Metallic materials - Knoop hardness test - Part 1: Test method (ISO 4545-1:2017)
ISO 4545-1:2017 specifies the Knoop hardness test method for metallic materials for test forces from 0,009 807 N to 19,613 N.
The Knoop hardness test is specified in this document for lengths of indentation diagonals ≥0,020 mm. Using this method to determine Knoop hardness from smaller indentations is outside the scope of this document as results would suffer from large uncertainties due to the limitations of optical measurement and imperfections in tip geometry. ISO 14577-1 allows the determination of hardness from smaller indentations.
A periodic verification method is specified for routine checking of the testing machine in service by the user.
Special considerations for Knoop testing of metallic coatings can be found in ISO 4516.
Metallische Werkstoffe - Härteprüfung nach Knoop - Teil 1: Prüfverfahren (ISO 4545-1:2017)
Dieses Dokument legt das Verfahren für die Härteprüfung nach Knoop an metallischen Werkstoffen für Prüfkräfte von 0,009 807 N bis 19,613 N fest.
In diesem Dokument ist die Härteprüfung nach Knoop festgelegt für Eindruckdiagonallängen ≥ 0,020 mm. Die Verwendung dieses Verfahrens zur Bestimmung der Knoop-Härte für kleinere Eindrücke gehört nicht zum Anwendungsbereich in diesem Dokument, weil die Resultate wegen Grenzen der optischen Messung und Unvollkommenheiten der Kegelgeometrie mit großer Unsicherheit behaftet wären. ISO 14577 1 erlaubt die Härte-Bestimmung von kleineren Eindrücken.
Eine periodische Überprüfung ist angegeben zur laufenden Kontrolle der Prüfmaschine in Betrieb durch den Anwender.
Besondere Überlegungen zur Prüfung metallischer Überzüge nach Knoop können ISO 4516 entnommen werden.
Matériaux métalliques - Essai de dureté Knoop - Partie 1: Méthode d'essai (ISO 4545-1:2017)
ISO 4545-1:2017 spécifie la méthode d'essai de dureté Knoop pour les matériaux métalliques, pour des forces d'essai comprises entre 0,009 807 N et 19,613 N.
Le présent document spécifie l'essai de dureté Knoop pour les longueurs de diagonale d'empreinte ≥ 0,020 mm. L'utilisation de cette méthode pour déterminer la dureté Knoop d'empreintes plus petites ne fait pas partie du domaine d'application du présent document, car les résultats ainsi obtenus présenteraient des incertitudes élevées en raison des limitations du mesurage optique et des imperfections concernant la géométrie de la pointe. L'ISO 14577‑1 permet de déterminer la dureté des empreintes plus petites.
Une méthode de vérification périodique est spécifiée pour la vérification de routine, par l'utilisateur, de la machine d'essai utilisée.
Des considérations particulières pour les essais Knoop des revêtements métalliques sont disponibles dans l'ISO 4516.
Kovinski materiali - Preskus trdote po Knoopu - 1. del: Preskusna metoda (ISO 4545-1:2017)
Ta dokument določa metodo za preskus trdote po Knoopu za kovinske materiale s preskusnimi silami od 0,009 807 N do 19,613 N.
Preskus trdote po Knoopu je v tem dokumentu določen za dolžine diagonal zarez ≥ 0,020 mm. Uporaba te metode za določanje trdote po Knoopu na podlagi manjših zarez ne sodi v področje uporabe tega dokumenta, saj bi bili rezultati nezanesljivi zaradi negotovosti, povezane z omejitvami optičnega merjenja in nepravilnostmi geometrije konice. Določevanje trdote na podlagi manjših zarez omogoča standard ISO 14577-1.
Določena je tudi metoda za redno preverjanje pri rutinskem pregledovanju naprave za preskušanje, ki jo uporablja
uporabnik. Posebne zahteve za preskušanje kovinskih prevlek so navedene v standardu ISO 4516.
