Foreword
This European Standard has been prepared by Technical Committee ECISS/TC 1 "Steel - Mechanical testing", the
secretariat of which is held by AFNOR.
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by endorsement, at the latest by January 2002, and conflicting national standards shall be withdrawn at the latest
by January 2002.
This European Standard supersedes EN 10002-1:1990.
The European Standard EN 10002-1 "Metallic materials - Tensile testing - Part 1: Method of test (at ambient
temperature)" was approved by CEN on 27 November 1989.
After a first 5 years lifetime, ECISS decided to revise this standard.
The revised prEN 10002-1 was discussed during two meetings of ECISS/TC1/SC1 with the participation of 4 CEN
member countries (Belgium, France, Germany, United Kingdom).
EN 10002 was composed of five parts :
Part 1 : Method of test (at ambient temperature)
Part 2 : Verification of the force measuring system of the tensile testing machines
Part 3 : Calibration of force proving instruments used for the verification of uniaxial testing machines
Part 4 : Verification of extensometers used in uniaxial testing
Part 5 : Method of testing at elevated temperature
NOTE Part 2 has been already replaced by EN ISO 7500-1. Parts 3 and 4 will be replaced by corresponding ISO
standards.
The annexes B, C, D and E are normative. The annexes A, F, G, H and J are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the method for tensile testing of metallic materials and defines the mechanical
properties which can be determined at ambient temperature.
NOTE Informative annex A indicates complementary recommendations for computer controlled testing machines. It is the
intention, based on further developments by manufacturers and users that annex A will become normative in the next revision of
this standard.
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 (including amendments).

3 Principle
The test involves straining a test piece in tension, generally to fracture, for the purpose of determining one or more
of the mechanical properties defined in clause 4.
The test is carried out at ambient temperature between 10 °C and 35 °C, unless otherwise specified. Tests carried
out under controlled conditions shall be made at a temperature of 23 °C ± 5 °C.
4 Terms and definitions
For the purpose of this European Standard, the following terms and definitions apply :
4.1
gauge length (L)
length of the cylindrical or prismatic portion of the test piece on which elongation is measured. In particular, a
distinction is made between :
4.1.1
original gauge length (L )
o
gauge length before application of force
4.1.2
final gauge length (L )
u
gauge length after rupture of the test piece (see 11.1)
4.2
parallel length (L )
c
parallel portion of the reduced section of the test piece
NOTE The concept of parallel length is replaced by the concept of distance between grips for non-machined test pieces.
4.3
elongation
increase in the original gauge length (L ) at any moment during the test
o
4.4
percentage elongation
elongation expressed as a percentage of the original gauge length (L )
o
4.4.1
percentage permanent elongation
increase in the original gauge length of a test piece after removal of a specified stress (see 4.9), expressed as a
percentage of the original gauge length (L )
o
4.4.2
percentage elongation after fracture (A)
permanent elongation of the gauge length after fracture (L - L ), expressed as a percentage of the original gauge
u o
length (L )
o

NOTE In the case of proportional test pieces, only if the original gauge length is other than 5,65 S where S is the
o o
original cross-sectional area of the parallel length, the symbol A should be supplemented by an index indicating the coefficient
of proportionality used, for example :
A = percentage elongation of a gauge length (L ) of 11,3 S .
11,3 o o
In the case of non-proportional test pieces, the symbol A should be supplemented by an index indicating the original gauge
length used, expressed in millimetres, for example :
A = percentage elongation of a gauge length (L ) of 80 mm.
80 mm o
4.4.3
percentage total elongation at fracture (A )
t
total elongation (elastic elongation plus plastic elongation) of the gauge length at the moment of fracture expressed
as a percentage of the original gauge length (L )
o
4.4.4
percentage elongation at maximum force
increase in the gauge length of the test piece at maximum force, expressed as a percentage of the original gauge
