Anotation

IEC 62226-3-1:2007+A1:2016 Applies to the frequency range for which exposure limits are based on the induction of voltages or currents in the human body when exposed to electric fields. Defines in detail the coupling factor K - introduced by the IEC 62226 series to enable exposure assessment for complex exposure situations, such as non-uniform magnetic field or perturbed electric field - for the case of simple models of the human body, exposed to uniform electric fields. The coupling factor K has different physical interpretations depending on whether it relates to electric or magnetic field exposure. It is the so called "shape factor for electric field". This part of IEC 62226 can be used when the electric field can be considered to be uniform, for frequencies up to at least 100 kHz. This situation of exposure to a "uniform" electric field is mostly found in the vicinity of high voltage overhead power systems. For this reason, illustrations given in this part are given for power frequencies (50 Hz and 60 Hz). This consolidated version consists of the first edition (2007) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication. LIEC 62226-3-1:2007+A1:2016 Sapplique a la gamme de frequences pour laquelle les limites dexposition sont fondees sur des tensions ou des courants induits dans le corps humain, quand il est expose aux champs electriques. Definit le facteur de forme K - introduit par la serie CEI 62226 pour permettre levaluation de lexposition dans des situations dexpositions complexes, telles quun champ magnetique non uniforme ou un champ electrique perturbe - pour les cas de modeles simples de corps humain, expose a des champs electriques uniformes. Le facteur de couplage K peut avoir differentes interpretations physiques selon quil se refere a lexposition a un champ electrique ou magnetique. Il est aussi appele "facteur de couplage pour champ electrique". La presente partie de la CEI 62226 peut etre utilisee quand le champ electrique peut etre considere comme uniforme, pour des frequences jusqua au moins 100 kHz. Cette situation dexposition a un champ electrique "uniforme" se trouve principalement a proximite des systemes aeriens dalimentation electrique a haute tension. Pour cette raison, les illustrations donnees dans cette section sont aux frequences industrielles (50 Hz et 60 Hz). Cette version consolidee comprend la premiere edition (2007) et son amendement 1 (2016). Il nest donc pas necessaire de commander lamendement avec cette publication.
