Pipe Impact testing after bending

Pipe Impact testing after bending

Pipe Impact testing after bending

Hello Everyone,
During my work i came across one question.
Pipe of 16Mo3 (DIN EN 10216-2, 2020) size DN 250 Sch. 40 (9.27 mm)
Bend Radius = 1440 mm
Bend Angle = 60 Deg.

Which process shall be followed, hot forming or Cold forming..?
should it be impact tested after bending ?
This material is already impact tested before bending according to ASME Sec. III NB-2300.
Should i take exemption according to NB-4213 from impacting testing after bending using cold forming procedure.

Can anyone please guide me...?

Thanks & Regards.
