Environmental testing - Part 2-10: Tests - Test J and guidance: Mould growth
Provides a test method for determining the extent to which electrotechnical products support mould growth and how any mould growth may affect the performance and other relevant properties of the product. Since mould growth conditions include high relative humidity, the test is applicable to electrotechnical products intended for transportation, storage and use under humid conditions over a period of some days at least. The main changes with respect to the previous edition are listed below: - Two test fungi replaced by two others - Concentration of the spores defined for each test fungus - Spores suspension in mineral salt solution additionally introduced - Pre-conditioning of the specimens by damp heat storage prescribed - Supersonic aerosolization of the spores suspension as the preferred inoculation method introduced - Duration of incubation reduced from 84 days to 56 days - Extent of mould growth grade 2 split into grade 2a and grade 2b - Detailed information on methods of inoculation given in Annex B - Annex E: flow-chart deleted

Fournit une méthode d'essai pour déterminer l'importance des moisissures supportées par les produits électrotechniques et la manière dont une moisissure peut compromettre la performance et les autres propriétés correspondantes du produit. Etant donné que les conditions de moisissures comprennent une humidité relative élevée, l'essai est applicable aux produits électrotechniques destinés au transport, au stockage et à l'utilisation dans des conditions humides sur une période d'au moins quelques jours. Les principaux changements par rapport à l'édition précédente sont listés ci-dessous: - Deux champignons d'essai remplacés par deux autres - Concentration des spores définie pour chaque champignon d'essai - Suspension de spores dans une solution de sels minéraux (addition) - Préconditionnement des spécimens par stockage en chaleur humide (exigence) - Production d'aérosols ultrasonores de la suspension de spores comme méthode d'inoculation privilégiée (addition) - Réduction de la durée d'incubation de 84 jours à 56 jours - Extension du grade 2 de moisissures divisé en grade 2a et 2b - Information détaillée sur les méthodes d'inoculation à l'Annexe B - Annexe E: suppression du diagramme
Okoljski preskusi - 2-10. del: Preskusi - Preskus J in navodilo: razvoj modela (IEC 60068-2-10:2005)
Ta del standarda IEC 60068 določa preskusno metodo za ugotavljanje, do kakšne mere elektrotehnični izdelki podpirajo razvoj modela in kako kakršen koli razvoj modela vpliva na delovanje in druge relevantne lastnosti izdelka.
Ker pogoji za razvoj modela vključujejo visoko relativno vlažnost, je preskus mogoče uporabiti za elektrotehnične izdelke, ki so namenjeni za prevoz, shranjevanje in uporabo v vlažnih razmerah, ki traja vsaj nekaj dni.

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 60068-2-10 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This sixth edition cancels and replaces the fifth edition published in 1988. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– Two test fungi replaced by two others
– Concentration of the spores defined for each test fungus
– Spores suspension in mineral salt solution additionally introduced
– Pre-conditioning of the specimens by damp heat storage prescribed
