Standard means devised to produce cheese (8)
I believe the answer is:
parmesan
'cheese' is the definition.
(Parmesan is an example)
'standard means devised' is the wordplay.
'standard' becomes 'par' (I've seen this before).
'devised' indicates anagramming the letters.
'means' with letters rearranged gives 'mesan'.
'par'+'mesan'='PARMESAN'
'to produce' acts as a link.
(Other definitions for parmesan that I've seen before include "Italian cheese for spearman" , "that grates" , "Hard dry Italian cheese" , "Hard dry cheese, often grated" , "Pam earns this cheese" .)
