This document specifies the Vickers hardness test method for the three different ranges of test force for
metallic materials, including hard metals and other cemented carbides (see Table 1), metallic coatings
and other inorganic coatings.
The Vickers hardness test is specified in this document for lengths of indentation diagonals between
0,020 mm and 1,400 mm. Using this method to determine Vickers hardness from smaller indentations
is outside the scope of this document as results would suffer from large uncertainties due to the
limitations of optical measurement and imperfections in tip geometry.
The Vickers hardness specified in this document is also applicable for metallic and other inorganic
coatings including electrodeposited coatings, autocatalytic coatings, sprayed coatings and anodic
coatings on aluminium.
This document is applicable to measurements normal to the coated surface and to measurements on
cross-sections, provided that the characteristics of the coating (smoothness, thickness, etc.) permit
accurate readings of the diagonal of the indentation.
This document is not applicable for coatings with thickness less than 0,030 mm when testing normal
to the coating surface. This standard is not applicable for coatings with thickness less than 0,100 mm
when testing a cross-section of the coating. ISO 14577-1 can be used for the determination of hardness
from smaller indentations.”
A periodic verification method is specified for routine checking of the testing machine in service by the
user.
For specific materials and/or products, relevant International Standards exist.
