GOST – National standards Gosudarstvennye Standarty
Russian standards Gosstandart (GOST) cover more than 20 industrial branches including petroleum and chemical industry as well as mining and mineral sources, power and electrical equipment, oil and gas products. GOST organization, which was originally established during the Soviet Union era, was appointed to develop and put into practice state policy in the field of standardization. This institution was adopted by the Commonwealth of Independent States (CIS) and it is administrated by the Euro-Asian Council for Standardization, Metrology and Certification (EASC).
