    Abstract - (Show below) - (Hide below)

    This Standard sets out gravimetric procedures for the determination of silver content in the range 1 % to 99 % in silver and silver bearing alloys with < 2 % nickel, < 0.05 % rhodium, < 0.05 % tungsten, < 1 % platinum and < 3 % palladium.

    Scope - (Show below) - (Hide below)

    This Standard sets out gravimetric procedures for the determination of silver content in the range 1 % to 99 % in silver and silver bearing alloys with < 2 % nickel, < 0.05 % rhodium, < 0.05 % tungsten, < 1 % platinum and < 3 % palladium.
    NOTE 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 and the platinum and palladium quantified using AS 4119.
    NOTE 2 Recommended methods of sampling bullion for use with this Standard are provided in Appendix A.
    NOTE 3 The presence of the following elements may cause difficulties in obtaining a homogeneous sample: iron, lead, antimony, nickel or arsenic.
