---------------------- Page: 7 ----------------------
EN 485-1:2008 (E)
The order document should indicate the intended application.
NOTE 2 The codification scheme specified in EN 573-5 should be used.
5 Requirements
5.1 Responsibilities of the supplier and manufacturer
The supplier shall be responsible that all inspections and tests required by the relevant standard and/or the
particular specification have been performed, prior to shipment of the product.
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 Requirements on product properties
5.2.1 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.
5.2.2 Mechanical properties
The mechanical properties determined by the tensile test shall be in conformity with those specified in prEN 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.
5.2.3 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 evidence of exfoliation corrosion when subjected to ASTM G66
accelerated exfoliation corrosion susceptibility test and/or Intergranular corrosion susceptibility according to
ASTM G67.
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.
5.2.4 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.
7
---------------------- Page: 8 ----------------------
EN 485-1:2008 (E)
For products intended for decorative anodizing, the superficial imperfections (discolouration, mechanical or
structural imperfections) may not be so extensive as to impair the decorative appearance after the agreed surface
treatment. Limiting samples can be agreed between supplier and purchaser.
5.2.5 Tolerances on dimensions and form
The dimensions and form tolerances shall be in conformity with the following European Standards:
EN 485-3, for hot-rolled sheet, strip and plate;
EN 485-4, for cold-rolled sheet, strip and plate;
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.
6 Test methods
6.1 General
If the purchaser wishes to inspect the product at the supplier's works, he 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.
The range of application and accuracy of the test procedure used shall be validated and proved by the supplier.
In case of dispute concerning the chemical composition, referee analysis shall be carried out in accordance with
EN 14242.
NOTE 2 For the fast determination of the chemical composition different spectral analysis methods are used (e.g. S-OES,
XRF, GDOES). For S-OES see EN 14726.
6.3 Tensile test
6.3.1 General
The tensile test shall be carried out in accordance with EN 10002-1.
Specimens shall be taken from the sample after completion of all the mechanical and thermal treatments that the
product has to undergo prior to delivery, and which can influence the mechanical properties of the metal. In cases
where this is not possible, the specimens may be taken at an earlier stage, but they shall be subjected to the same
treatment as that to which it is intended to submit the product concerned.
Cutting shall be carried out in such a manner that it does not change the characteristics of the part of the specimen
from which the test pieces are to be prepared. Thus, the dimensions of the specimens shall provide an adequate
machining allowance to permit removal at the zone affected by cutt
...
