If I design piping for B31.1 or B31.3 - 2010ed - allowable stress for hydro test is 0.9*Sy & Sy.

When I design WRC-107 or NozzlePro & code is same as above, what are allowable stresses for Pm & Pm+Pl+Qb as per ASME Sec VIII Div-2 ?

Is it OK to have these higher allowable without testing requirements as per Sac VIII Div 2 ?

This I am asking in connection with the use of large bore pipe test blind with cris-cross stiffners.
