Metallic and other non-organic coatings - Sulfur dioxide test with general condensation of moisture (ISO 6988:1985)

Specifies a method for assessing the resistance of materials or products to condensed moisture containing sulfur dioxids. The method has been found to be suitable for testing metallic and non-organic coatings. Gives apparatus and material, test specimens, methods of exposure, procedure, test duration, cleaning of specimens, evaluation of results and test report.

Metallische und andere anorganische Überzüge - Prüfung mit Schwefeldioxid unter allgemeiner Feuchtigkeitskondensation (ISO 6988:1985)

Diese Internationale Norm legt ein Verfahren zur Beurteilung der Beständigkeit von Werkstoffen oder Gegenständen gegnüber kondensierter, schwefeldioxidhaltiger Feuchtigkeit fest. Es hat sich gezeigt, dass dieses Verfahren zur Prüfung metallischer und anorganischer Überzüge geeignet ist.

Revêtements métalliques et autres revêtements non organiques - Essai de soufre avec condensation générale de l'humidité (ISO 6988:1985)

La présente Norme internationale spécifie une méthode d'estimation de la résistance de matériaux ou de produits à une atmosphère contenant de l'humidité condensée et du dioxyde de soufre. La méthode convient pour l'essai des revêtements métalliques et non organiques.  
NOTE -- Pour l'essai des peintures et vernis, voir ISO 3231, Peintures et vernis -- Détermination de la résistance aux atmosphères humides contenant du dioxyde de soufre.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 6988 was prepared by Technical Committee ISO/TC 107,
