This document (prEN 2002-001:2024) has been prepared by ASD-STAN.
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede prEN 2002-001:2019.
The main changes with respect to the previous edition are as follows:
— prEN 2002-001 (P5), 03/2019:
o overall editorial improvements;
o subclause 6.3.6.2:
• 0,003 to 0,007 (0,3 % to 0,7 %) per min., a strain rate of 0,005 (0,5 %) per min is preferred;
• changed to: “The test shall be performed at a strain rate as required in Table 2 and
Table 3”.
The strain-rate, mentioned in 6.3.6.2, of 0,003/min to 0,007/min is too low. ASTM B557 and
EN 485-2 work with a rate of stress application of maximum 12 MPa/s. For aluminium with an
E-Modulus of about 72 000 MPa this results to a strain-rate of 0,01/min. All testing machines
work with a stressing rate in this range of 12 MPa/s. So consequently, beginning with leaving
the Hooke's line (linear relationship between stress and strain) up to achieving the yield
strength R significant higher strainrates of 0,04/min to 0,05/min at simultaneously
p0,2
significant decreasing stressing rates are determined;
o subclause 6.3.6.3: if the test is to be continued to fracture, the strain rate of the parallel length
may be increased beyond the proof stress but shall not exceed a value of 0,1 (10 %) per min.
Changed to: “If the test is to be continued to fracture, the strain rate of the parallel length may
be increased beyond the proof stress but shall not exceed a value required in Table 2 and
Table 3”.
The strain-rate, mentioned in 6.3.6.3, of 0,1 (10 %)/min is significantly too low. All other
relevant specifications (ASTM B557, EN 485-2 and EN 10002-1:2001) allow a strain rate up to
0,5 (50 %)/min. That means conversely, one tensile test would take five times longer by
application of EN 2002-001. The throughput of one test-machine would decrease to 1/5;
o subclauses 6.3.6.2 and 6.3.6.3: Table 2 with required test speeds implemented for the following
both groups: aluminium and aluminium alloys; engineering steels and stainless steels; all other
metallic materials.
Introduction
This document is part of the series of EN metallic material standards for aerospace applications.
The general organization of this series is described in EN 4258.
1 Scope
This document specifies the requirements for the tensile testing of metallic materials at ambient
temperature for aerospace applications.
It is applied when referred to in the EN technical specification or material standard unless otherwise
specified on the drawing, order or inspection schedule.

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 4259 and the following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:

3.1
test piece
portion of the test sample on which the tensile test is carried out
3.2
proportional test piece
test piece with an original gauge length (L ) having a specified relationship to the square root of the
cross-sectional area (S )
Note 1 to entry: The proportionality coefficient, K, has the internationally recognized value of 5,65 for test pieces
of circular cross-section. The gauge length of a proportional test piece is therefore equal to 5,65√(S_0). Certain
material standards use proportional test pieces with other than the 5,65 proportionality coefficient. In this case,
see A for the percentage elongation symbol used.
x
3.3
non-proportional test piece
test piece where the original gauge length is independent of the cross-sectional area
3.4
extension
increase of the extensometer gauge length (L ) at any moment during the test
e
Note 1 to entry: The unit is mm.
3.5
limit of proportionality
stress at which the stress-strain (or force-extension) relationship deviates from a straight line
Note 1 to entry: The unit is MPa.
3.6
percentage elongation
A
elongation after fracture expressed as a percentage of the original gauge
length (L ) for a proportional test piece with an origin
