1 This test method is under the jurisdiction of ASTM Committee E04 on
Metallography and is the direct responsibility of Subcommittee E04.05 on Microindentation
Hardness Testing.With this revision the test method was expanded to
include the requirements previously defined in E28.92, Standard Test Method for
Vickers Hardness Testing of Metallic Material that was under the jurisdiction of
E28.06

1. Scope
1.1 This test method covers determination of the Knoop and
Vickers hardness of materials, the verification of Knoop and
Vickers hardness testing machines, and the calibration of
standardized Knoop and Vickers test blocks.
1.2 This test method covers Knoop and Vickers hardness
tests made utilizing test forces in micro (9.807 3 10-3 to 9.807
N ) ( 1 to 1000 gf ) and macro (>9.807 to 1176.80 N) ( >1kg
to 120 kgf ) ranges.
NOTE 1—Previous versions of this standard limited test forces to 9.807
N (1 kgf).
1.3 This test method includes all of the requirements to
perform macro Vickers hardness tests as previously defined in
Test Method E92, Standard Test Method for Vickers Hardness
Testing.
1.4 This test method includes an analysis of the possible
sources of errors that can occur during Knoop and Vickers
testing and how these factors affect the accuracy, repeatability,
and reproducibility of test results.
NOTE 2—While Committee E04 is primarily concerned with metals, the
test procedures described are applicable to other materials.
1.5 Units—When Knoop and Vickers hardness tests were
developed, the force levels were specified in units of gramsforce
(gf) and kilograms-force (kgf). This standard specifies
the units of force and length in the International System of
Units (SI); that is, force in Newtons (N) and length in mm or
μm. However, because of the historical precedent and continued
common usage, force values in gf and kgf units are
provided for information and much of the discussion in this
standard as well as the method of reporting the test results
refers to these units.
1.6 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
