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.

ENVIRONMENTAL TESTING –
Part 2–10: Tests – Test J and Guidance: Mould growth
1 Scope
This part of IEC 60068 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.
