European foreword
This document (prEN 2002-002:2024) 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 EN 2002-002:2005.

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 elevated
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.

3.1
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 original gauge length of L = 5,65 S

Note 1 to entry: A non-standard proportional test piece is one in which the proportionality coefficient has a value
other than 5,65. In the example above the gauge length is four times the diameter, equivalent to a proportionality
coefficient of 4,51.
Note 2 to entry: The unit is %.
3.9

thickness of a test piece of rectangular cross-section or wall thickness of a tube
Note 1 to entry: The unit is mm.
