适用范围：The document specifies a gravimetric method for determining platinum in platinium jewellery alloys, proferably within the range of fineness as stated in ISO 9202. This procedure applies specifically to platinum alloys incorporating iridium, palladium, gold, rhodium, copper, cobalt, ruthenium, gallium, chromium, indium and less than 5 % tungsten. Some modifications are indicated whrere palladium, gold, ruthenium, iridium or rhodium are present.#,,#
