IEC 60153-2:2016

IEC 60153-2:2016 specifies straight hollow metallic tubing of ordinary rectangular waveguide for use as waveguides in electronic equipment. The aim of this standard is to specify for 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. It should be noted that no recommendations are made for the materials to be used for waveguides. The choice of material is agreed between customer and manufacturer. This document should be read in conjunction with IEC 60153-1, which gives general requirements and test methods. This edition includes the following significant technical changes with respect to the previous edition:
a) expand and revise the operation frequency range for waveguides;
b) revise the allowance of aperture dimensions;
c) revise the test method for aperture dimensions;
d) revise the equation of attenuation.
