EN IEC 62311:2020

Assessment of electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz to 300 GHz)

IEC 62311:2019 applies to electronic and electrical equipment for which no dedicated product standard or product family standard regarding human exposure to electromagnetic fields applies. It covers equipment with intentional or non-intentional radiators as well as a combination thereof. This document provides assessment methods and criteria to evaluate equipment against limits on exposure of people related to electric, magnetic and electromagnetic fields. The frequency range covered is from 0 Hz to 300 GHz. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This document does not specify limits expressed by means of basic restrictions and/or reference levels. Such limits are subject to the applied assessment scheme, for example by means of regional limits. This edition includes the following significant technical changes with respect to the previous edition: a) a clear distinction between intentional and unintentional radiators has been introduced; b) the exposure to non-uniform fields is considered; c) the treatment of uncertainty for the assessment procedures has been improved; d) various summation regimes are described in Annex A; e) the information from meanwhile published basic standards has been used and hence all informative annexes of the previous edition have been removed. Key words: Human Exposure, Electromagnetic Fields (0 Hz to 300 GHz).

Bewertung von elektrischen und elektronischen Einrichtungen in Bezug auf Begrenzungen der Exposition von Personen in elektromagnetischen Feldern (0 Hz bis 300 GHz)

Évaluation des équipements électroniques et électriques en relation avec les restrictions d'exposition humaine aux champs électromagnétiques (0 Hz à 300 GHz)

IEC 62311:2019 s’applique aux équipements électroniques et électriques auxquels aucune norme concernant l'exposition humaine aux champs électromagnétiques, dédiée à un produit ou à une famille de produits, ne s'applique. Il couvre les équipements à émetteurs intentionnels ou non intentionnels ainsi qu’une combinaison de ceux-ci. Le présent document fournit des méthodes et des critères d’évaluation pour démontrer que les équipements satisfont aux limites d’exposition des personnes aux champs électriques, magnétiques et électromagnétiques. La plage de fréquences couverte s’étend de 0 Hz à 300 GHz. Cette deuxième édition annule et remplace la première édition parue en 2007. Cette édition constitue une révision technique. Le présent document ne spécifie pas de limites d’exposition, ni sous la forme de restrictions de base ni sous la forme de niveaux de référence. Ces limites, exprimées par exemple sous forme de limites régionales, sont soumises au système d’évaluation appliqué. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) une distinction claire a été faite entre les émetteurs intentionnels et non intentionnels; b) l’exposition à des champs non uniformes est prise en considération; c) le traitement de l’incertitude des procédures d’évaluation a été amélioré; d) différents régimes de sommation sont décrits dans l'Annexe A; e) les informations présentes dans des normes de base publiées entre-temps ont été utilisées, ce qui explique la suppression de toutes les annexes informatives de l’édition précédente. Mots clés: exposition humaine, champs électromagnétiques (0 Hz à 300 GHz)

FOR ELECTROMAGNETIC FIELDS (0 Hz to 300 GHz)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for t
