PWHT soaking time for CS Pipe Trunnion

Gents,

I have doubt regarding the PWHT Soaking time for Carbon steel pipe Trunnion
as per ASME B31.3 Minimum PWHT is require for Tb+tc or Tr+tc > 2times min req thickness(40mm) - governing thickness

Please advise which reference ASME paragraph mention specific for minimum soaking time for above pipe trunnion ( governing thickness ) ?

Regards,
Eko
