Title (German)

Schmuck - Bestimmung von Platin in Platin-Schmucklegierungen - Gravimetrische Bestimmung durch Fällung als Diammoniumhexachloroplatinat (ISO 11210:2014); Deutsche Fassung EN ISO 11210:2016

Overview

This document specifies a gravimetric method for the determination of platinum in platinum jewellery alloys, preferably within the range of fineness stated in ISO 9202. These alloys can contain palladium, iridium, rhodium, copper, cobalt, gold, ruthenium, gallium, chromium, indium, and less than 5 % tungsten. Some modifications are indicated where palladium, iridium, rhodium, gold, or ruthenium are present. This document (ISO 11210:2014) has been prepared by Technical Committee ISO/TC 174 "Jewellery" (secretariat: DIN, Germany) of the International Organization for Standardization (ISO) and shall now be adopted as EN ISO 11210:2016. The responsible German standardization committee is Working Committee NA 027-04-04 AA "Analysenmethoden zur Bestimmung des Feingehalts von Edelmetallen" ("Methods of analysis for determination of fineness of precious metals") at DIN Standards Committee Optics and Precision Mechanics (NAFuO).
