The methods described are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but only with similar colours.

This document specifies the chemical composition limits for aluminium casting alloys and mechanical properties of separately cast test pieces for these alloys.
Annex C is included as a guide to the selection of alloys for a specific use or process.

This document specifies a method for the determination of the surface abrasion resistance of anodic oxidation coatings produced by sulfuric acid anodizing of aluminium and its alloys. It is mainly intended for the evaluation of external architectural coatings. It is a production control method that relies to a large extent on operator experience and instruction.

This document defines the requirements for grades of alloyed aluminium ingots intended for remelting.
It specifies the classifications and designations applicable to these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

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).

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.

This document describes the criteria and the procedure for analysing aluminium and aluminium alloys with spark optical emission spectrometry (S-OES). The scope of this document covers the following:
-   sample preparation;
-   operational guidelines for an optical emission spectrometer (including maintenance);
-   traceability of the analytical results to the International System of units: mass (kg);
-   assessing the uncertainty associated with each analytical result.
This document refers to simultaneous spark emission spectrometers for the analysis of solid samples.
It applies to the determination of silicon, iron, copper, manganese, magnesium, chromium, nickel, zinc, titanium, boron, gallium, vanadium, beryllium, bismuth, calcium, cadmium, cobalt, lithium, sodium, phosphorus, lead, antimony, tin, strontium and zirconium in aluminium and aluminium alloys.
Elements other than those listed above may be analysed on the condition that:
a) suitable reference materials are available; and
b) the instrument is suitably calibrated and equipped.
In the case of determining mercury, for compliance purposes an alternate method with a limit of quantification < 0,000 1 % is recommended as its detection is compromised by intense iron interference at 253,65 nm.
The test result obtained from a spark optical emission spectrometer generally concerns an amount of less than one milligram per spark spot. The result can be used to refer to the laboratory test sample, to the aluminium or aluminium alloy melt or to the cast product.

This document specifies an empirical method for assessing the resistance of anodic oxidation coatings to cracking by deformation.
The method is applicable particularly to sheet material with anodic oxidation coatings of thickness less than 5 µm, and is useful for development purposes.

—          exposure to corrosive environments, and
—          practical service tests.
This document takes into account only pitting corrosion resulting from penetration of the protective anodic oxidation coating.

This document specifies a comparative method for the determination of the fastness of coloured anodic oxidation coatings to ultraviolet (UV) light and heat.

The use of this method is limited to anodic oxidation coatings of thickness less than 5 µm or coatings that have been deformed, which includes those produced by coil anodizing techniques.
NOTE       The method described enables a rapid check to be made for the continuity of a thin coating of aluminium oxidation on aluminium and its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating that exposes bare metal.

This document specifies the following tests:
a)    abrasive-wheel-wear test, determining the abrasion resistance of anodic oxidation coatings with abrasive wheel on flat specimens of aluminium and its alloys;

ISO 10215:2018 specifies a visual method for determining the image clarity of anodic oxidation coatings on aluminium and its alloys, using a chart scale and a lightness scale, which are defined. The method is applicable only to flat surfaces that can reflect the image of the chart scale pattern.

ISO 7599:2018 specifies a method for specifying decorative and protective anodic oxidation coatings on aluminium (including aluminium-based alloys). It defines the characteristic properties of anodic oxidation coatings, lists methods of test for checking the characteristic properties, provides minimum performance requirements, and gives information on the grades of aluminium suitable for anodizing and the importance of pretreatment to ensure the required appearance or texture of the finished work.
It is not applicable to
a)    non-porous anodic oxidation coatings of the barrier layer type,
b)    anodic oxidation coatings produced by chromic acid or phosphoric acid anodizing,
c)    anodic oxidation coatings intended merely to prepare the substrate for subsequent application of organic coatings or for the electrodeposition of metals, and
d)    hard anodic oxidation coatings used mainly for engineering purposes, for which abrasion and wear resistance are the primary characteristics (see ISO 10074).

ISO 2931:2017 specifies a method for assessing the quality of sealed anodic oxidation coatings on aluminium and its alloys by measurement of the admittance.
The method is applicable to anodic oxidation coatings sealed in an aqueous medium.
NOTE 1    Results obtained from anodic oxidation coatings sealed by different methods, e.g. hydrothermal sealing and cold sealing, are not necessarily comparable.
NOTE 2    Results obtained from anodic oxidation coatings on alloys containing more than 2 % silicon or 5 % manganese or 3 % magnesium are not comparable with results obtained from anodic oxidation coatings on more dilute alloys.
The method is suitable for use as a production-control test and as an acceptance test where there is agreement between the anodizer and the customer.
Any type of anodized component can be tested by the method described, provided that there is a sufficient area (a circle of diameter about 20 mm) and that the film thickness is greater than 3 µm.

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).

ISO 2143 specifies a method of estimating the loss of absorptive power of anodic oxidation coatings that have undergone a sealing treatment, by dye absorption after acid pretreatment.
The method is suitable for use as a production control method and can be applicable to anodic oxidation coatings which may be subjected to weathering or aggressive environments, or where resistance to staining is important.
The method is not applicable to those coatings that
a)    are formed on alloys containing more than 2 % copper or 4 % silicon,
b)    are sealed by the dichromate process,
c)    have been given supplementary processing, e.g. oiling, waxing or lacquering,
d)    are coloured in deep shades, and
e)    are less than 3 μm thickness.
The method is less appropriate where nickel or cobalt salts, or organic additives, have been added to baths used for hydrothermal sealing.
