Upholder of standards? (8)
I believe the answer is:
flagpole
'upholder of standards?' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for flagpole that I've seen before include "means to raise standard" , "Ceremonial mast" , "Upholder of standards" , "Mast on which banner is hoist" , "Pin" .)
