Corrigendum 2 - Appareillage à basse tension - Partie 1: Règles générales
IEC 60947-1:2020 Lorsque la norme de produit correspondante l’exige, le présent document s’applique à l’appareillage basse tension ci-après désigné comme le “matériel” ou le “dispositif”, et destiné à être relié à des circuits dont la tension assignée ne dépasse pas 1 000 V en courant alternatif. ou 1 500 V en courant continu.
Le présent document a pour objet de fixer les règles générales et exigences de sécurité communes des appareillages basse tension, y compris:
– les définitions,
– les caractéristiques,
– les informations fournies avec le matériel,
– les conditions normales de service, de montage, de transport, de mise hors service et de démontage,
– les exigences relatives à la construction et au fonctionnement,
– la vérification des caractéristiques et du fonctionnement,
– les aspects liés à l’efficacité énergétique (voir Annexe V),
– les aspects environnementaux.
Cette sixième édition annule et remplace la cinquième édition parue en 2007, l'Amendement 1:2010 et l'Amendement 2:2014. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
– amélioration des essais relatifs aux valeurs en courant continu,
– mise à jour des essais de CEM,
– suppression de l’Annexe B,
– mise à jour des exigences des essais d’environnement (Tableau Q.1),
– amélioration de l’Annexe R (nouveaux exemples),
– suppression du type d’entrée numérique 2 et insertion du type 3 dans l’Annexe S,
– insertion d’un exemple de déclaration de matière dans l’Annexe W,
– création d’une nouvelle Annexe X (coordination des dispositifs de protection contre les courts-circuits associés dans un même circuit).
Le contenu du corrigendum de décembre 2022 a été pris en considération dans cet exemplaire.
