EN 61000-4-8:2010

Electromagnetic compatibility (EMC) - Part 4-8: Testing and measurement techniques - Power frequency magnetic field immunity test

IEC 61000-4-8:2009 relates to the immunity requirements of equipment, only under operational conditions, to magnetic disturbances at power frequencies 50 Hz and 60 Hz related to: - residential and commercial locations; - industrial installations and power plants; - medium voltage and high voltage sub-stations. The applicability of IEC 61000-4-8:2009 to equipment installed in different locations is determined by the presence of the phenomenon, as specified in Clause 4. This standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation. Other IEC standards dealing with conducted disturbances cover these aspects. The object of IEC 61000-4-8:2009 is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, commercial and industrial applications when subjected to magnetic fields at power frequency (continuous and short duration field). IEC 61000-4-8:2009 defines: - recommended test levels; - test equipment; - test set-up; - test procedure. This second edition cancels and replaces the first edition published in 1993 and its Amendment 1 (2000). It forms a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the scope is extended in order to cover 60 Hz. Characteristics, performance and verification of the test generator and related inductive coils are revised. Modifications are also introduced in the test set-up (GRP) and test procedure. IEC 61000-4-8:2009 has the status of a basic EMC publication in accordance with IEC Guide 107. NEW! IEC 61000-4-8:2009 is also available as IEC Standards+ 61000-4-8:2009 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

Elektromagnetische Verträglichkeit (EMV) - Teil 4-8: Prüf- und Meßverfahren - Prüfung der Störfestigkeit gegen Magnetfelder mit energietechnischen Frequenzen

Compatibilité électromagnétique (CEM) - Partie 4-8: Techniques d'essai et de mesure - Essai d'immunité au champ magnétique à la fréquence du réseau

La CEI 61000-4-8:2009 traite des exigences en matière d'immunité des matériels, uniquement dans les conditions d'utilisation, contre les perturbations magnétiques à des fréquences de 50 Hz et 60 Hz relatives aux: - locaux résidentiels et commerciaux; - installations industrielles et centrales électriques; - postes moyenne et haute tension. Les conditions d'application de la CEI 61000-4-8:2009 aux matériels installés dans les différents secteurs sont déterminées par la présence du phénomène dans les conditions spécifiées dans l'article 4. La présente norme ne traite pas des perturbations engendrées par le couplage capacitif ou inductif sur les câbles ou autres parties de l'installation. D'autres normes CEI traitant des perturbations conduites couvrent ces aspects. La CEI 61000-4-8:2009 a pour objet d'établir une base commune et reproductible pour évaluer la performance des matériels électriques et électroniques à vocation domestique, commerciale ou industrielle lorsqu'ils sont soumis à des champs magnétiques à la fréquence du réseau (champs permanents et courte durée). La CEI 61000-4-8:2009 définit: - les niveaux recommandés d'essai; - le matériel d'essai; - l'installation d'essai; - la procédure d'essai. Cette deuxième édition annule et remplace la première édition publiée en 1993 et son amendement 1 (2000). Elle constitue une révision technique. La présente édition inclut les modification techniques majeures suivantes par rapport à la première édition: le domaine d'application est étendu de façon à couvrir le 60 Hz. Les caractéristiques, les performances et la vérification du générateur d'essai et de la bobine d'induction associée sont révisées. Des modifications sont aussi introduites dans l'installation d'essai (PS) et dans la procédure d'essai. La CEI 61000-4-8:2009 a le statut de publication fondamentale en CEM en accord avec le Guide 107 de la CEI.

Elektromagnetna združljivost (EMC) - 4-8. del: Preskusne in merilne tehnike - Preskus odpornosti proti magnetnemu polju omrežne frekvence

Ta del IEC 61000 se nanaša na zahteve glede odpornosti opreme samo pod pogoji delovanja in na magnetne motnje pri moči frekvenc 50 Hz in 60 Hz, ki se nanašajo na: - stanovanjske in gospodarske lokacije; - industrijske obrate in elektrarne; - elektronapajalne postaje srednje in visoke napetosti.  Uporaba tega standarda na opremi, ki je vgrajena na različnih lokacijah, je določena s prisotnostjo pojava, kot je določen v Klavzuli 4. Ta standard ne upošteva motenj, ki so posledica kapacitivne ali induktivne spojke v kablih ali drugih delih polja napeljave. Te vidike zajemajo drugi IEC standardi, ki obravnavajo opravljene motnje. Cilj tega standarda je vzpostavitev splošne in ponovljive osnove za ocenjevanje delovanja električne in elektronske opreme za gospodinjsko, gospodarsko in industrijsko uporabo, ko je izpostavljena magnetnim poljem  pri frekvenčni moči (neprekinjeno in kratkotrajno polje). Standard opredeljuje: - priporočene preskusne stopnje; - preskusno opremo; - preskus postavitve; - preskusni postopek.
