Annotation of standard text IEC 60153-4-ed.4.0 :
IEC 60153-4:2022 specifies straight hollow metallic tubing of circular cross section for use as waveguides in electronic equipment. The aim of this document is to specify the hollow metallic waveguides: a) the details necessary to ensure compatibility and, as far as essential, interchangeability; b) test methods; c) uniform requirements for the electrical and mechanical properties This document is intended to be read in conjunction with IEC 60153-1, which gives general requirements and test methods. This fourth edition cancels and replaces the third edition published in 2017. edition: a. change of the designation scheme for small circular waveguides (e.g. C 25.5k instead of C 25500); b. revision of Table 1: - correction of two waveguide designations (now C 1.2k, C 12k); - correction of three waveguide diameters (C 140, C 1.4k, C 14k); - tightening of inner diameter tolerances for waveguides smaller than C 890; - deletion of waveguide attenuation values for aluminium, gold, and brass; c. deletion of Table 2 (duplication) and replacement with the table of intermediate waveguide sizes originally envisaged here; d. addition of an equation for calculating the attenuation of waveguides made of any material. lEC 60153-4:2022 specifie des tubes metalliques creux rectilignes de section circulaire destines a etre utilises comme guides d’ondes dans les materiels electroniques. Le present document a pour but de specifier les guides d’ondes metalliques creux en donnant: a) les details necessaires pour assurer la compatibilite et, des lors que c’est essentiel, l’interchangeabilite; b) les methodes d’essai; c) des exigences uniformes pour les proprietes electriques et mecaniques. Le present document est destine a etre lu conjointement avec l’IEC 60153-1, qui fournit les exigences generales et les methodes d’essai. Cette quatrieme edition annule et remplace la troisieme edition parue en 2017. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a. modification du systeme de designation des petits guides d’ondes circulaires (par exemple C 25.5k au lieu de C 25500); b. revision du Tableau 1: - correction de la designation de deux guides d’ondes (desormais C 1.2k et C 12k); - correction du diametre de trois guides d’ondes (C 140, C 1.4k et C 14k); - resserrement des tolerances sur les diametres interieurs des guides d’ondes de dimensions inferieures a celles du type C 890; - suppression des valeurs d’affaiblissement des guides d’ondes pour l’aluminium, l’or et le laiton; c. suppression du Tableau 2 (duplication) et remplacement par le tableau des guides d’ondes de tailles intermediaires initialement prevu a cet emplacement; d. ajout d’une equation pour le calcul de l’affaiblissement des guides d’ondes quel que soit le materiau dont ils sont constitues.
