Shocking punishment one won’t stand for (8,5)
I believe the answer is:
electric chair
'stand for' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
(Other definitions for electric chair that I've seen before include "Instrument of execution" , "US means of execution" , "Death row destination?" , "Device for execution in some US states" , "US form of execution" .)
