Anotation

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. IEC 61000-4-8:2009 traite des exigences en matiere dimmunite des materiels, uniquement dans les conditions dutilisation, contre les perturbations magnetiques a des frequences de 50 Hz et 60 Hz relatives aux: - locaux residentiels et commerciaux; - installations industrielles et centrales electriques; - postes moyenne et haute tension. Les conditions dapplication de la CEI 61000-4-8:2009 aux materiels installes dans les differents secteurs sont determinees par la presence du phenomene dans les conditions specifiees dans larticle 4. La presente norme ne traite pas des perturbations engendrees par le couplage capacitif ou inductif sur les cables ou autres parties de linstallation. Dautres normes CEI traitant des perturbations conduites couvrent ces aspects. La CEI 61000-4-8:2009 a pour objet detablir une base commune et reproductible pour evaluer la performance des materiels electriques et electroniques a vocation domestique, commerciale ou industrielle lorsquils sont soumis a des champs magnetiques a la frequence du reseau (champs permanents et courte duree). La CEI 61000-4-8:2009 definit: - les niveaux recommandes dessai; - le materiel dessai; - linstallation dessai; - la procedure dessai. Cette deuxieme edition annule et remplace la premiere edition publiee en 1993 et son amendement 1 (2000). Elle constitue une revision technique. La presente edition inclut les modification techniques majeures suivantes par rapport a la premiere edition: le domaine dapplication est etendu de facon a couvrir le 60 Hz. Les caracteristiques, les performances et la verification du generateur dessai et de la bobine dinduction associee sont revisees. Des modifications sont aussi introduites dans linstallation dessai (PS) et dans la procedure dessai. La CEI 61000-4-8:2009 a le statut de publication fondamentale en CEM en accord avec le Guide 107 de la CEI.
