Electromagnetic compatibility (EMC) - Part 4-31: Testing and measurement techniques - AC mains ports broadband conducted disturbance immunity test
IEC 61000-4-31:2016 relates to the conducted immunity of electrical and electronic equipment to electromagnetic disturbances coming from intended and/or unintended broadband signal sources in the frequency range 150 kHz up to 80 MHz. It has the status of a basic EMC publication in accordance with IEC Guide 107.

Compatibilité électromagnétique (CEM) - Partie 4-31: Techniques d'essai et de mesure - Essai d'immunité aux perturbations conduites à large bande sur les accès d'alimentation secteur en courant alternatif
L'IEC 61000-4-31:2016 se rapporte à l'immunité en conduction des matériels électriques et électroniques aux perturbations électromagnétiques provoquées par des sources de signaux à large bande volontaires et/ou involontaires dans la plage de fréquences de 150 kHz à 80 MHz. Elle a le statut d'une publication fondamentale en CEM conformément au Guide IEC 107.
Elektromagnetna združljivost (EMC) - 4-31. del: Preskusne in merilne tehnike - Preskus odpornosti konektorjev izmeničnega napajanja proti širokopasovnim motnjam po vodnikih
Ta del standarda IEC 61000 se nanaša na prevodno odpornost električne in elektronske opreme na elektromagnetne motnje, ki jih povzročajo predvideni in/ali nepredvideni viri širokopasovnih signalov v frekvenčnem območju od 150 kHz do 80 MHz.
Namen tega standarda je določiti skupno referenco za vrednotenje odpornosti električne in elektronske opreme, izpostavljene prevodnim motnjam, ki jih povzročajo predvideni in/ali nepredvideni viri širokopasovnih signalov pri konektorjih izmeničnega napajanja. Preskusna metoda, dokumentirana v tem standardu, opisuje skladno metodo za oceno odpornosti opreme ali sistema proti opredeljenemu pojavu.
Oprema, ki ne vključuje vsaj enega konektorja izmeničnega napajanja, ni zajeta. Napajalni konektorji, ki niso namenjeni za povezavo z razdelilnimi omrežji izmeničnega napajanja, se ne obravnavajo kot »konektorji izmeničnega napajanja« in so zato izključeni.
Ta standard se uporablja samo za enofazno opremo z nazivnim vhodnim tokom ≤ 16 A in ne obravnava učinkov širokopasovnih motenj na večfazno opremo in/ali opremo z nazivnim vhodnim tokom > 16 A.
OPOMBA: Ta standard je osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC), kot je opisano v vodilu 107 Mednarodne elektrotehniške komisije. Poleg tega je v vodilu 107 navedeno, da so tehnični odbori v okviru Mednarodne elektrotehniške komisije odgovorni za določitev morebitne uporabe tega standarda s preskusom odpornosti, v primeru uporabe pa so odgovorni za določitev ustreznih preskusnih ravni in meril učinkovitosti. Odbor TC 77 in njegovi pododbori so pripravljeni za sodelovanje s tehničnimi odbori pri vrednotenju posameznih preskusov odpornosti za ustrezne izdelke.
