Annotation of standard text IEC 60738-1-ed.4.0 :

IEC 60738-1:2022 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 edition includes the following significant technical changes with respect to the previous edition: a) Restructured completely to comply with ISO/IEC Directives; categorization and reorganization of test methods into these categories; b) Some wordings, figures and references have been revised. L’IEC 60738-1:2022 decrit des termes et des methodes d’essai pour les thermistances a basculement a coefficient de temperature positif, de type isolees ou non isolees, normalement fabriquees a partir de materiaux semiconducteurs ferroelectriques. Elle etablit des termes normaux, des procedures de controle et des methodes d’essai destines aux specifications particulieres pour l’homologation et pour les systemes d’assurance de la qualite des composants electroniques. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) restructuration complete pour etre conforme aux Directives ISO/IEC; categorisation et reorganisation des methodes d’essai dans ces categories, b) revision de certaines formulations, figures et references.
