EN IEC 62764-1:2022

Measurement procedures of magnetic field levels generated by electronic and electrical equipment in the automotive environment with respect to human exposure - Part 1: Low-frequency magnetic fields

IEC 62764-1:2022 specifies a methodology for determining the exposure to multiple magnetic field sources for passenger cars and light commercial vehicles including standardized operating conditions and measurement volumes and/or surfaces. This part of IEC 62764 applies to the assessment of human exposure to low-frequency magnetic fields generated by automotive vehicles. For plug-in vehicles, this includes the electric vehicle supply equipment (EVSE) and associated cables provided by the car manufacturer. This excludes the charging station. This document specifies the measurement procedure for the evaluation of magnetic field exposures generated by electronic and electrical equipment (excluding intentionally transmitting radio frequency antennas) in selected automotive environments, for passenger cars and commercial vehicles of categories M1 and N1 as defined in ECE/TRANS/WP.29/78/Rev.3 [1], with respect to human exposure. It provides standardized operating conditions and defines recommended measurements to assess compliance with the applicable exposure requirements. This document covers the frequency range 1 Hz to 100 kHz and is applicable to any type of engine and/or internal energy source.

Procédures de mesure de l'exposition humaine aux niveaux de champs magnétiques générés par les accessoires électroniques et électriques dans l'environnement automobile - Partie 1: Champs magnétiques à basse fréquence

L'IEC 62764-1:2022 spécifie une méthodologie pour déterminer l’exposition à plusieurs sources de champs magnétiques pour les voitures particulières et les véhicules utilitaires légers, y compris les conditions de fonctionnement normalisées et les volumes et/ou surfaces de mesure. La présente partie de l'IEC 62764 s’applique à l’évaluation de l’exposition humaine aux champs magnétiques à basse fréquence générés par les véhicules automobiles. Pour les véhicules rechargeables, cela inclut l’équipement d’alimentation des véhicules électriques (EVSE) et les câbles associés fournis par le constructeur automobile. Cela exclut la station de charge. Le présent document spécifie la procédure de mesure pour l’évaluation des expositions aux champs magnétiques générées par les équipements électroniques et électriques (à l’exclusion des antennes de radiofréquence émettant intentionnellement) dans certains environnements automobiles, pour les voitures particulières et les véhicules utilitaires des catégories M1 et N1 telles que définies dans la norme ECE/TRANS/WP.29/78/Rev.3 [1][1], en ce qui concerne l’exposition humaine. Il fournit des conditions de fonctionnement normalisées et définit les mesures recommandées pour évaluer la conformité aux exigences applicables en matière d’exposition. Le présent document couvre la gamme de fréquences de 1 Hz à 100 kHz et s’applique à tout type de moteur et/ou de source d’énergie interne.
