Which standard covers malleable iron threaded fittings?

Explanation:
ASME B16.3 is the standard for cast fittings, including malleable iron threaded fittings. It specifies the requirements for threaded fitting types and their dimensions, which is exactly what you need when selecting malleable iron threaded components for sprinkler piping. The other standards cover different things: B16.5 is about flanges and flange fittings, B36.10M covers dimensions for wrought steel pipe, and A17.1 is an elevator safety code, not related to piping fittings.
