1 Scope
4 Tensile testing
This Part of EN 603 specifies the mechanical properties
of wrought forging stock in aluminium and aluminium
alloys for general engineering applications.
The chemical composition and temper designations for
these alloys are specified in EN 573-3 and
EN 515 respectively.
For the selection of specimens and preparation of test
pieces, see EN 603-1.
Tensile testing shall be carried out in accordance with
EN 10002-1.
2 Normative references
5.1 Extruded forging stock
Extruded forging stock is normally supplied in the F or
H112 temper condition.
Testing to determine mechanical properties of extruded
forging stock shall be undertaken only when requested
by the purchaser and specified on the order (see
EN 603-1).
In instances where tensile testing is specified on
extruded forging stock in heat treatable alloys, the
specimen selected for test shall be heat treated in
accordance with the recommended practice for the
temper condition of final use.
The mechanical properties of aluminium alloys are
specified in tables 1 to 6.
Test results shall be rounded in accordance with the
rules given in annex A.
For section sizes greater than those quoted, the levels
of mechanical properties shall be as agreed between
purchaser and supplier.
This European Standard incorporates by dated or
undated reference, provisions from other publications.
These normative references are cited at the
appropriate places in the text and the publications are
listed hereafter. For dated references, subsequent
amendments to or revisions of any of these
publications apply to this European standard only
when incorporated in it by amendment or revision. For
undated references the latest edition of the publication
referred to applies.

For the purposes of this standard the following
definition applies:
3.1 section size
The minor sectional dimension, i.e. diameter for
extruded round bar, width across flats for extruded
square bar and thickness for extruded rectangular
section, designated t.
BSI 1997
5 Mechanical properties
5.2 Rolled forging stock
Mechanical properties for rolled forging stock shall be
subject to agreement between purchaser and supplier.
6 Electrical conductivity
The electrical conductivity of extruded forging stock
produced in alloy EN AW-7075 in the T732 temper
condition shall be determined in accordance with
EN 2004-1, as part of the inspection lot acceptance, by
testing the surface of the previously selected tensile
test specimen to the criteria shown in table 6.

1) For inspection lot acceptance purposes, extruded forging stock in T732 temper shall comply with the following criteria when
tested on the previously selected tensile test specimen.
Electrical conductivity (g)
MS/m
Level of mechanical properties
Lot acceptance status
g $ 23,2
per specified requirements
acceptable
22,0 # g <23,2
per specified requirements and Rp 0,2 does not exceed minimum
specified in the standard by more than 85 MPa
acceptable
22,0 # g < 23,2
per specified requirements but Rp 0,2 exceeds minimum specified
in the standard by more than 85 MPa
suspect (see note)
g < 22,0
any level
unacceptable
NOTE. When the lot acceptance status is found to be suspect, the specimen shall be reprocessed or subjected to a heat
treatment for not less than 30 min at (465 ± 5) ÊC and quenched into cold water. Electrical conductivity shall then be measured
within 15 min of quenching. If the difference between this measurement and the original measurement on the specimen
is 3,5 MS/m or more, the inspection lot is acceptable. If the difference is less than 3,5 MS/m the inspection lot is unacceptable.

Annex A (normative)
Rules for rounding
In recording test results, the number representing the
result of a test to determine a given property shall be
expressed to the same number of decimal places as
the corresponding number in this European Standard.
The following rounding rules shall be used for
determination of compliance with this standard:
a) When the figure immediately after the last figure
to be retained is less than 5, the last figure to be
retained remains unchanged;
b) When the figure immediately after the last figure
to be retained is greater than 5, or equal to 5 and
followed by at least one figure other than zero, the
last figure to be retained is increased by one;
c) When the figure immediately after the last figure
to be retained is equal to 5 and followed by zeros
only, the last figure to be retained remains
unchanged if even and is increased by one if odd.
