is a former Soviet and interstate standard that established the technical requirements for aluminum casting alloys, including their grades, chemical compositions, and mechanical properties . While it has largely been superseded by more modern standards like GOST 1583-89 , it remains a critical reference for legacy engineering projects, spare part manufacturing, and historical technical documentation.
