RE: Is there any Europe Standards and US standards define the BFV leakage rate?
API 598 covers: Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant.
It might help if you provide more information about what you're needing.

RE: Is there any Europe Standards and US standards define the BFV leakage rate?
I'm not aware of any leakage test standard defining acceptance criteria based on valve type only, and I believe this in not by chance, because “the required leak tightness shall be related to the function of the object under consideration” (as also EN 1779 standard says, for instance).
