(Main)Fixed resistors for use in electronic equipment - Part 1: Generic specification
Fixed resistors for use in electronic equipment - Part 1: Generic specification
IEC 60115-1:2008 is a generic specification and is applicable to fixed resistors for use in electronic equipment. It establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications of electronic components for quality assessment or any other purpose. This standard cancels and replaces IEC 61045-1 (1991), IEC 61045-2 (1991) and IEC 61045-2-1 (1991). This edition contains the following significant technical changes with respect to the previous edition: a) implementation of Annex Q which replaces Clause 3; b) addition of new tests procedures in 4.34 through 4.38; c) removal of the property "temperature characteristics" from 4.8; d) introduction of a new system of test severities for the shear test in 4.32; e) introduction of new bias voltages for the damp heat steady-state test in 4.24; f) furthermore, this fourth edition cancels and replaces the third edition published in 1999 and constitutes minor revisions related to tables, figures and references.
Résistances fixes utilisées dans les équipements électroniques - Partie 1: Spécification générique
La CEI 60115-1:2008 est une spécification générique et s'applique aux résistances fixes utilisées dans les équipements électroniques. Elle définit les termes normalisés, les procédures d'inspection et les méthodes d'essai utilisés dans les spécifications intermédiaires et particulières des composants électroniques dans le cadre de l'assurance qualité, ainsi qu'à d'autres fins. La présente norme annule et remplace la CEI 61045-1 (1991), la CEI 61045-2 (1991) et la CEI 61045-2-1 (1991). Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) mise en place de l'Annexe Q qui remplace l'Article 3;
b) addition de nouvelles procédures d'essai de 4.34 au 4.38;
c) retrait de la propriété "caractéristiques de température" de 4.8;
d) introduction d'un nouveau système de sévérités des essais pour l'essai de cisaillement de 4.32;
e) introduction de nouvelles tensions de polarisation pour l'essai continu en chaleur humide de 4.24;
f) de plus, cette quatrième édition annule et remplace la troisième édition publiée en 1999 et ajoute des révisions mineures relatives aux tableaux, figures et références.
