Hollow metallic waveguides - General requirements and measuring methods1 Scope This part of IEC 60153 specifies straight hollow metallic tubing for use as waveguides in electronic equipment. It covers: 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

ISO 21204 on transition specification is beneficial for:

BS EN IEC 62386-333 guides you regarding the standardization of the control interface for control gear which is intended to achieve compatible co-existence between electronic control gear and lighting control devices

particularly for different noise parameters (such as the signal-spontaneous noise factor) but it is not included in the object of BS EN 61290-3-2
