Environmental testing - Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle) (IEC 60068-2-30:2025)
IEC 60068-2-30:2025 specifies a test procedure to determine the suitability of components, equipment, or other articles for use, transportation, and storage under conditions of high humidity combined with cyclic temperature changes and, in general, producing condensation on the surface of the specimen. This test method can also be used to validate the packaging of specimen for transportation and storage.
This fourth edition cancels and replaces the third edition published in 2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) revision of the requirements for the test chamber;
b) change of the temperature tolerances of the test to limits;
c) updating of the figures for clarification purposes;
d) revision of the limits of the temperature and relative humidity during conditioning;
e) revision of the intermediate measurements;
f) revision of standardized requirements for the test report.

L'IEC 60068-2-30:2025 spécifie une procédure d'essai pour déterminer l'aptitude des composants, des équipements ou d'autres articles destinés à être utilisés, transportés ou stockés dans des conditions d'humidité élevée combinées à des variations cycliques de température et généralement à la formation de condensation à la surface des spécimens. Cette méthode d'essai peut également être appliquée pour valider l'emballage du spécimen en vue du transport et du stockage.
Cette quatrième édition annule et remplace la troisième édition parue en 2005. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) révision des exigences relatives à la chambre d'essai;
b) modification des tolérances de température de l'essai aux limites;
c) mise à jour des figures à des fins de clarification;
d) révision des limites de température et d'humidité relative pendant l'épreuve;
e) révision des mesurages intermédiaires;
f) révision des exigences normatives relatives au rapport d'essai;

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any att
