Abstract
1 Scope This International Standard specifies a gravimetric method for the determination of platinum in platinum jewellery alloys, preferably within the range of fineness stated in ISO 9202. These alloys can contain palladium, iridium, rhodium, copper, cobalt, gold, ruthenium, gallium, chromium, indium, and less than 5 % tungsten. Some modifications are indicated where palladium, iridium, rhodium, gold, or ruthenium are present.
