[MW:4043] Transition (pup pipes) testing requirments

Pipelines are subject to the rigours of fracture control e.g. ductile
fracture via impact energy absorption and brittle fracture via shear
area fracture appearance. This is often done by CVN and DWT.

Should pup pieces made up from API 5L xx linepipe be subjected to the
same tests? Or should they by tested only via impact energy absorption
as are the fittings to which they are attached.
