Aluminium and aluminium alloys - Anodizing - Part 17: Determination of electric breakdown potential
This part of this European Standard specifies methods of test for the determination of the electrical breakdown potential of anodic oxidation coatings on aluminium and its alloys on flat or near-flat surfaces and on round wire. The methods are applicable to anodic oxidation coatings used primarily as electrical insulators. The methods are not applicable to coatings in the vicinity of cut edges, the edges of holes, or sharp changes of angle on, for example, extruded shapes. Note 1: The methods described do not give satisfactory results for unsealed coatings. Note 2: Electrical breakdown potential is affected by relative humidity.
Aluminium und Aluminiumlegierungen - Anodisieren - Teil 17: Bestimmung der elektrischen Durchschlagspannung
Anwendungsbereich
Dieser Teil dieser Europäischen Norm legt Prüfverfahren zur Bestimmung der elektrischen Durchschlagspannung
für anodisch erzeugte Oxidschichten auf Aluminium und Aluminiumlegierungen auf flachen oder nahezu flachen
Oberflächen und auf Runddraht fest. Die Verfahren sind auf anodisch erzeugte Oxidschichten anwendbar, die
hauptsächlich als elektrische Isolatoren verwendet werden.
Die Verfahren sind nicht auf Schichten in der Nähe von Schnittkanten, Lochkanten oder scharfkantigen Winkelüber-
gängen, z. B. an Strangpressprofilen, anwendbar.
ANMERKUNG 1 Für unverdichtete Schichten liefern die beschriebenen Verfahren keine zufriedenstellenden Ergebnisse.
ANMERKUNG 2 Die elektrische Durchschlagspannung wird durch die relative Feuchte beeinflußt.
Aluminium et alliages d'aluminium - Anodisation - Partie 17: Détermination de la tension électrique de claquage
La présente partie de cette Norme européenne spécifie les méthodes d'essai relatives a la détermination de la tension électrique de claquage des couches d'oxydation anodiques de l'aluminium et de ses alliages sur des surfaces planes ou quasi-planes ainsi que sur les fils de section circulaire. Ces méthodes s'appliquent aux couches d'oxydation anodique utilisées principalement comme isolants électriques.
Elles ne s'appliquent pas aux couches au voisinage des surfaces de coupe, bords de trous, ou changements d'angles vifs des profilés filés, par exemple.
NOTE 1 Les méthodes décrites ne fournissent pas de résultats satisfaisants pour les couches non colmatées.
NOTE 2 La tension électrique de claquage est affectée par l'humidité relative.
