Environmental testing -- Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle)

This part of IEC 60068 determines 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. If the test is being used to verify the performance of a specimen whilst it is being transported or stored in packaging then the packaging will normally be fitted when the test conditions are being applied. For small, low mass specimens, it may be difficult to produce condensation on the surface of the specimen using this procedure; users should consider the use of an alternative procedure such as that given to IEC 60068-2-38.

Essais d'environnement -- Partie 2-30: Essais - Essai Db: Essai cyclique de chaleur humide (cycle de 12 h + 12 h)

Détermine, par essai, l'aptitude des composants, des matériels ou de tous autres articles destinés à être utilisés, transportés ou stockés dans des conditions d'humidité relative élevée combinées avec des variations cycliques de température et, en général, avec formation de condensation à la surface des spécimens. Si l'essai est utilisé pour vérifier la performance d'un spécimen lors de son transport ou de son stockage dans son emballage, alors l'emballage sera bien ajusté lorsque les conditions d'essais sont appliquées. Pour les petits spécimens, de faible masse, il peut être difficile de produire de la condensation à la surface du spécimen soumis à ce mode opératoire ; il est recommandé que les utilisateurs envisagent l'utilisation d'un mode opératoire alternatif tel qu'indiqué dans la CEI 60068-2-38. Les modifications principales par rapport à l'édition précédente sont les suivantes: - modifications éditoriales, - ajout de références normatives, - ajout de lignes directrices pour les tolérances de température, - prolongation de la période de reprise.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60068-2-30 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This third edition cancels and replaces the second edition (1980) and its amendment 1 (1985),
and constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– editorial changes,
– addition of normative references,
– addition of guidance for temperature tolerances,
– period for recovery has been extended.

Damp heat, cyclic (12 + 12-hour cycle)
INTRODUCTION
1 Scope
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. If the test is being used to
verify the performance of a specimen whilst it is being transported or stored in packaging then
the packaging shall normally be fitted when the test conditions are being applied.
2 General description
This test comprises one or more temperature cycles in which the relative humidity is
maintained at a high level.
Two variants of the cycle are given which are identical except for the temperature fall period;
during this part of the cycle, variant 2 allows wider tolerances of relative humidity and the rate
of temperature fall.
The upper temperature of the cycle and the number of cycles (see clause 4) determine the test
severity.
Test profiles illustrating the procedure are shown in Figures 1, 2a, 2b and 3.
3 Testing chamber
The chamber shall be so constructed that the conditions given hereafter may be obtained:
3.1 The temperature can be varied cyclically between 25 ± 3 °C and the appropriate upper
temperature specified with the tolerance and rate of change specified in 6.3 and Figures 2a or
2b, as applicable.
3.2 The relative humidity in the working space can be maintained within the limits given in 6.3
and in Figures 2a or 2b, as applicable.
3.3 Care shall be taken to ensure that the conditions prevailing at any point in the working
space are uniform and are as similar as possible to those prevailing in the immediate vicinity of
suitably located temperature and humidity sensing devices.  The chamber shall meet the
performance criteria as detailed in IEC 60068-3-6.
3.4 The specimens under test shall not be subjected to radiant heat from the chamber
conditioning processes.

---------------------- Page: 4 ----------------------
60068-2-30 © IEC – 5 – 104/330/CDV
3.5 Water used for the maintenance of chamber humidity shall have a resistivity of not less
than 500 Ωm.
Condensed water shall be continuously drained from the chamber and not used again until it
has been re-purified.
Precautions shall be taken to ensure that no condensed water is allowed to fall on the
specimens.
3.6 The dimensions, properties and/or electrical loading of the specimens under test shall not
appreciably influence conditions within the chamber.
4 Severities
4.1 The combination of the upper temperature and the number of cycles define the severity of
the test.
4.2 The severity shall be chosen from the fol
