Anodizing of aluminium and its alloys - Determination of breakdown voltage and withstand voltage (ISO 2376:2019)

This document specifies test methods for the determination of the breakdown voltage and withstand voltage 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    Breakdown voltage and withstand voltage are affected by relative humidity.
NOTE 2    The methods described do not give satisfactory results for unsealed coatings because they are affected by the humidity in particular.

Anodisieren von Aluminium und Aluminiumlegierungen - Bestimmung der Durchschlagspannung und der Spannungsfestigkeit (ISO 2376:2019)

Dieses Dokument legt Prüfverfahren zur Bestimmung der Durchschlagspannung und Spannungsfestigkeit 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 Winkelübergängen, z. B. an Strangpressprofilen, anwendbar.
ANMERKUNG 1   Durchschlagspannung und Spannungsfestigkeit werden durch die relative Luftfeuchte beeinflusst.
ANMERKUNG 2   Für unverdichtete Schichten liefern die beschriebenen Verfahren keine zufriedenstellenden Ergebnisse, weil sie insbesondere durch die relative Luftfeuchte beeinflusst werden.

Anodisation de l'aluminium et de ses alliages - Détermination de la tension de claquage et tension de tenue (ISO 2376:2019)

Le présent document spécifie des méthodes d'essai relatives à la détermination de la tension de claquage et de la tension de tenue des couches 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 anodiques utilisées principalement comme isolants électriques.
Ces méthodes ne s'appliquent pas aux couches au voisinage des surfaces de coupe, des bords de trous ou des changements d'angles vifs des profilés filés, par exemple.
NOTE 1    La tension de claquage et la tension de tenue sont influencées de manière néfaste par l'humidité relative.
NOTE 2    Les méthodes décrites ne fournissent pas de résultats satisfaisants pour les couches non colmatées car elles sont influencées de manière néfaste par l'humidité, notamment.

Anodizacija aluminija in aluminijevih zlitin - Ugotavljanje električne prebojne napetosti (ISO 2376:2019)

V tem dokumentu so navedene preskusne metode za določanje električne prebojne napetosti anodno oksidiranih plasti na aluminiju in njegovih zlitinah, na ravnih ali skoraj ravnih površinah in na okrogli žici. Te metode se uporabljajo za anodno oksidirane plasti, ki se uporabljajo predvsem kot električni izolatorji.
Te metode se ne uporabljajo za plasti v bližini odrezanih robov, robov lukenj ali ostrih sprememb kota, na primer pri ekstrudiranih oblikah.
OPOMBA 1: Električna prebojna napetost je odvisna od relativne vlažnosti.
OPOMBA 2: Opisane metode ne dajejo zadovoljivih rezultatov za nezatesnjene plasti, ker nanje vpliva še zlasti vlaga.
