This document specifies requirements for resistance spot welding in the fabrication of assemblies of
aluminium sheet, extrusions (both work- and age-hardening alloys) and/or cast material comprising
two or three thicknesses of metal, where the maximum single (sheet) thickness of components to be
welded is within the range 0,6 mm to 6 mm.
This document is applicable to the welding of sheets or plates of dissimilar thickness where the
thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses where the total
thickness is less than or equal to 9 mm.
Welding with the following types of machines is within the scope of this document:
— pedestal welding machines;
— gun welders;
— automatic welding equipment where the components are fed by robots or automatic feeding
equipment;
— multi-welders;
— robotic welders.
Information on appropriate welding equipment is given in Annex A and on spot welding conditions in
Annex B. The latter are for guidance only and can require modification depending on service conditions
of the fabrication, type of welding equipment, characteristics of the secondary circuit, electrode
material and geometry.
The welding of coated material, e.g. zinc-coated or anodized material, is outside the scope of this
document.

This document describes the criteria and operation procedure for carrying out spark optical emission spectrometry (S-OES) on metal samples. The scope of this standard covers the following:
-   sample preparation;
-   operational guidelines for an optical emission spectrometer (including self-maintenance);
-   traceability of the analytical results to the international base 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 uses a sampling mass 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 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).

coatings that have undergone a sealing treatment, by dye absorption after acid pretreatment.

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

This European Standard defines general terms relating to products of aluminium and aluminium alloys which are helpful for communication within the aluminium industry and with its customers . It includes terms dealing with aluminium products, processing, sampling and testing, product characteristics and different types of visual quality characteristics. It does not include terms dealing with bauxite mining, alumina and anode production and aluminium smelting. This European Standard tries to adhere as closely as possible to the terms and definitions used in other standards or documents. This European Standard tries to follow the "common language" as it is used in native English speaking countries, without giving preference to specific idioms of any one of these counties. In cases where in different English-speaking countries different terms are used for the same concept or different concepts refer to an identical term, the appropriate explanations are given.

This International Standard specifies a non-destructive method for determining the thickness of anodic oxidation coatings on aluminium and its alloys using a split-beam microscope. The method is applicable, in most industrial cases, to anodic oxidation coatings above 10 μm, or above 5 μm when the surface is smooth. The use of the method specified is limited by the need for the two luminous lines described in Clause 3 to be visible and distinctly separated, i.e. not in the case of opaque or dark-coloured coatings.

This International Standard specifies a method of measuring the total and diffuse luminous reflectance characteristics of aluminium surfaces, using integrating-sphere instruments. The method described is also applicable to the measurement of specular reflectance (principal gloss value), specularity and diffuseness. The method is unsuitable for use with lighting reflectors.
