Allgemeine Tipps
Mindestabstand zwischen Prüfpunkten bzw. zur Probenkante
In den jeweiligen Normen der verschiedenen Prüfverfahren sind Mindestabstände zwischen den Prüfpunkten (Eindrücken) sowie zur Probenkante definiert. Der Grund dieser Mindestabstände liegt darin, dass Verfälschungen der Härteergebnisse, welche aus der Verformung bzw. Deformierung des Materialgefüges resultieren, vermieden werden sollen.
Für die Verfahren Rockwell (lt. ISO 6508), Brinell (lt. ISO 6506), Vickers (lt. ISO 6507) und Knoop (lt. ISO 4545) gelten die Mindestabstände in den untenstehenden Grafiken.
