EN 60738-1:2006

Thermistors - Directly heated positive temperature coefficient - Part 1: Generic specification

IEC 60738-1:2006 describes terms and methods of test for positive step-function temperature coefficient thermistors, insulated and non-insulated types typically made from ferro-electric semi-conductor materials. It establishes standard terms, inspection procedures and methods of test for use in detail specifications for Qualification Approval and for Quality Assessment Systems for electronic components. This third edition cancels and replaces the second edition published in 1998 and constitutes a minor revision. The changes with respect to the previous edition refer to the tables, figures and references.

Thermistances - Coefficient de température positif à chauffage direct - Partie 1 : Spécification générique

L'IEC 60738-1:2006 décrit des termes et des méthodes d'essais pour les thermistances à basculement à coefficient de température positif, de type isolés ou non isolés, normalement fabriqués à partir de matériaux semiconducteurs ferroélectriques. Elle établit des termes normalisés, des procédures de contrôle et des méthodes d'essais destinés aux spécifications particulières pour l'homologation et pour les systèmes d'assurance de la qualité des composants électroniques. Cette troisième édition annule et remplace la deuxième édition parue en 1998 dont elle constitue une révision mineure. Les modifications par rapport à l'édition antérieure portent sur les tableaux, les figures et les références.
