Abstract / scope

ISO 15093:2015 specifies an analytical procedure for the determination of either platinum in platinum jewellery alloys, gold in gold jewellery alloys, or palladium in palladium jewellery alloys, with a nominal content of each precious metal of 999 ? (parts per thousand) by measuring specific elements. (See Tables A.1, A.2, and A.3.)

ISO 15093:2015 specifies a method intended to be used as the recommended method for the determination of fineness in 999 ? alloys covered by ISO 9202.
