Environmental testing - Part 2-38: Tests - Test Z/AD: Composite temperature/humidity cyclic test

IEC 60068-2-38:2021 is available as IEC 60068-2-38:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60068-2-38:2021 specifies a composite test procedure, primarily intended for component type specimens, to determine, in an accelerated manner, the resistance of specimens to the deteriorative effects of high temperature/humidity and cold conditions. This test standard does not apply to specimens that are energized during the complete test. Specimens can be energized during the constant phases of the tests. Measurements on energized specimens are typically carried out during constant phases of the test unless specified otherwise. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the figures have been updated; - changes to the wording has been made for clarification purposes.

Essais d'environnement - Partie 2-38: Essais - Essai Z/AD: Essai cyclique composite de température et d'humidité

IEC 60068-2-38:2021 est disponible sous forme de IEC 60068-2-38:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60068-2-38:2021 spécifie une procédure d'essai composite, essentiellement destinée aux spécimens de type composant, dans le but de déterminer d'une manière accélérée la résistance des spécimens aux effets destructifs dus à des séjours dans des conditions de température/d'humidité élevées, alternées avec des conditions de froid. La présente norme d'essai ne s'applique pas aux spécimens qui sont mis sous tension durant toute la durée de l'essai. Les spécimens peuvent être mis sous tension durant les phases constantes des essais. Les mesures réalisées sur des spécimens sous tension ont généralement lieu durant les phases constantes de l'essai, sauf spécification contraire. Cette troisième édition annule et remplace la deuxième édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente - les figures ont été mises à jour; - la formulation a été modifiée à des fins de clarification.
