Fixed resistors for use in electronic equipment - Part 8-1: Blank detail specification: Fixed surface mount resistors categorized as level G - Assessment level EZ

SIST EN 60115-8-1 specifies the characteristics and ratings of fixed surface mount (SMD) resistors. The resistors covered herein are classified to level G, as defined in IEC 60115-8-1, 1.5 for general electronic equipment, typically operated under benign or moderate environmental conditions, where the major requirement is function. Examples for level G include consumer products and telecommunication user terminals.

Résistances fixes utilisées dans les équipements électroniques - Partie 8-1: Spécification particulière cadre: Résistances fixes pour montage en surface classées dans la catégorie de niveau G - Niveau d'assurance EZ

L'IEC 60115-8-1:2014 s'applique à la rédaction des spécifications particulières pour des résistances fixes à couche et à faible dissipation pour montage en surface (CMS) en forme de puce rectangulaire (modèle RR) ou sans sorties à électrodes métalliques (MELF) de forme cylindrique (modèle RC), classées dans la catégorie de niveau G qui est définie dans l'IEC 60115-8:2009, 1.5, pour les équipements électroniques universels, fonctionnant typiquement dans des conditions d'environnement douces ou modérées, où la principale exigence est de fonctionner. Le niveau G inclut par exemple des produits de grande consommation et des terminaux de télécommunication pour utilisateurs. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Des révisions mineures liées aux tableaux, figures et références y ont été introduites.
- Dédicace à des résistances de niveau G de classification de produit qui est pour les équipements électroniques universels, généralement exploité dans des conditions environnementales bénignes ou modérées, comme par exemple les produits de consommation, ou les terminaux de télécommunication pour utilisateurs.
- Mise en oeuvre de la politique de zéro défaut avec l'application du seul niveau d'assurance EZ dans tous les programmes d'essais.
- Remplacement du coefficient de température de la résistance (TCR), spécifié sur toute la plage de température définie, pour les caractéristiques de température inférieures et moins importantes.
- Ajout d'un essai d'immunité contre les décharges électrostatiques.
- Mise en oeuvre de la notion de classes de stabilité avec les exigences coordonnées à la performance à tous les essais prescrits.
- Ajout d'informations pertinentes pour l'utilisateur du composant dans son processus d'assemblage.
- Ajout d'une annexe fournissant des dispositions spéciales pour les résistances de 0 (câble de liaison), qui peuvent faire partie d'une gamme de produits couverte par une spécification particulière dérivée de la présente spécification particulière cadre.

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
