Metallic materials - Instrumented indentation test for hardness and materials parameters - Part 2: Verification and calibration of testing machines (ISO/DIS 14577-2:2024)

ISO 14577-2:2015 specifies the method of verification and calibration of testing machines for carrying out the instrumented indentation test in accordance with ISO 14577‑1:2015.
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.
ISO 14577-2:2015 is also applicable for transportable testing machines.

Matériaux métalliques - Essai de pénétration instrumenté pour la détermination de la dureté et de paramètres des matériaux - Partie 2: Vérification et étalonnage des machines d'essai (ISO/DIS 14577-2:2024)

L'ISO 14577-2:2015 spécifie la méthode de vérification et d'étalonnage des machines d'essai destinées à la réalisation de l'essai de pénétration instrumenté conformément à l'ISO 14577‑1:2015.
Elle décrit une méthode de vérification directe pour contrôler les fonctions principales de la machine d'essai et une méthode de vérification indirecte appropriée pour la détermination de la répétabilité de la machine d'essai. Il est exigé que la méthode indirecte soit utilisée en sus de la méthode directe et pour le contrôle de routine périodique de la machine d'essai en service.
Il est exigé que la méthode indirecte de vérification de la machine d'essai soit réalisée de façon indépendante pour chaque méthode d'essai.
L'ISO 14577-2:2015 est également applicable aux machines d'essai transportables.

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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
