after mounting.
