22、echnical 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 Specificati
23、ons, 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,
24、 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 decis
25、ions 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 intern
26、ational 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 ord
27、er 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 cle
28、arly 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
29、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, prop
30、erty 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
31、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
32、 or all such patent rights. International Standard IEC 60154-1 has been prepared by subcommittee 46F: RF and microwave passive components, of IEC technical committee 46: Cables, wires, waveguides, RF connectors, RF and microwave passive components and accessories. This third edition cancels and repl
33、aces the second edition published in 1982. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) define the alignment pin and hole for waveguide alignment; b) specify the dimensions in the metric syst
34、em.

37、N This International Standard relates to straight hollow metallic tubing for use as waveguides in electronic equipment. In recent years, the operation frequency of waveguide components and systems has been extended to 1 THz and above. However, the IEC 60154 series of standards for flanges for wavegu
38、ides, currently specifies the interface design up to 40 GHz for rectangular waveguides. In addition to this, the current issues of the IEC 60154 series of standards were issued in the 1970s and do not meet the needs of current applications. This new edition of IEC 60154-1 addresses these two issues.
39、 BS EN 60154-1:2016 6 IEC 60154-1:2016 IEC 2016 FLANGES FOR WAVEGUIDES Part 1: General requirements 1 Scope This part of IEC 60154 specifies the dimensions of waveguide flanges for use in electronic equipment. It covers requirements for flanges drilled before or after mounting on waveguides. It shou
40、ld be noted that for optimum electrical performance, post-drilling of the alignment holes after mounting is recommended. The aim of this standard is to specify for waveguide flanges the mechanical requirements necessary to ensure compatibility and, as far as practicable, interchangeability as well a
41、s to ensure adequate electrical performance. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of
42、 the referenced document (including any amendments) applies. IEC 60050 (all parts), International Electrotechnical Vocabulary (available at http:/www.electropedia.org/) IEC 60068 (all parts), Environmental testing IEC 60153 (all parts), Hollow metallic waveguides 3 Terms and definitions For the purp
43、oses of this document, the terms and definitions given in IEC 60050-726 apply. 4 General 4.1 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 (60154); b) the lette
44、rs “IEC“; c) a dash; d) a letter relating to the basic construction of the flange style, i.e.: 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); BS EN 60154-1:2016IEC 60154-1:2016 I
45、EC 2016 7 U = a flange having neither a gasket groove nor a choke groove (formerly called unpressurizable1); e) a letter for the 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
46、designed. Example: “60154 IEC-CBR 100“ denotes a choke flange of type B for ordinary rectangular waveguide 60153 IEC-R 100. 4.2 Standard atmospheric conditions for testing Unless otherwise specified, all tests shall be carried out under standard atmospheric conditions for testing as specified in IEC
47、 60068. Before the measurements are made, the flanges shall be stored at the measuring temperature for a time sufficient to allow the entire waveguide to reach this temperature. When measurements are made at a temperature other than the specified temperature, the results shall, where necessary, be c
48、orrected to the specified temperature. The ambient temperature at which the measurements are made shall be stated in the test report. 4.3 Visual inspection Waveguide flanges shall be uniform in composition. There shall be no burrs, cracks, die marks, dirt, grease, scale nor splinters. Contact surfac
49、es shall have a clean appearance in accordance with good current practice. Compliance is checked by visual inspection. 5 Mechanical requirements 5.1 General requirements both for mounted and unmounted flanges 5.1.1 Holes Holes which are intended as alignment holes shall be precision drilled and clearly indicated on the drawing. Holes which are not intended for alignment, i.e. attachment holes, may be less accurately located than are the alignment holes, but shall then be of correspondingly larger diameter t
