Refined Platinum State Standard (Reference) Material GSO 8434-2003
GSO of refined platinum composition can be applied in analytical laboratories carrying out noble metals analysis and certification tests for deviation control of measurements methods to determine impurities content in platinum ÏëÀ-0; ÏëÀ-1, ÏëÀ-2, as per GOST 12341-81; Ïë 999.8, Ïë 999.5, as per GOST R 51704-2001 and ÏëÀï-0, ÏëÀï-1, ÏëÀï-2, as per GOST 14837-79.
GSO standard materials of platinum composition have been manufactured from one cast, made by the method typical that of JSC Krastsvetmet’s finished production.
The material was attested by an interlaboratory experiment, with 7 appropriately accredited laboratories involved.
The attested GSO characteristics are: palladium, rhodium, iridium, ruthenium, lead, gold, iron, silicon, tin, aluminum, antimony, silver, copper, nickel, magnesium, zinc, bismuth, calcium, manganese, molybdenum and chrome.
The information on GSO 8434-2003 is included in the COMAR database for certified reference materials.
