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.
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.
International Standard ISO 6507-1 was prepared by Technical Committee ISO/TC 164, Mechanical testing
of metals, Subcommittee SC 3, Hardness testing.
This second edition of ISO 6507-1 cancels and replaces ISO 6507-1:1982, ISO 6507-2:1983,
ISO 6507-3:1989, ISO 409-1:1982, ISO 409-2:1983 and ISO/DIS 409-3:1992 as follows:
— Combination of the three different International Standards for the ranges of the test force
(ISO 6507-1:1982, ISO 6507-2:1983, ISO 6507-3:1989) into this part of ISO 6507.
— Integration of the tables for the calculation of Vickers hardness values for uses in tests made
on flat surfaces (ISO 409-1:1982, ISO 409-2:1983 and ISO/DIS 409-3:1992) as annex C of this part of
ISO 6507.
— The test method is specified for lengths of indentation diagonals between 0,020 mm and 1,400 mm.
— If the difference between the lengths of the two indentation diagonals is greater than 5 %, this is
stated in the test report.
— Addition of a new clause 8 concerning the uncertainty of the test results.
— Addition of a new informative annex D "Monitoring the uncertainty of the hardness testing
machines by the users".
ISO 6507 consists of the following parts, under the general title Metallic materials — Vickers hardness
test:
— Part 1: Test method
— Part 2: Verification of testing machines
— Part 3: Calibration of reference blocks
Annexes A, B and C form an integral part of this part of ISO 6507. Annexes D and E are for information
only.

INTERNATIONAL STANDARD ISO ISO 6507-1:1997(E)
Metallic materials — Vickers hardness test —
Part 1:
Test method
1 Scope
This part of ISO 6507 specifies the method of Vickers hardness test for the three different ranges of
test force for metallic materials (see table 1).
Table 1
Ranges of test force, F Hardness symbol Previous designation
N (ISO 6507-1:1982)
F > 49,03 > HV 5 Vickers hardness test
1,961 < F , 49,03 HV 0,2 to < HV 5 Low load Vickers hardness test
0,098 07 < F , 1,961 HV 0,01 to < HV 0,2 Vickers microhardness test
The Vickers hardness test is specified in this part of ISO 6507 for lengths of indentation diagonals
between 0,020 mm and 1,400 mm.
The force values in this part of ISO 6507 were calculated from kilogram force values. They were
introduced before the SI-system was adopted. It was decided to keep the values based on the old
units for this edition, but for the next revision it will be necessary to consider the advantage of
introducing rounded values of test force and the consequence on the hardness scales.
NOTE — In general, decreasing the test force increases the scatter of results of the measurements. This is
particularly true for low-force Vickers hardness tests and Vickers microhardness tests where the principal
limitation will arise in the measurement of the diagonals of the indentation. For Vickers microhardness, the
accuracy of determination of the mean diagonal length is unlikely to be better than ± 0,001 mm (see annex E).
For specific materials and/or products, particular International Standards exist.
2 Normative reference
The following standard contains provisions which, through reference in this text, constitute
provisions of this part of ISO 6507. At the time of publication, the edition indicated was valid. All
standards are subject to revision, and parties to agreements based on this part of ISO 6507 are
encouraged to investigate the possibility of applying the most recent edition of the standard indicated
below. Members of IEC and ISO maintain registers of currently valid International Standards.

3 Principle
A diamond indenter in the form of a right pyramid with a square base and with a specified angle
between opposite faces at the vertex is forced into the surface of a test piece followed by
measurement of the diagonal length of the indentation left in the surface after removal of the test
force, F (see figure 1).
Figure 1 — Principle of the test
The Vickers hardness is proportional to the quotient obtained by dividing the test force by the sloping
area of the indentation which is assumed to be a right pyramid with a square base, and having at the
vertex the same angle as the indenter.

