Metallic materials - Rockwell hardness test - Part 2: Verification and calibration of testing machines and indenters (ISO 6508-2:2015)
This part of ISO 6508 specifies two separate methods of verification of testing machines (direct and indirect) for determining Rockwell hardness in accordance with ISO 6508-1:2015, 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.
The indirect method may be used on its own for periodic routine checking of the machine in service. If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method.
This part of ISO 6508 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. Steel indenter balls may continue to be used only when complying with ISO 6508-1:2015, Annex A.
Metallische Werkstoffe - Härteprüfung nach Rockwell - Teil 2: Prüfung und Kalibrierung der Prüfmaschinen und Eindringkörper (ISO 6508-2:2015)
In diesem Teil von ISO 6508 sind 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 festgelegt.
Die direkte Überprüfung wird angewendet, um festzustellen, ob die Hauptparameter der Maschinenfunktion, wie z. B. die aufgebrachte Kraft, Eindringtiefenmessung und 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 in der Lage ist einen Werkstoff bekannter Härte zu messen..
Das indirekte Verfahren kann für sich allein zur regelmäßigen Routineüberprüfung der Maschine beim Anwender angewendet werden.
Soll eine Härteprüfmaschine auch für andere Härteprüfverfahren verwendet werden, so muss sie unabhängig für jedes dieser Verfahren überprüft werden.
Dieser Teil von ISO 6508 ist auf ortsfeste und tragbare Härteprüfmaschinen anwendbar.
Es ist zu beachten, dass als Normeindringkugel für die Rockwell-Prüfung nur solche aus Wolframcarbid-Hart-metall gelten. Stahleindringkugeln dürfen nur dann noch verwendet werden, wenn sie ISO 6508 1: , Anhang A entsprechen.
Matériaux métalliques - Essai de dureté Rockwell - Partie 2: Vérification et étalonnage des machines d'essai (ISO 6508-2:2015)
L'ISO 6508-2:2015 spécifie deux méthodes séparées de vérification des machines d'essai (directe et indirecte) pour la détermination de la dureté Rockwell conformément à l'ISO 6508‑1:2015, 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.
La méthode indirecte peut être utilisée seule pour une vérification périodique de routine de la machine en service.
Si une machine d'essai est également à utiliser pour d'autres méthodes d'essai de dureté, elle doit être vérifiée indépendamment pour chaque méthode.
L'ISO 6508-2:2015 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. Des billes de pénétrateur en acier peuvent continuer d'être utilisées seulement lorsqu'elles sont conformes à l'Annexe A de l'ISO 6508‑1:2015.
Kovinski materiali - Preskus trdote po Rockwellu - 2. del: Preverjanje in umerjanje naprav za preskušanje (ISO 6508-2:2015)
Ta del standarda ISO 6508 določa dve metodi preverjanja naprav za preskušanje (neposredno in posredno) za določanje trdote po Rockwellu v skladu s standardom ISO 6508-1:2015, skupaj z metodo za preverjanje vtisnih teles za preskušanje trdote po Rockwellu.
Z neposredno metodo preverjanja se ugotavlja, ali so glavni parametri, povezani z delovanjem naprave, kot so uporabljena sila, meritev globine in čas preskusnega ciklusa, znotraj določenih 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.
Posredni način se lahko uporabi samostojno pri rednem preverjanju naprave med delovanjem. Če se naprava za preskušanje uporablja tudi za druge metode preskusa trdote, jo je treba preveriti posebej za vsako metodo.
Ta del standarda ISO 6508 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. Jeklene vtisne krogle se lahko še naprej uporabljajo pod pogojem, da so skladne z dodatkom A k standardu ISO 6508-1:2015.
