Metallic materials - Vickers hardness test - Part 2: Verification and calibration of testing machines (ISO 6507-2:2018)

ISO 6507-2:2018 specifies a method of verification and calibration of testing machines and diagonal measuring system for determining Vickers hardness in accordance with ISO 6507‑1.
A direct method of verification and calibration is specified for the testing machine, indenter and the diagonal length measuring system. An indirect verification method using reference blocks is specified for the overall checking of the machine.
If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method.
ISO 6507-2:2018 is also applicable to portable hardness testing machines but not applicable to hardness testing machines based on different measurement principles, e.g. ultrasonic impedance method.

Metallische Werkstoffe - Härteprüfung nach Vickers - Teil 2: Überprüfung und Kalibrierung der Prüfmaschinen (ISO 6507-2:2018)

Dieses Dokument legt ein Verfahren für die Überprüfung und Kalibrierung von Härteprüfmaschinen und Diagonalmesssystemen zur Bestimmung der Vickers-Härte nach ISO 6507 1 fest.
Für die Überprüfung und Kalibrierung der Prüfmaschine, des Eindringkörpers und des Diagonalmesssystems wird ein direktes Verfahren festgelegt. Für die allgemeine Überprüfung der Maschine wird ein indirektes Überprüfungsverfahren unter Verwendung von Härtevergleichsplatten festgelegt.
Wird eine Prüfmaschine auch für andere Härteprüfverfahren verwendet, muss sie unabhängig für jedes Verfahren überprüft werden.
Dieses Dokument ist auch auf tragbare Härteprüfgeräte anwendbar, jedoch nicht auf Härteprüfmaschinen auf Grundlage von verschiedenen Messgrundsätzen, z. B. Ultraschall-Impedanzverfahren.

Matériaux métalliques - Essai de dureté Vickers - Partie 2: Vérification et étalonnage des machines d'essai (ISO 6507-2:2018)

L'ISO 6507-2:2018 spécifie une méthode de vérification des machines d'essai et des systèmes de mesure de diagonale utilisées pour la détermination de la dureté Vickers conformément à l'ISO 6507‑1.
Une méthode directe de vérification et d'étalonnage est spécifiée pour la machine d'essais, le pénétrateur et le système de mesure de la longueur de la diagonale. Une méthode de vérification indirecte à l'aide de blocs de référence est spécifiée pour la vérification globale de la machine.
Si une machine d'essai est également utilisée pour d'autres méthodes d'essai de dureté, elle doit être vérifiée indépendamment pour chaque méthode.
L'ISO 6507-2:2018 est également applicable aux machines d'essai de dureté portables mais n'est pas applicable aux machines d'essai de dureté basées sur des principes de mesure différents, par exemple une méthode d'impédance ultrasonore.

Kovinski materiali - Preskus trdote po Vickersu - 2. del: Preverjanje in umerjanje naprav za preskušanje (ISO 6507-2:2018)

Ta dokument določa metodo za preverjanje in umerjanje preskuševalnih naprav in sistema za merjenje diagonale za določanje trdote po Vickersu v skladu s standardom ISO 6507-1.
Določa neposredno metodo za preverjanje in umerjanje naprave za preskušanje, preskusne konice in sistema za merjenje dolžine diagonale. Za splošno pregledovanje naprave določa posredno metodo preverjanja z uporabo primerjalnih ploščic.
Če se naprava za preskušanje uporablja tudi za druge metode preskusa trdote, jo je treba preveriti posebej za vsako metodo.
Ta dokument se uporablja tudi za prenosne naprave za preskušanje trdote, vendar pa se ne uporablja za naprave za preskušanje trdote, ki temeljijo na drugih načelih merjenja, npr. na metodi ultrazvočne impedance.

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 patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals,
Subcommittee SC 3, Hardness testing.
This fourth edition cancels and replaces the third edition (ISO 6507-2:2005), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— all references of indentation diagonals, <0,020 mm, have been removed;
— requirements for the calibration and verification of the measuring system have been revised;
— requirements for the maximum permissible error in measuring a reference indentation have been
revised;
— recommendations for inspection and monitoring of the indenter have been moved to ISO 6507-1;
— requirements have been added to the test report for reporting the hardness values of reference
blocks used;
— Annex A has been revised.
A list of all parts in the ISO 6507 series can be found on the ISO website.
