(in Russian – ГОСТ 17022-81 Графит. Типы, марки и общие технические требования)

This standard applies to graphite obtained from graphite ores and waste from metallurgical and other industries and establishes types, grades, general technical requirements.

Depending on the mineralogical type and type of consumption, graphite is produced in the following grades:

Special graphite with low ash content (in Russian – Графит специальный малозольный)
(mineralogical type – crystalline)
Marks:
GSM-1 (ГСМ-1), GSM-2 (ГСМ-2) (for export and production of special purpose products).

Graphite for the preparation of alcaline accumulator active mass (in Russian – Графит аккумуляторный)
(mineralogical type – crystalline)
Marks:
GAK-1 (ГАК-1) (for battery products for special purposes).
GAK-2 (ГАК-2) (for the manufacture of active masses and alkaline batteries, and masses for graphitized antifriction products from non-ferrous metals).
GAK-3 (ГАК-3) (for the manufacture of masses for graphitized antifriction products from non-ferrous metals).

Graphite for manufacture of slate-pencils (in Russian – Графит карандашный)
(mineralogical type – crystalline)
Marks:
GK-1 (ГК-1) (for drawing and stationery pencils).
GK-2 (ГК-2), GK-3 (ГК-3) (for stationery, school and copy group pencils).

Graphite of lubricants (in Russian – Графит смазочный)
