GOST 2685-75 is a state standard approved by the USSR State Committee for Standards (Gosstandart). It was officially introduced on January 1, 1977, following the decree No. 2908 dated November 14, 1975. The standard focuses on aluminum casting alloys intended for the production of shaped castings. It covers everything from alloy grades and chemical composition to technical requirements and testing methods.

: Specific impurity limits, such as iron content, are strictly defined for these methods.
