Set of standards covering a German drug (7)
I believe the answer is:
codeine
'set of standards' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'covering a german drug' is the wordplay.
'covering' becomes 'cod' (cod is a kind of covering**).
'a german' becomes 'ein' ('a' in German).
'drug' becomes 'e' (e is another name for ecstasy).
'cod'+'ein'+'e'='CODEINE'
Can you help me to learn more?
(Other definitions for codeine that I've seen before include "Common opium-based tablet used to relieve pain" , "Derivative of opium used as an analgesic" , "Morphine-derived analgesic; die once (anag.)" , "Painkiller derived from opium" , "Niece, do take this drug" .)