6 Test piece
6.1 The test shall be carried out on a surface which is smooth and even, free from oxide scale,
foreign matter and, in particular, completely free from lubricants, unless otherwise specified in
product standards. The finish of the surface shall permit accurate determination of the diagonal
length of the indentation.
6.2 Preparation shall be carried out in such a way that any alteration of the surface hardness, due to
heat or cold-working, for example, is minimized.
Due to the small depth of Vickers microhardness indentations, it is essential that special precautions
are taken during preparation. It is recommended to use a polishing/electropolishing process which is
suitable for the material parameters.
6.3 The thickness of the test piece or of the layer under test shall be at least 1,5 times the diagonal
length of the indentation (see annex A).
No deformation shall be visible at the back of the test piece after the test.
6.4 For tests on curved surfaces, the corrections given in annex B, tables B.1 to B.6 shall be applied.
6.5 For test pieces of small cross-section or of irregular shape, it may be necessary to provide some
form of additional support.
7 Procedure
7.1 In general, the test is carried out at ambient temperature within the limits of 10 °C to 35 °C.
Tests carried out under controlled conditions shall be made at a temperature of (23 ± 5) °C.
7.2 The following test forces (see table 3) shall be used.

7.3 The test piece shall be placed on a rigid support. The support surfaces shall be clean and free
from foreign matter (scale, oil, dirt, etc.). It is important that the test piece lies firmly on the support so
that displacement cannot occur during the test.
7.4 Bring the indenter into contact with the test surface and apply the test force in a direction
perpendicular to the surface, without shock or vibration, until the applied force attains the specified
value. The time from the initial application of the force until the full test force is reached shall not be
less than 2 s nor greater than 8 s. For low-force hardness and microhardness tests, this time shall not
exceed 10 s. For low-force hardness and microhardness tests, the approach speed of the indenter
shall not exceed 0,2 mm/s.
The duration of the test force shall be 10 s to 15 s.
For particular materials, a longer time for maintaining the force is provided; this time shall be applied
with a tolerance of ± 2 s.
7.5 Throughout the test, the testing machine shall be protected from shock or vibration.
7.6 The distance between the centre of any indentation and the edge of the test piece shall be at least
2,5 times the mean diagonal length of the indentation in the case of steel, copper and copper alloys
and at least three times the mean diagonal length of the indentation in the case of light metals, lead
and tin and their alloys.
The distance between the centres of two adjacent indentations shall be at least three times the mean
diagonal length of the indentation in the case of steel, copper and copper alloys, and at least six times
the mean diagonal length in the case of light metals, lead and tin and their alloys. If two adjacent
indentations differ in size, the spacing shall be based on the mean diagonal length of the larger
indentation.
7.7 Measure the lengths of the two diagonals. The arithmetical mean of the two readings shall be
taken for the calculation of the Vickers hardness.
For flat surfaces, the difference between the lengths of two indentation diagonals should not be
greater than 5 %. If the difference is greater, this shall be stated in the test report.
8 Uncertainty of the results
The uncertainty of results is dependent on various parameters which may be separated into two
categories:
a) parameters depending on the Vickers hardness testing machine (including the uncertainty of
the verification of the testing machine and of the calibration of the reference blocks);
b) parameters depending on the application of the test method (variation of the operating
conditions).
NOTE — In the absence of sufficient data on those parameters it is not possible, at present, to fix values of
accuracy, but the uncertainty may approach approximately ± 10 % of the measured hardness values.

9 Test report
The test report shall include the following information:
a) reference to this part of ISO 6507;
b) all details necessary for identification of the test piece;
c) the result obtained;
d) all operations not specified by this part of ISO 6507, or regarded as optional;
e) details of any occurrence which may have affected the results;
f) the temperature of the test, if it is outside the range specified in 7.1.
NOTES
1 A strict comparison of hardness values is only possible at identical test forces.
2 There is no general process of accurately converting Vickers hardness into other scales of hardness or into
tensile strength. Such conversions therefore should be avoided, unless a reliable basis for conversion can be
obtained by comparison tests.
3 It should be noted that for anisotropic materials, for example those which have been heavily cold-worked,
there will be a difference between the lengths of the two diagonals of the indentation. Where possible, the
indentation should be made so that the diagonals are inclined at approximately 45° to the direction of
cold-working. The specification for the product may indicate limits for the differences between the lengths of the
two diagonals.
4 There is evidence that some materials may be sensitive to the rate of straining which causes small changes in
the value of the yield stress. The corresponding effect on the termination of the formation of an indentation can
make alterations in the hardness value.
