27、, IEC Publication 68: Basic Environmental Testing Procedures and shall be used in conjunction with IEC Publication 153: Hollow Metallic Waveguide, and ISO Recommendation R 286. When there is a difference between the general requirements and the relevant specifications, the latter shall prevail. Scop
28、e This standard relates to the dimensions of waveguide flanges for use in electronic equipment. It covers requirements for flanges drilled before or after mounting on waveguides. It should be noted that for optimum electrical performance, post-drilling of the alignment holes after mounting is recomm
29、ended. Object 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 as to ensure adequate electrical performance. 1 General 1.1 Terminology In accordance with IEC Publication 5
30、0(726): International Electrotechnical Vocabulary (I.E.V.), Chapter 726: Transmission Lines and Waveguides. 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 (1
31、54); b) the letters “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); U = a flange having
32、 neither a gasket groove nor a choke groove (formerly called un-pressurizable1). 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 designed. Example: 154 IEC C
33、BR 100 denotes a choke flange of type B for ordinary rectangular waveguide 153 IEC R 100. 1.3 Standard atmospheric conditions for testing 1.3.1 Unless otherwise specified, all tests shall be carried out under standard atmospheric conditions for testing as specified in IEC Publication 68. 1.3.2 Befor
34、e 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. 1.3.3 When measurements are made at a temperature other than the specified temperature, the results shall, where necessary, be correcte
35、d to the specified temperature. The ambient temperature at which the measurements are made shall be stated in the test report. 1.4 Visual inspection Waveguide flanges shall be uniform in composition. There shall be no burrs, cracks, die marks, dirt, grease, scale nor splinters. Contact surfaces shal
36、l have a clean appearance in accordance with good current practice. Compliance is checked by visual inspection. 2 Mechanical requirements 2.1 General requirements both for mounted and unmounted flanges 2.1.1 Holes Holes which are intended as alignment holes shall be precision drilled and clearly ind
37、icated 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 to ensure mating of the flanges (see Sub-clause 2.1.3). 1) All flat flanges shall have this desi
38、gnation, including those that can be made pressure tight by using gaskets.

39、 standardized: The deviation on the basic shank diameter shall be according to ISO fit h8. 2.1.3 Relation between shank and alignment hole diameters For each individual flange, the proper mating of two flanges is ensured by specifying: a) the location and the basic diameters of the holes and the dev
40、iations thereon; b) the basic diameters of the shanks of coupling bolts with the appropriate fit. The basic diameter of the holes shall be the same as that of the corresponding bolt shank. The deviation on the hole diameter shall be specified for an ISO grade 9 fit for the alignment holes and for th
41、e corresponding ISO grade 15 fit for the attachment holes. The positional tolerance on the holes shall be specified using either the rectilinear or the circular tolerancing method. Depending upon which method is used, the clearance between the maximum shank diameter (dmax) and the minimum hole diame
42、ter (Dmin) shall conform to one of the following (the inequality sign prevents the possibility of an interference fit): Rectilinear tolerances where: d = the hole position tolerance in both directions. NOTEThe multiplication factor of takes into account the displacement in two directions perpendicul
43、ar to each other. Circular tolerances Dmin dmax Z where: Z = the diameter of the circular tolerance zone. 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
44、other materials other values might be more appropriate. 2.1.5 Surface roughness of contact area of contact flanges For subsequent study. 2.1.6 Flatness of contact area The requirements on the flatness of the contact area shall be specified in the relevant specification. 2.1.7 Perpendicularity of the
45、 axis of the holes The perpendicularity of the axis of the holes to the contact area of the flange shall be 90 . NOTEWhen the circular tolerancing method is applied to the position of the holes, a perpendicularity requirement is implied. 2.2 General requirements for mounted flanges (assemblies) 2.2.
46、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. 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 . 2.3 Addition
47、al 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 for the mounting of flanges to the waveguide by way of example. This, however, does not exclude other methods of mounting. 2.3.2 Shape of aperture
48、The requirements for the dimensions of the aperture in the flange only apply to that part which affects mating between the flange and the waveguide. The basic dimensions of the flange aperture shown in the tables are equal to the basic outside dimensions of the tubes according to the IEC Publication
49、 153 series. The deviation on the dimensions of the aperture will depend on the materials and the assembly methods and shall therefore be agreed upon between purchaser and manufacturer. mmin 8.00.315a 6.350.250 5.00.197 4.170.164 4.00.158 3.00.118 a This value has been standardized for flanges originally designed to take bolts with 0.3125 in basic shank diameter. However, clearance and positional tolerance for the general purpose flanges are so chosen that bolts with 0.3125 in (7.94 mm) as well as 8.0 mm (0.315 in) sha
