Hi Rudolph,
A strain gage, as the name implies, measures strain, i.e. deformation.Thus,
for you  test to make sense, you need to exactly replicate what you do during
ICT.
The most common copper foilis E1 in IPC-CF-150 [not 152]; the document has
since been renumbered to IPC-xxxx [do not know the new number off-hand]. E1
is the lowest quality copper foil.
What you would need to compare your strain gage results to is the ductility
of the foil used--ductility values are not provided by the vendors and they
can vary considerably [see IPC-TR-484].
