The following standards are used for specifying the requirements for aluminium die castings:
DIN 1688 Part 4 LIGHT METAL ALLOY RAW CASTINGS; PRESSURE DIE CASTINGS; GENERAL TOLERANCES, MACHINING ALLOWANCES
DIN EN 1706 ALUMINIUM AND ALUMINIUM ALLOYS - CASTINGS - CHEMICAL COMPOSITION AND MECHANICAL PROPERTIES
ASTM B 85 STANDARD SPECIFICATION FOR ALUMINUM-ALLOY DIE CASTINGS
I am not sure what you meant by "english" norms, but BS EN 1706 has the same content as DIN EN 1706 except the language is English not German. BS is the official standards organization in the United Kingdom.
