Jewellery and precious metals - Determination of palladium - ICP-OES method using an internal standard element (ISO/DIS 11495:2026)
Käsitlusala: This document specifies an analytical method for the determination of palladium on a material considered homogeneous. The palladium content of the samples lies preferably between 50 ‰ (parts per thousand) and 990 ‰ (parts per thousand). Fineness above 990,0 ‰ can be determined using a spectroscopy method by difference ISO 15093.
NOTE Lower contents of palladium can be analysed referring to this method.

Jewellery and precious metals - Determination of platinum - ICP-OES method using an internal standard element (ISO/DIS 11494:2026)
Käsitlusala: This document specifies an analytical method for the determination of platinum on a material considered homogeneous. The platinum content of the samples lies preferably between 50 ‰ (parts per thousand by mass) and 990 ‰ (parts per thousand by mass). Fineness above 990,0 ‰ (parts per thousand by mass) can be determined using a spectroscopy method by difference ISO 15093.
