Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10113 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 2, Ductility testing.
This second edition cancels and replaces the first edition (ISO 10113:1991), which has been technically
revised.
This corrected version of ISO 10113:2006 incorporates the following corrections.
⎯ In 3.1, the definition has been updated and previous Note 4 has been incorporated into Note 2.
1)
⎯ In 3.2 and 3.3, second indexes for the strain level have been added. The previous footnote has been
inserted as Note 2.
⎯ In Table 1, corrections to the symbols and designations have been made for specified plastic strain,
specified plastic strain range, plastic strain ratio, weighted average of r values and the slope of the
x/y
elastic part of the stress/percentage extension curve.
⎯ In 9.2, the word “a” has been deleted in the second line between “For” and “better”.
⎯ Symbol corrections have been made in Equation (5) and Equation (7).
⎯ Figures 1 and 2 and the associated keys have been modified.

INTERNATIONAL STANDARD ISO 10113:2006(E)
Metallic materials — Sheet and strip — Determination of plastic
strain ratio
1 Scope
This International Standard specifies a method for determining the plastic strain ratio of flat products (sheet
and strip) made of metallic materials.
2 Normative references
The following referenced documents are indispensable for the application 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.
ISO 6892:1998, Metallic materials — Tensile testing at ambient temperature
ISO 9513:1999, Metallic materials — Calibration of extensometers used in uniaxial testing
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
plastic strain ratio
r
ratio of the true plastic width strain to the true plastic thickness strain in a test piece that has been subjected to
uniaxial tensile stress
ε
b
r = (1)
ε
a
where
ε is the true plastic thickness strain;
a
ε is the true plastic width strain.
b
NOTE 1 The above expression using a single point is only valid in the region where the plastic strain is homogeneous.
NOTE 2 Since it is easier and more precise to measure changes in length than in thickness, the following relationship
derived from the law of constancy of volume is used up to the percentage plastic extension at maximum force, A , to
g
calculate the plastic strain ratio, r.
For some materials exhibiting a phase change during plastic deformation, the volume of the measured section cannot
always be assumed to be constant. In such cases, the procedure should be defined and agreed between the parties
involved.

NOTE 3 Because the value r depends on the orientation of the test piece relative to the rolling direction, as well as on
the strain level, the symbol r may be supplemented by the angle which characterises this orientation and the strain level.
For example r (see Table 1).

3.2
weighted average plastic strain ratio
r
weighted average of the r values for different test piece orientations as calculated using the equation
x/y
rr++ 2r
0/20 90/20 45/20
r = (3)
NOTE 1 If r is determined, all tests should be performed at the same strain/strain range.
NOTE 2 For some materials, other test piece orientations may be chosen, in which case equations other than
Equation (3) should be used.
3.3
degree of planar anisotropy
∆r
value calculated using the following equation
(2rr+−r)
0/20 90/20 45/20
∆r = (4)
NOTE 1 If ∆r is determined, all tests should be performed at the same strain/strain range.
NOTE 2 For some materials, other test piece orientations may be chosen, in which case equations other than
Equation (4) should be used.
