Anodizing of aluminium and its alloys - Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in acid solution(s) (ISO/DIS 3210:2024)
ISO 3210:2017 specifies methods of assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the loss of mass after immersion in acid solution(s).
It consists of the following two methods.
- Method 1: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in a phosphoric acid based solution without prior acid treatment.
- Method 2: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass after immersion in a phosphoric acid based solution with prior acid treatment.
Method 1 is applicable to anodic oxidation coatings intended for decorative or protective purposes or where resistance to staining is important.
Method 2 is applicable to anodic oxidation coatings intended for outdoor architectural purposes. For less severe applications, Method 1 can be more suitable.
The methods are not applicable to the following:
- hard-type anodic oxidation coatings which normally are not sealed;
- anodic oxidation coatings that have been sealed only in dichromate solutions;
- anodic oxidation coatings produced in chromic acid solutions;
- anodic oxidation coatings that have undergone treatment to render them hydrophobic.
NOTE 1 The methods assess the quality of hydrothermal sealing applied to anodized aluminium. They can be appropriate for other sealing methods.
NOTE 2 The methods are destructive and can serve as reference methods in case of doubt or dispute regarding the results of the test for loss of absorptive power (see ISO 2143) or the measurement of admittance (see ISO 2931).

Anodisation de l'aluminium et de ses alliages - Évaluation de la qualité des couches anodiques colmatées par mesurage de la perte de masse après immersion en solution(s) acide(s) (ISO/DIS 3210:2024)
L'ISO 3210 :2017 spécifie des méthodes d'évaluation de la qualité des couches anodiques colmatées sur aluminium et alliages d'aluminium par mesurage de la perte de masse après immersion en solution(s) acide(s).
Il comprend les deux méthodes suivantes:
- Méthode 1: Évaluation de la qualité des couches anodiques colmatées par mesurage de la perte de masse après immersion dans une solution à base d'acide phosphorique, sans traitement acide préalable;
- Méthode 2: Évaluation de la qualité des couches anodiques colmatées par mesurage de la perte de masse après immersion dans une solution à base d'acide phosphorique, avec traitement acide préalable.
La méthode 1 s'applique aux couches anodiques utilisées à des fins décoratives ou de protection ou lorsque la résistance aux taches est un facteur important.
La méthode 2 s'applique aux couches anodiques utilisées à des fins architecturales en extérieur. Pour des applications moins critiques, la méthode 1 peut se révéler plus adaptée.
Les méthodes ne sont pas applicables:
- aux couches anodiques dures qui, normalement, ne sont pas colmatées;
- aux couches anodiques qui ont été colmatées uniquement en solutions bichromatées;
- aux couches anodiques produites dans des solutions d'acide chromique;
- aux couches anodiques qui ont subi un traitement d'imperméabilisation.
NOTE 1 Les méthodes évaluent la qualité du colmatage hydrothermique appliqué à l'aluminium anodisé. Elles peuvent être appropriées pour d'autres méthodes de colmatage.
NOTE 2 Les méthodes sont destructives et peuvent servir de méthodes de référence en cas de doute ou de contestation sur les résultats des essais de perte de pouvoir absorbant (voir l'ISO 2143) ou de mesurage de l'admittance (voir l'ISO 2931).

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 World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL:

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 fifth edition cancels and replaces the fourth edition (ISO 3210:2017), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— the maximum limit for the dissolved anodic oxidation coating and aluminium content in the test solutions
A and B was reduced;
— the content of dissolved aluminium oxidation coating and aluminium in the used test solution is included
in the test report (Clause 10).

Anodizing of aluminium and its alloys — Assessment of
quality of sealed anodic oxidation coatings by measurement
of the loss of mass after immersion in acid solution(s)
1 Scope
This document specifies methods of assessing the quality of sealed anodic oxidation coatings on aluminium
and its alloys by measurement of the loss of mass after immersion in acid solution(s).
It consists of the following two methods.
— Method 1: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass
after immersion in a phosphoric acid based solution without prior acid treatment.
— Method 2: Assessment of quality of sealed anodic oxidation coatings by measurement of the loss of mass
after immersion in a phosphoric acid based solution with prior acid treatment.
Method 1 is applicable to anodic oxidation coatings intended for decorative or protective purposes or where
resistance to staining is important.
Method 2 is applicable to anodic oxidation coatings intended for outdoor architectural purposes. For less
severe applications, Method 1 can be more suitable.
The methods are not applicable to the following:
— hard-type anodic oxidation coatings which normally are not sealed;
— anodic oxidation coatings that have been sealed only in dichromate solutions;
— anodic oxidation coatings produced in chromic acid solutions;
— anodic oxidation coatings that have undergone treatment to render them hydrophobic.
NOTE 1 The methods assess the quality of hydrothermal sealing applied to anodized aluminium. They can be
appropriate for other sealing methods.
NOTE 2 The methods are destructive and can serve as reference methods in case of doubt or dispute regarding the
results of the test for loss of absorptive power (see ISO 2143) or the measurement of admittance (see ISO 2931).
