(Main)Jewellery - Determination of palladium in palladium jewellery alloys - Gravimetric determination with dimethylglyoxime (ISO 11490:2015)
Jewellery - Determination of palladium in palladium jewellery alloys - Gravimetric determination with dimethylglyoxime (ISO 11490:2015)
ISO 11490:2015 specifies a gravimetric method for the determination of palladium in palladium jewellery alloys, preferably within the range of fineness stated in ISO 9202.
These alloys may contain silver, indium, gallium, copper, cobalt, nickel, tin, and ruthenium. Coprecipitated elements have to be determined by a suitable method and a correction applied.
Schmuck - Bestimmung von Palladium in Palladium-Schmucklegierungen - Gravimetrische Bestimmung mit Dimethylglyoxim (ISO 11490:2015)
Diese Internationale Norm legt ein gravimetrisches Verfahren zur Bestimmung von Palladium in Palladiumschmucklegierungen fest, vorzugsweise innerhalb eines Reinheitsbereichs wie in ISO 9202 festgelegt.
Diese Legierungen dürfen Silber, Indium, Gallium, Kupfer, Kobalt, Nickel, Zinn und Ruthenium enthalten. Mitgefällte Elemente sind mit einem geeigneten Verfahren zu bestimmen und durch eine Korrektur zu berücksichtigen.

Introduction
The following definitions apply in understanding how to implement an ISO International Standard and
other normative ISO deliverables (TS, PAS, IWA):
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” is used to indicate that something is permitted;
— “can” is used to indicate that something is possible, for example, that an organization or individual
is able to do something.
ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.1 defines a requirement as an “expression in the
content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed
and from which no deviation is permitted.”
ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.2 defines a recommendation as an “expression in the
content of a document conveying that among several possibilities, one is recommended as particularly
suitable without mentioning or excluding others, or that a certain course of action is preferred, but not
