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.
