AMS Specification for Shot Peening, Ultrasonically Activated with the number AMS2580A states that "In some circumstances, where Almen strip measurements cannot be performed, a coupon made of the same material as the part may be used to characterize the peening" in paragraph

■ Is there a procedure for this purpose?
■ Does "saturation" matter still when residual stress meausurement is in charge?
■ How could this paragraph be applied if there is only Almen intensity requirement on blueprint?

Thanks in advance for your responses,
