Lust and ardour's about normal (8)

I believe the answer is:

standard

'normal' is the definition.
('standard' is associated in meaning with 'normal')

'lust and ardour's about' is the wordplay.
'about' indicates the answer is hidden within the clue.
'STANDARD' is hidden within 'lust and ardours'.

(Other definitions for standard that I've seen before include "Normal, average" , "Flag - accepted level" , "type of flag" , "Stock - basic - flag" , "Grade" .)

I've seen this clue in The Telegraph.
