Conseils généraux
Valeur de correction Rockwell pour les essais sur échantillons cylindriques
Si un essai Rockwell est effectué sur un échantillon cylindrique, il convient d’ajouter au résultat de mesure les valeurs de correction suivantes – en fonction du rayon de courbure de l’échantillon ainsi que de l’échelle Rockwell utilisée – en raison de la faible résistance de la surface d'essai au pénétrateur (selon ISO 6508-1).
