Joaillerie, bijouterie — Dosage de l’argent dans les alliages d’argent pour la bijouterie-joaillerie — Méthode volumétrique (potentiométrique) utilisant le bromure de potassium
| Published By | Publication Date | Number of Pages |
| ISO | 2014-11 | 12 |
La méthode de l'ISO 11427:2014 décrit une méthode volumétrique de dosage de l'argent dans les alliages utilisés en bijouterie-joaillerie, compris de préférence dans les limites de titre indiquées dans l'ISO 9202.
Ces alliages peuvent contenir du cuivre, du zinc, du cadmium et du palladium. À part le palladium qu'il faut précipiter avant de commencer le titrage, ces éléments ne gênent pas le dosage.
La présente méthode est destinée à servir de référence pour la détermination du titre des alliages traités dans l'ISO 9202.
