Silver and silver bearing alloys Determination of silver content (1% to 99%) - Gravimetric (fire assay) method
Standards Australia
Sets out a gravimetric (fire assay) procedure for the determination of silver content in silver bearing alloys. This method is applicable to alloys containing 1% to 99% silver and less than 2% nickel, 0.05% rhodium and 0.05% tungsten.

This Standard sets out a gravimetric procedure (fire assay) for the determination of silver content in silver bearing alloys. This method is applicable to alloys containing 1% to 99% silver and less than 1% platinum, 3% palladium, 2% nickel, 0.05% rhodium and 0.05% tungsten.
NOTES:
1 If gold, platinum or palladium are present they are retained with the silver. Consequently they need to be quantified and the silver content appropriately adjusted. The gold content can be quantified using AS 3515.1 or AS 3515.2 as appropriate.
2 Recommended methods of sampling dore bullion for use with this Standard are provided in Appendix A.
3 The presence of the following elements may cause difficulties in obtaining a homogeneous sample: iron, lead, antimony, nickel or arsenic.
