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.

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 committees. 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 liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

This document was prepared by Technical Committee ISO/TC 79, Light metals and their alloys,
Subcommittee SC 2, Organic and anodic oxidation coatings on aluminium.
This third edition cancels and replaces the second edition (ISO 2376:2010), which has been technically
revised. The main changes compared with the previous edition are as follows:
— the information of the test specimen has been added;
— a withstand voltage test has been added.

Anodizing of aluminium and its alloys — Determination of
breakdown voltage and withstand voltage
1 Scope
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.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 7583, Anodizing of aluminium and its alloys — Terms and definitions
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 7583 apply.

4 Principle
The electric voltage at which current first passes through an anodic oxidation coating is measured.
These breakdown voltage and withstand voltage are a function of the dielectric characteristics and the
insulation properties of the anodic oxidation coatings. The breakdown voltage and withstand voltage
depend upon the thickness of the coating, as well as on many other factors, particularly the composition
of the basis metal, its surface condition, the effectiveness of sealing, the dryness of the test specimen
and the degree of ageing.
