28、 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,
29、 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 preparator
30、y 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 organizatio
31、ns. 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 rec
32、ommendations 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
33、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 p
34、ublication 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 ind
35、ependent 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 an
36、y 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 Normati
37、ve 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 responsi
38、ble for identifying any or all such patent rights. International Standard IEC 60154-4 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 seco
39、nd edition cancels and replaces the first edition published in 1969. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revise the estimation for return loss at connection interface of waveguides;
40、b) add two type of waveguide flange for high frequency application, i.e. over 50 GHz; c) expand the operation frequency range up to 3,3 THz; d) rename the frequency band over R1200, i.e. R1.2K. 4 IEC 60154-4:2017 IEC 2017 The text of this document is based on the following documents: CDV Report on v
41、oting 46F/346A/CDV 46F/358/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60154 seri
42、es, published under the general title Flanges for waveguides, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific do
43、cument. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

44、rs should therefore print this document using a colour printer. IEC 60154-4:2017 IEC 2017 5 FLANGES FOR WAVEGUIDES Part 4: Relevant specifications for flanges for circular waveguides 1 Scope This part of IEC 60154-4 specifies the dimensions of flanges for circular waveguides for use in electronic eq
45、uipment. It covers requirements for flanges drilled before or after mounting on waveguides. The aim of this document is to specify for waveguide flanges the mechanical requirements necessary to ensure compatibility and, as far as practicable, interchangeability as well as to ensure adequate electric
46、al performance. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc
47、ument (including any amendments) applies. IEC 60154-1:2016, Flanges for waveguides General requirements 3 Terms and definitions No terms and definitions are listed in this document.
