AS 5006.1:2019 PDF

This Standard sets out a titrimetric procedure for the determination of silver content in silver and silver bearing alloys in the range 0.1 % to 99.9 % silver with < 20 % gold and platinum group metals.

This Standard was prepared by Standards Australia Committee CH-010, Analysis of Metals, to supersede AS 5006.1—2002, Silver and silver bearing alloys, Part 1: Determination of silver content (0.1% to 99.9%)—Titrimetric (potentiometric) method.

The objective of this Standard is to set out a titrimetric method for the determination of silver content in silver and silver bearing alloys in the range 0.1 % to 99.9 % silver with < 20 % gold and platinum group metals. If palladium or tungsten are present they need to be complexed. This method is not suitable for alloys containing mercury.

This Standard is Part 1 of a series comprising:

AS 5006.1, Silver and silver bearing alloys, Part 1: Determination of silver content (0.1% to 99.9%)— Titrimetric (potentiometric) method (this Standard)

AS 5006.2, Silver and silver bearing alloys, Part 2: Determination of silver content (1% to 99%)— Gravimetric (fire assay) method
