Metallic materials - Rockwell hardness test - Part 2: Verification and calibration of testing machines and indenters (ISO 6508-2:2023)

This document specifies two separate methods of verification of testing machines (direct and indirect) for determining Rockwell hardness in accordance with ISO 6508-1, together with a method for verifying Rockwell hardness indenters.
The direct verification method is used to determine whether the main parameters associated with the machine function, such as applied force, depth measurement, and testing cycle timing, fall within specified tolerances. The indirect verification method uses a number of calibrated reference hardness blocks to determine how well the machine can measure a material of known hardness.
This document is applicable to stationary and portable hardness testing machines.
Attention is drawn to the fact that the use of tungsten carbide composite for ball indenters is considered to be the standard type of Rockwell indenter ball.

Metallische Werkstoffe - Härteprüfung nach Rockwell - Teil 2: Überprüfung und Kalibrierung der Prüfmaschinen und Eindringkörper (ISO 6508-2:2023)

Dieses Dokument legt zwei unterschiedliche Verfahren für die Überprüfung von Härteprüfmaschinen (direkt und indirekt) zur Bestimmung der Rockwellhärte nach ISO 6508 1 in Verbindung mit einem Verfahren für die Überprüfung von Rockwell-Härteeindringkörpern fest.
Die direkte Überprüfung wird angewendet, um festzustellen, ob die Hauptparameter der Maschinenfunktion, wie z. B. die aufgebrachte Kraft, die Eindringtiefenmessung und die zeitliche Steuerung der Prüfzyklen, die festgelegten Grenzabweichungen einhalten. Bei der indirekten Überprüfung wird eine Reihe von kalibrierten Härtevergleichsplatten verwendet, um festzustellen, wie gut die Prüfmaschine, einen Werkstoff bekannter Härte messen kann.
Dieses Dokument ist auf ortsfeste und tragbare Härteprüfmaschinen anwendbar.
Es ist zu beachten, dass als Normeindringkugel für die Rockwell-Prüfung nur solche aus Wolframcarbidgemisch gelten.

Matériaux métalliques - Essai de dureté Rockwell - Partie 2: Vérification et étalonnage des machines d'essai et des pénétrateurs (ISO 6508-2:2023)

Le présent document spécifie deux méthodes séparées de vérification des machines d'essai (directe et indirecte) pour la détermination de la dureté Rockwell selon l’ISO 6508-1, de même qu’une méthode de vérification des pénétrateurs de dureté Rockwell.
La méthode de vérification directe est utilisée pour déterminer si les principaux paramètres associés aux fonctions de la machine, telles que la force appliquée, le mesurage de l’enfoncement et le phasage du cycle d’essai, se situent dans les tolérances spécifiées. La méthode de vérification indirecte utilise un certain nombre de blocs de dureté de référence étalonnés pour déterminer avec quelle exactitude la machine peut mesurer un matériau de dureté connue.
Le présent document est applicable aux machines d'essai de dureté fixes et portables.
L’attention est attirée sur le fait que l’utilisation d’un composite en carbure de tungstène pour les pénétrateurs à bille est considérée être le type courant de bille de pénétrateur Rockwell.

Kovinski materiali - Preskus trdote po Rockwellu - 2. del: Preverjanje in umerjanje naprav za preskušanje (ISO 6508-2:2023)

Ta dokument določa dve ločeni metodi za preverjanje naprav za preskušanje (neposredna in posredna)
za določanje trdote po Rockwellu v skladu s standardom ISO 6508-1 skupaj z metodo za preverjanje
vtisnih teles za preskušanje trdote po Rockwellu.
Metoda neposrednega preverjanja se uporablja za določanje, ali so glavni parametri, povezani z
delovanjem stroja, npr. uporabljena sila, merjenje globine in čas preskusnega cikla, znotraj
dovoljenih toleranc. Pri posredni metodi preverjanja se uporabi določeno število
umerjenih ploščic referenčne trdote, s katerimi se preveri, kako natančno lahko naprava izmeri material z znano trdoto.
Ta dokument se uporablja za nepremične in premične naprave za preskušanje trdote.
Opozoriti je treba, da se za standardno vrsto vtisne krogle po Rockwellu šteje kroglično vtisno telo
iz kompozita volframovega karbida.
