Produits carbonés utilisés pour la production de l'aluminium — Brai pour électrodes — Partie 2: Détermination du point de ramollissement (Point de ramollissement par la méthode Mettler)

ISO 5940-2:2007 specifies a method to determine the softening point of pitches by the Mettler method, within the range of 50 °C to 180 °C.

It can be used for other organic materials that are used as binder and impregnating agents, where they have a Mettler softening point within the range of 50 °C to 150 °C.
