application standard (see Annex A);
e) reference to the standard for tolerances of form and dimensions (e.g. EN 485-3, EN 485-4 or as disclosed
in any application standard (see Annex A));
f) dimensions of the product:
— thickness;
— width;
— length of sheet and plate, as applicable (in the rolling direction);
— internal and external diameters of the coil, or dimension and type of the core, as applicable.
NOTE 1 Unless otherwise agreed, the length is the largest dimension of the sheet or plate and corresponds to the
rolling direction.
g) quantity:
— mass or number of pieces;
— quantity tolerances if required;
h) any requirements for inspection documents;
i) any other test, in addition to chemical analysis and tensile testing;
j) any additional requirements, such as:
— quality assurance;
— specific inspection schemes;
— marking of products;
— references of drawing, etc.;
— special packing requirements;
k) for products intended for decorative anodizing by the purchaser, the order document shall also contain
the following:
— statement that the product is intended to be anodized;
— intended particular surface treatment (according to the relevant standard);
— whether a decorative appearance after anodizing is required for both sides and, if only one side, its
position with respect to the strip (inside or outside of the coil) or the sheet or plate (upside or
downside).
Products intended to form a specific area after anodizing (such as a façade) should be ordered in a single batch.
The order document should indicate the intended application.
NOTE 2 The codification scheme specified in EN 573-5 will preferably be used.
5 Requirements
5.1 Production and manufacturing processes
Unless otherwise specified in the order document, the production and manufacturing processes shall be left
to the discretion of the manufacturer. Unless it is explicitly stated in the order document, no obligation shall
be placed on the manufacturer to use the same processes for similar and subsequent orders.
5.2 Quality Control
The supplier shall be responsible for the performance of all inspection and tests required by the relevant
European Standard and/or the particular specification prior to shipment of the product. If the purchaser
wishes to inspect the product at the manufacturer’s works, he shall notify the supplier at the time of placing
the order.
5.3 Requirements on product properties
5.3.1 Chemical composition
The chemical composition shall comply with the requirements as specified in EN 573-3.
If the purchaser requires content limits for elements not specified in the above standard, these limits shall be
stated in the order document.
5.3.2 Mechanical properties
The mechanical properties determined by the tensile test shall be in conformity with those specified in
EN 485-2, if not otherwise stated in the order document. Other properties such as hardness, bending ability,
isotropy, etc. can be specified in the order document.
5.3.3 Corrosion behaviour
Products made of 5xxx alloys with nominal magnesium content equal to or higher than 3 % in the H116 and
H321 tempers shall be capable of exhibiting no exfoliation corrosion susceptibility according to ASTM G66
accelerated test and inter-granular corrosion susceptibility according to ASTM G67. The release criteria for
these tests are described in EN 13195.
Plate exhibit made of alloys EN AW-7010 and EN AW-7075 in the T73 and T7351 tempers and over 25 mm in
thickness, shall exhibit no evidence of stress-corrosion cracking when tested in accordance with ASTM G47 or
in ISO 9591.
Products made of alloys EN AW-7010 and EN AW-7075 in the tempers T76 and T7651 shall be capable of
exhibiting no evidence of exfoliation corrosion in excess of grade EB, as defined in ASTM G34, when subjected
to the test specified in 6.10.2.
5.3.4 Freedom from defects
The product shall be free from defects prejudicial to its suitable and proper use.
It shall have a smooth and clean surface. However small surface imperfections such as light scratches,
indentations, laminations, stripes, roll marks, discolorations and non-uniform surface appearance resulting
from heat treatment, etc., which cannot always be totally avoided, are generally permitted on both sides of the
product.
Whilst an operation designed to mask a defect is not permitted, superficial defects may be eliminated,
provided that the dimensional tolerances and material properties continue to meet the specifications.
For products intended for decorative anodizing, the superficial imperfections (discolouration, mechanical or
structural imperfections) might not be so extensive as to impair the decorative appearance after the agreed
surface treatment. Limiting samples can be agreed between supplier and purchaser.
5.3.5 Tolerances on dimensions and form
The dimensions and form tolerances shall be in conformity with EN 485-3 and EN 485-4, unless otherwise
agreed upon between supplier and purchaser and stated in the order document. Unless otherwise agreed
upon, the purchaser may reject only those products having dimensions not complying with the specified
tolerances.
5.3.6 Other properties
Any additional product requirements shall be defined and stated in the purchase order. For requirements
coming from application Standards, the requirements shall be those mentioned in the applicable Standards
listed in Annex A.
6 Test methods
6.1 General
If the purchaser wishes to inspect the product at the supplier's works, the purchaser shall notify the supplier
at the time of placing the order.
6.2 Chemical analysis
Sampling shall be carried out at the time of casting according to EN 14361. The average content accuracy to
each sample shall be within the specification for the chemical composition.
NOTE 1 EN 14361 includes criteria how to determine number, volume and shape of sample, about time and location
of sampling and about the design and maintenance of the tools, in order to make sure that the average chemical
composition of the sample is representative of the average chemical composition of the whole melt.
