OS GSO ISO 11489:2008 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.
The procedure applies specifically to platinum alloys
incorporating Palladium, iridium, rhodium, topper,
Cobalt, gold, ruthenium, gallium, chromium, indium
and less than 5 % tungsten. Some modifications are
indicated where Palladium, iridium, rhodium, gold or
