GOST/ГОСТ 12820-80 FLANGE PN1.6MPa PLATE RF

 GOST (Russian: ГОСТ) refers to a set of technical standards maintained by the Euro-Asian Council for Standardization, Metrology and Certification (EASC), a regional standards organization operating under the auspices of the Commonwealth of Independent States (CIS).
All sorts of regulated standards are included, with examples ranging from charting rules for design documentation to recipes and nutritional facts of Soviet-era brand names (which have now become generic, but may only be sold under the label if the technical standard is followed, or renamed if they are reformulated).
The notion of GOST has certain significance and recognition in the countries of the standards’ jurisdiction. Russian Rosstandart government agency has gost.ru as website address.
