This document specifies the Vickers hardness test method for the three different ranges of test force for
metallic materials including hardmetals and other cemented carbides (see Table 1).
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.
A periodic verification method is specified for routine checking of the testing machine in service by
the user.
For specific materials and/or products, particular International Standards exist.

ISO 6507-1:2018 specifies the Vickers hardness test method for the three different ranges of test force for metallic materials including hardmetals and other cemented carbides.

NOTE   In the case of a harmonised supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.

This European Standard specifies a procedure on how to improve the performance of a routine XRF method, already in use for analysis of high alloy steels, by using a ”near by technique”.
The ”near by technique” requires at least one target sample (preferable a CRM) of a similar composition as the unknown sample.
The method is applicable to elements within the concentration ranges according to Table 1:
Table 1 — Concentration ranges
Element   Concentration range, % (m/m) a
Si   0,05 to 1,5
Mn   0,05 to 5,0
P   0,005 to 0,035
Cr   10 to 25
Ni   0,1 to 30
Mo   0,1 to 6,5
Cu   0,02 to 1,5
Co   0,015 to 0,30
V   0,015 to 0,15
Ti   0,015 to 0,50
Nb   0,05 to 1,0
a   The concentration ranges specified, represents those ranges studied during the precision test. The procedure has the potential to be used outside those ranges but it needs to be validated by each laboratory in every case.
The method is applicable to analysis of either chill-cast or wrought samples having a diameter of at least 25 mm and with a carbon concentration of less than 0,3 % (see NOTE). Other elements should have a concentration below 0,2 %.
NOTE   High carbon concentrations, in combination with high Mo and Cr concentrations, could have undesirable structural effects on the sample and could affect the determination of phosphorus and chromium, in particular.
Matrix effects exist between the elements listed. To compensate for those inter-element effects, mathematical corrections shall be applied. A variety of computer programs for corrections is commonly used and included in the software package from the manufacturers.
