Anodizing of aluminium and its alloys - Determination of mass per unit area (surface density) of anodic oxidation coatings - Gravimetric method (ISO 2106:2019)
This document specifies a gravimetric method for determining the mass per unit area (surface density) of anodic oxidation coatings on aluminium and its alloys.
The method is applicable to all oxidation coatings formed by anodizing aluminium and its alloys, either cast or wrought, and is suitable for most aluminium alloys, except those in which the mass fraction of copper is greater than 6 %.
NOTE 1 A high content of copper in the alloy can lead to increased dissolution of the substrate aluminium.
NOTE 2 If the thickness is known with sufficient precision (for example, using the method specified in ISO 2128), the determination of the mass per unit area (surface density) of the coatings will enable its apparent density to be calculated. Conversely, if the conditions of application of the coating and its density are known, the determination of its mass per unit area (surface density) can permit the calculation of the average mass and an approximate evaluation of the thickness (see Clause 9).
Anodisieren von Aluminium und Aluminiumlegierungen - Bestimmung der Masse je Flächeneinheit (flächenbezogene Masse) von anodisch erzeugten Oxidschichten - Gravimetrisches Verfahren (ISO 2106:2019)
Dieses Dokument legt ein gravimetrisches Verfahren zur Bestimmung der Masse je Flächeneinheit (flächenbezogene Masse) anodisch erzeugter Oxidschichten auf Aluminium und Aluminiumlegierungen fest.
Das Verfahren ist auf alle Oxidschichten anwendbar, die durch anodische Oxidation von Aluminium, Aluminium-Guss- und -Knetlegierungen erzeugt werden. Es ist für die meisten Aluminiumlegierungen geeignet, ausgenommen für Legierungen mit einem Massenanteil an Kupfer über 6 %.
ANMERKUNG 1 Ein hoher Kupfergehalt in der Legierung kann zu einer verstärkten Auflösung des Aluminium-Trägermaterials führen.
ANMERKUNG 2 Wenn die Oxidschichtdicke mit ausreichender Genauigkeit bekannt ist (z. B. nach dem in ISO 2128, festgelegten Verfahren), ermöglicht die Bestimmung der Masse je Flächeneinheit (flächenbezogene Masse) der Oxidschicht die Berechnung ihrer scheinbaren Dichte. Sind die Bedingungen zur Aufbringung der Schicht und ihre Dichte bekannt, kann umgekehrt aus der Masse je Flächeneinheit (flächenbezogene Masse) die mittlere Masse und ein ungefährer Wert für die Schicht¬dicke errechnet werden (siehe Abschnitt 9).
Anodisation de l'aluminium et de ses alliages - Détermination de la masse surfacique (masse par unité de superficie) des couches d’oxydation anodique - Méthode gravimétrique (ISO 2106:2019)
Le présent document spécifie une méthode gravimétrique de détermination de la masse surfacique (masse par unité de superficie) des couches d'oxydation anodique sur l'aluminium et ses alliages.
Cette méthode est applicable à toutes les couches d'oxyde obtenues par anodisation sur l'aluminium et ses alliages, aussi bien sur pièces moulées que sur produits corroyés, et elle est valable pour la plupart des alliages d'aluminium, à l'exception de ceux dont la fraction massique de cuivre est supérieure à 6 %.
NOTE 1 Une forte teneur en cuivre dans l'alliage peut conduire à une dissolution excessive du substrat d'aluminium.
NOTE 2 Si l'épaisseur est connue avec une précision suffisante (par exemple au moyen de la méthode spécifiée dans l'ISO 2128), la détermination de la masse surfacique (masse par unité de superficie) des couches permettra de calculer sa masse volumique apparente. Inversement, si les conditions d'application de la couche et sa masse volumique sont connues, la détermination de sa masse surfacique (masse par unité de superficie) peut permettre le calcul de la masse moyenne et une estimation approximative de l'épaisseur (voir l'Article 9).
Anodizacija aluminija in aluminijevih zlitin - Ugotavljanje mase na enoto površine (površinska gostota) anodno oksidiranih prevlek - Gravimetrijska metoda (ISO 2106:2019)
Ta dokument določa gravimetrijsko metodo za določanje mase na enoto površine (površinske gostote) anodno oksidiranih prevlek na aluminiju in njegovih zlitinah. Metoda se uporablja za vse oksidirane prevleke, ki nastanejo z anodiziranjem aluminija in njegovih zlitin, bodisi litih ali kovanih, in je primerna za večino aluminijevih zlitin, razen tistih, pri katerih je masni delež bakra večji od 6 %.

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
