AS 1856-2004

This Standard specifies requirements for the electrodeposited coatings of silver used for engineering purposes that may be matt, bright, or semi-bright and are not less than 98 percent silver purity. The requirements also specify thickness, quality and testing of electroplated coatings of silver on metallic and non-metallic materials for decorative, protective, electrical contact characteristics, high electrical and thermal conductivity, thermocompression bonding, wear resistance of load-bearing surfaces, spectral reflectivity, solderable surfaces and other general engineering applications.
