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
This standard has been prepared by Sub-Committee 46B, Waveguides and Their Accessories, of IEC Technical Committee
No. 46, Cables, Wires and Waveguides for Telecommunication Equipment, and replaces the first edition of 1968, as well as its
amendment, Publication 154-2, Amendment No. 1 (1969).
A draft on rim dimensions for PDR 14 to PDR 180 flanges was discussed at the meeting held in Bucharest in 1974 and as
a result of this meeting, Document 46B(Central Office)65 was submitted to the National Committees for approval under the
Six Months' Rule in March 1975.
The following countries voted explicitly in favour of publication:
Italy Belgium Switzerland
Denmark Poland Turkey
France Romania United Kingdom
German y Spain United States of America

A draft on ali gnment hole location and circular tolerancin g dimensions for E T\pe flan ges was discussed at the meetin g held in
Bucharest in 1974 and as a result of this meeting, Document 46B(Central 011ice)67 was submitted to the National Committees
for approval under the Six Months' Rule in July 1975.
The following countries voted explicitly in favour of publication:

A draft on the tolerances of flan ges in the range PDR 14 to PDR 180 and UDR 120 to UDR ISO by inscribin g a circular
tolerance zone within the existing alignment holes' square tolerance zone was discussed at the meeting held in Bucharest in 1974
and as a result of this meeting, Document 46B(Central Office)70 was submitted to the National Committees for approval under
the Six Months' Role in July 1976.
The following countries voted explicitly in favour of publication:

A draft on deletion of flange Types F and H was discussed at the meeting held in Bucharest in 1974 and as a result of this
meeting, Document 46B(Central Office)73 was submitted to the National Committees for approval under the Six Months' Rule
in May 1976.
The following countries voted explicitly in favour of publication:

A draft on attachment hole location and the circular tolerancing dimensions for E Type flanges was discussed at the meeting
held in Stockholm in 1976, and as a result of that meeting, Document 46B(Secretariat)84 was circulated to the National Com-
mittees under the Accelerated Procedure. In July 1978, Document 46B(Central Office)79 was submitted to the National Committees,
for approval under the Six Months' Rule.
The following countries voted explicitly in favour of publication:
Belgium Switzerland
Japan
Egypt Poland Turkey
Germany Spain United Kingdom
Italy Sweden United States of America
Subsequent to the meeting held in Stockholm in 1976 a draft on deviations of attachment hole diameters for D Type flanges,
Document 46B(Secretariat)85, was circulated to the National Committees under the Accelerated Procedure. In July 1978,
Document 46B(Central Office)83 was submitted to the National Committees for approval under the Six Months' Rule.
The following countries voted explicitly in favour of publication:
Australia Germany Sweden
Belgium Italy Switzerland
Canada Netherlands Turkey
France Poland United Kingdom
At the 1978 Florence meeting an earlier decision was reconfirmed to standardize UDR flanges where there are PDR counter-
parts. In September 1978, Document 46B(Central Office)84 was submitted to the National Committees for approval under the
Two Months' Procedure.
The following countries voted explicitly in favour of publication:

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:

where:

Noms 1. — The first terni within brackets represents the worst case reflection component at a flan g
e joint caused by changes
of the wave guide internal dimensions.
'. — The second term within brackets represents the reflection component at a flange joint caused by the displacement
of the flan
ge assemblies.
At the hi gh 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 lon g wall direction only.
The maximum reflection at the high end of the wave
3. guide frequency band is smaller than the maximum reflection
at the low end of the band for the same magnitude of displacement.
4. — The "reflection loss" in decibels is given as a positive quantity.
