Environmental testing - Part 3-4: Supporting documentation and guidance - Damp heat tests (IEC 60068-3-4:2023)

IEC 60068-3-4:2023 is available as IEC 60068-3-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60068-3-4:2023 provides the necessary information and the basic principles of the effect of humidity in the context of environmental testing to assist in preparing relevant specifications, such as standards for components or equipment. Furthermore, information is provided on operating climatic test chambers. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the requirements for distilled and deionized water have been revised;
b) recommendations for the cleaning procedure of test chambers have been included;
c) humidification systems (ultrasonic humidifiers and atomizers) have been added;
d) the description of water penetration mechanisms has been refined.

Essais d'environnement - Partie 3-4: Documentation d'accompagnement et recommandations - Essais de chaleur humide (IEC 60068-3-4:2023)

IEC 60068-3-4:2023 est disponible sous forme de IEC 60068-3-4:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 60068-3-4:2023 contient les informations nécessaires et les principes de base concernant les effets de l’humidité dans le contexte des essais d'environnement pour fournir un appui à l'élaboration des spécifications pertinentes (normes pour les composants ou les matériels, par exemple). Des informations relatives au fonctionnement des chambres climatiques d'essai sont également données. Cette deuxième édition annule et remplace la première édition parue en 2001. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les exigences relatives à l'eau distillée et à l'eau déionisée ont été révisées;
b) des recommandations concernant la procédure de nettoyage des chambres d'essai ont été introduites;
c) des systèmes d'humidification (humidificateurs à ultrasons et atomiseurs) ont été ajoutés;
d) la description des mécanismes de pénétration d'eau a été affinée.
