This European Standard shall be given the status of a

national standard, either by publication of an identical

text or by endorsement, at the latest by March 1997,

and conflicting national standards shall be withdrawn

at the latest by March 1997

Within its programme of work, Technical Committee

CEN/TC 132 entrusted CEN/TC 132/WG 3, Forgings and

cast and wrought forging stock, to prepare the

following standard:

EN 603-2 Aluminium and aluminium alloys Ð

Wrought forging stock

Part 2: Mechanical properties

This standard is part of a set of three standards The

other standards deal with:

Part 1: Technical conditions for inspection

and delivery

Part 3: Tolerances on dimensions and

form

According to the CEN/CENELEC Internal Regulations,

the national standards bodies of the following

countries are bound to implement this European

Standard: Austria, Belgium, Denmark, Finland, France,

Germany, Iceland, Italy, Luxembourg, Netherlands,

Norway, Portugal, Spain, Sweden, and the United

Kingdom

1 Scope

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

2 Normative references

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

Chemical composition and form of

wrought products

Part 3: Chemical composition

Part 1: Technical conditions for

temperature)

3 Definitions

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.

4 Tensile testing

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

5 Mechanical properties

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

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

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 0,2does not exceed minimum

specified in the standard by more than 85 MPa

acceptable

22,0 # g < 23,2 per specified requirements but Rp 0,2exceeds minimum specified

in the standard by more than 85 MPa

suspect (see note)

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
