DESCRIPTION

BS EN ISO 11427:2024 - TC

This standard BS EN ISO 11427:2024 - TC Tracked Changes. Jewellery and precious metals. Determination of silver. Potentiometry using potassium bromide is classified in these ICS categories:

39.060 Jewellery

This document specifies a volumetric method for the determination of silver on a material considered homogeneous. The silver content of the sample lies preferably between (100 and 999,0) parts per thousand (‰) by mass. Fineness above 999,0 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096). This method is intended to be used as the reference method for the determination of fineness in alloys covered by ISO 9202.
