What is the minimum size of a pressure vessel that requires ASME code certification? Citation of the code number or section would be useful. Thank you.

RE: Minimum Size for Coded Pressure Vessels
Section VIII Division I
U-1(i)(vessels having an inside diameter, width, height, or cross section diagonal not exceeding 6 in. (152 mm), with no limitation on length of vessel or pressure;
U-1(j)(3) 1.5 cu ft (0.04 m3) in volume and 600 psi (4.1 MPa) design pressure.

If it's relieved below 15 psig, it's "non code"- unless some other code applies (ie. big storage tanks). Owner's choice.
Higher than 15 psig but below ASME VIII's scope? It's a piece of B31.3 pipe.
