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 Electrotech

Metallic materials - Brinell hardness test - Part 2: Verification and calibration of testing machines (ISO 6506-2:2017)
EN ISO 6506-2:2018

This document specifies methods of direct and indirect verification of testing machines used for
determining Brinell hardness in accordance with ISO 6506-1 and also specifies when these two types of
verification have to be performed.
The direct verification involves checking that individual machine performance parameters fall within
specified limits whereas the indirect verification utilizes hardness measurements of reference blocks,
calibrated in accordance with ISO 6506-3, to check the machine’s overall performance.
If a testing machine is also to be used for other methods of hardness testing, it has to be verified
independently for each method.
This document is applicable to both fixed location and portable hardness testing machines. For
machines that are incapable of satisfying the specified force-time profile, the direct verification of force
and testing cycle can be modified by the use of Annex B.

SIST EN ISO 14577-1:2015(Main)
Metallic materials - Instrumented indentation test for hardness and materials parameters - Part 1: Test method (ISO 14577-1:2015)
EN ISO 14577-1:2015

This part of ISO 14577 specifies the method of instrumented indentation test for determination of
hardness and other materials parameters for the following three ranges:
— macro range: 2 N ≤ F ≤ 30 kN;
— micro range: 2 N > F; h > 0,2 μm;
— nano range: h ≤ 0,2 μm.
For the nano range, the mechanical deformation strongly depends on the real shape of indenter tip and the
calculated material parameters are significantly influenced by the contact area function of the indenter
used in the testing machine. Therefore, careful calibration of both instrument and indenter shape is
required in order to achieve an acceptable reproducibility of the materials parameters determined with
different machines.
The macro and micro ranges are distinguished by the test forces in relation to the indentation depth.
Attention is drawn to the fact that the micro range has an upper limit given by the test force (2 N) and a
lower limit given by the indentation depth of 0,2 μm.
The determination of hardness and other material parameters is given in Annex A.
At high contact pressures, damage to the indenter is possible. For this reason in the macro range,
hardmetal indenters are often used. For test pieces with very high hardness and modulus of elasticity,
permanent indenter deformation can occur and can be detected using suitable reference materials. It is
necessary that its influence on the test result be taken into account.
This test method can also be applied to thin metallic and non-metallic coatings and non-metallic
materials. In this case, it is recommended that the specifications in the relevant standards be taken into
account (see also 6.3 and ISO 14577-4).

This part of ISO 14577 specifies the method of verification and calibration of testing machines for

It describes a direct verification method for checking the main functions of the testing machine and an
indirect verification method suitable for the determination of the repeatability of the testing machine.
There is a requirement that the indirect method be used in addition to the direct method and for the
periodic routine checking of the testing machine in service.
It is a requirement that the indirect method of verification of the testing machine be carried out
independently for each test method.
This part of ISO 14577 is also applicable for transportable testing machines.
