I will say IPC TM-650, Method 2.6.27. Not knowing what you meant by the
term shock, this TM simulates the stress of thermal excursions
experienced by the printed board during reflow processing.

Folks,
As I understand the above mentioned Test Method is reserve for PTH
product/boards. What application is used when all of the PTH are
filled with non conductive maters, plated over, planarized and covered
with solder mask. I don't see how the above test would shock the IP
layers.
"X"
