Flanges for waveguides - General requirements1 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 should 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

Cables are usually known to transmit electric energy

have semiconductor switching element(s) and are intended to be connected to circuits

Cables with galvanized steel pliable wire armouring having individually metallic screened or unscreened cores and a rated voltage 3800/6600 V

and supports essential requirements of EU Directive 97/23/EC for pressure equipment (PED)

6) Zinc-coated-steel with or without organic coating

— personal protective equipment covered by Directive 89/686/EEC

liquid and gaseous fuels and non-sootfire resistant chimneys

This new standard will be most valuable to groups of peers performing conformity assessment activities
