珠宝和贵金属-银的测定-使用溴化钾的电位滴定法

STANDARD by International Organization for Standardization, 04/01/2024.

LANGUAGES: English+Chinese【英文原文+中文翻译】

Description：

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.

适用范围 :

This International Standard method describes a volumetric method for the determination of silver in

jewellery alloys, preferably within the range of fineness stated in ISO 9202.

These alloys may contain copper, zinc, cadmium, and palladium. Apart from palladium, which must

be precipitated before commencing titration, these elements do not interfere with this method of

determination.

This method is intended to be used as the referee method for the determination of fineness in alloys

covered by ISO 9202.
