Classification of environmental conditions - Part 3-9: Classification of groups of environmental parameters and their severities - Microclimates inside products (IEC 60721-3-9:2024)
IEC 60721-3-9:2024 classifies groups of microclimatic conditions, to which components (basic parts, assemblies, built-in units) can be subjected inside products, which are used under the climatic conditions as classified in IEC 60721-3-3 and IEC 60721-3-4.
This second edition cancels and replaces the first edition published in 1993, Amendment 1:1994 and Corrigendum 1:1995. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Clause 2 has been updated;
b) Clause 4 has been re-edited and simplified;
c) Annex A has been revised and updated;
d) a new Annex B has been added and gives the origin of the constitutional diagram for humid air, which is the basis of drawing the climatogram for a microclimate.

Classification des conditions d'environnement - Partie 3-9: Classification des groupements des agents d'environnement et de leurs sévérités - Microclimats à l'intérieur des produits (IEC 60721-3-9:2024)
L'IEC 60721-3-9:2024 classifie les groupements des conditions microclimatiques auxquelles les composants (parties élémentaires, assemblées, encastrées) peuvent être soumis à l'intérieur des produits, lorsqu'ils sont utilisés dans les conditions climatiques classifiées dans l'IEC 60721-3-3 et l'IEC 60721-3-4.
Cette deuxième édition annule et remplace la première édition parue en 1993, l’Amendement 1:1994 et le Corrigendum 1:1995. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) l’Article 2 a été mis à jour;
b) l’Article 4 a été reformulé et simplifié;
c) l’Annexe A a été révisée et mise à jour;
d) une nouvelle Annexe B a été ajoutée et fournit l'origine du diagramme constitutionnel pour l'humidité de l'air, qui sert de base à l'établissement du climatogramme d'un microclimat.
