Examined, tried (6)
I believe the answer is:
tested
This clue is a double definition.
'examined' is the first definition.
('test' can be a synonym of 'examine')
'tried' is the second definition.

(Other definitions for tested that I've seen before include "Subjected to examination, put through paces" , "In repose" , "Trialled" , "Put through a trial" , "Examined for quality or reliability" .)
