Jewellery and precious metals - Determination of palladium - Gravimetry using dimethylglyoxime (ISO 11490:2023)
This document specifies a gravimetric method for the determination of palladium in palladium alloys. The palladium content of the sample lies preferably between 50 and 999 parts per thousand (‰). Fineness above 999 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15093).
This method is also intended to be used as one of the recommended methods for the determination of fineness in jewellery alloys covered by ISO 9202.
Schmuck und Edelmetalle - Bestimmung von Palladium - Gravimetrie mittels Dimethylglyoxim (ISO 11490:2023)
Dieses Dokument legt ein gravimetrisches Verfahren für die Bestimmung von Palladium für ein als homogen angesehenes Material fest. Der Palladiumgehalt der Probe liegt vorzugsweise zwischen 50 und 999 Massenteilen je Tausend (‰). Der Feingehalt über 999 ‰ kann mit einem spektroskopischen Differenzverfahren (z. B. ISO 15093) bestimmt werden.
Dieses Verfahren ist als eines der empfohlenen Verfahren für die Bestimmung des Feingehalts von Schmucklegierungen nach ISO 9202 vorgesehen.
Joaillerie, bijouterie et métaux précieux - Dosage du palladium - Méthode gravimétrique utilisant la diméthylglyoxime (ISO 11490:2023)
Le présent document spécifie une méthode gravimétrique de dosage du palladium sur un matériau considéré homogène. La teneur en palladium de l’échantillon est de préférence comprise entre 50 et 999 millièmes (‰) en masse. Les titres supérieurs à 999 ‰ peuvent être déterminés à l’aide d’une méthode de spectroscopie par différence (par exemple ISO 15093).
Cette méthode est également destinée à être utilisée comme l’une des méthodes recommandées pour la détermination du titre dans les alliages pour la bijouterie-joaillerie couverts par l’ISO 9202.
Nakit in plemenite kovine - Določevanje paladija - Gravimetrija z dimetilglioksimom (ISO 11490:2023)
Ta dokument določa gravimetrično metodo za določevanje paladija v zlitinah paladija. Vsebnost paladija v zlitinah bi morala biti med 50 in 999 delov na tisoč (‰). Finost nad 999 ‰ je mogoče določiti z metodo spektroskopije glede na razlike (npr. standard ISO 15093).
Metoda je namenjena tudi za uporabo kot priporočena metoda za določanje finosti v zlitinah za nakit, ki je zajeta v standardu ISO 9202.
