Jewellery - Determination of platinum in platinum jewellery alloys - ICP-OES method using yttrium as internal standard element
ISO 11494:2014 describes a method for the determination of platinum in platinum jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma optical emission spectrometry (ICP-OES). This method applies to platinum jewellery alloys that might contain silver, indium, iridium, gallium, copper, cobalt, nickel, tin, and ruthenium. However, this list is not exhaustive and care is always to be taken to investigate potential interference effects.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
