Vitreous and porcelain enamels - Low voltage test for detecting and locating defects (ISO 8289:2000)
Two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings.
Emails und Emaillierungen - Niedrigspannungsprüfung zum Nachweis und Lokalisieren von Fehlstellen (ISO 8289:2000)
Anwendungsbereich
Diese Internationale Norm legt zwei Niedrigspannungsprüfungen zum Nachweis und Lokalisieren von Fehlstellen in Email-Überzügen, die bis zum Grundmetall durchgehen, fest.
Verfahren A (elektronisches Verfahren) ist geeignet für den raschen Nachweis und die Grobbestimmung der Lage der Fehlstellen. Verfahren B (optisches Verfahren), das auf Farbeffekten beruht, ist geeignet für den präziseren Nachweis von Fehlstellen und ihrer exakten Lage. Verfahren A wird gewöhnlich für ebene Oberflächen angewendet, wogegen Verfahren B für kompliziertere Formen bevorzugt wird.
ANMERKUNG 1 Die Auswahl des richtigen Prüfverfahrens zur Unterscheidung von Bereichen erhöhter Leitfähigkeit, die mit dem Verfahren B nachgewiesen wurden, von vorhandenen Poren, die bis zum Grundmetall durchgehen und mit beiden Verfahren nachgewiesen werden können, ist kritisch.
ANMERKUNG 2 Die Niedrigspannungsprüfung ist ein zerstörungsfreies Verfahren für den Nachweis von Fehlstellen (siehe Abschnitt 3) und ist daher vollständig verschieden im Vergleich zur Hochspannungsprüfung nach ISO 2746. Die Ergebnisse von Hoch- und Niedrigspannungsprüfungen sind nicht vergleichbar und abweichend voneinander.
Emaux vitrifiés - Essai à basse tension pour la détection et la localisation des défauts (ISO 8289:2000)
La présente Norme internationale spécifie deux méthodes d'essai à basse tension permettant de détecter et de localiser les défauts s'étendant jusqu'au métal de base sur les articles en émail vitrifié. La méthode A (électrique) convient pour une détection rapide et une localisation globale des défauts. La méthode B (optique), basée sur des effets de couleur convient pour une détection sensible et une localisation exacte des défauts. La méthode A est généralement appliquée aux surfaces planes, tandis que la méthode B est recommandée pour des formes plus complexes.
NOTE 1 Le choix de la méthode d'essai appropriée est essentiel pour distinguer les zones de conductivité accrue détectées par la méthode B, des pores effectifs qui s'étendent jusqu'au métal de base, lesquels peuvent être détectés par les deux méthodes.
NOTE 2 L'essai à basse tension est une méthode d'essai non destructif permettant la détection des défauts (voir article 3), et n'a donc rien à voir avec l'essai à haute tension spécifié dans l'ISO 2746. Il n'est par conséquent pas possible de comparer les résultats des essais des deux méthodes.

This European Standard was approved by CEN on 24 June 2001.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical com-
mittees. Each 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, governmental and non-governmental, in liai-
son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 8289 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic
coatings.
This second edition cancels and replaces the first edition (ISO 8289:1986), which has been technically revised.
