Gold Alloy State Standard Materials GSO 8754-2006 – GSO 8763-2006

In 2006 10 types of Gold Alloy State Standard Materials were developed.

Gold Alloy State Standard materials are applied for analytical controlling of metrological equipment in gold bearing ores mining and processing and for analytical laboratories of metallurgical works and gold mines to carry out analysis and certification testing.

State standard material is gold, silver and copper alloy (gold purity being not less than 99.99%) as per GOST 28058-89, that of silver not less than 99.99 as per GOST 28595-90 and of copper not less than 99.905 as per GOST 859-2001). At present Gold Alloy GSO paperwork is being processed to be included in International Standard Reference Materials Lists.

Gold Alloy GSO samples can be manufactured as wire of 1 mm diameter; sheet segments of 0.3 – 0.4 mm thickness, 20, 30,40 mm wide; disks of 0.3-0.4 mm. GSOs as chips are supplied with weight not less than 10 g.
