AS 3515.3:2019 PDF

This Standard sets out a gravimetric procedure for the determination of gold content in gold alloys. This method is applicable to gold and gold alloys containing more than 99.5 % gold and < 0.05 % rhodium and < 0.05 % tungsten.

This Standard was prepared by Standards Australia Committee CH-010, Analysis of Metals, to supersede AS 3515.3—2002, Gold and gold bearing alloys, Part 3: Determination of gold content (greater than 99.5%)—Gravimetric (fire assay) method.

This Standard is part of a series for AS 3515, as follows:

AS 3515.1, Gold and gold bearing alloys, Part 1: Determination of gold content (Less than 30 %) — Gravimetric (fire assay) method

AS 3515.2, Gold and gold bearing alloys, Part 2: Determination of gold content (30% to 99.5%)— Gravimetric (fire assay) method

AS 3515.3, Gold and gold bearing alloys, Part 3: Determination of gold content (greater than 99.5 %) — Gravimetric (fire assay) method (this Standard)

AS 3515.4, Gold and gold bearing alloys, Part 4: Determination of gold content (greater than 99.95%)— Inductively coupled plasma—Atomic emission spectrometry
