University working with means of lifting national standard (5,4)
I believe the answer is:
union jack
'national standard' is the definition.
(flag of the United Kingdom)
'university working with means of lifting' is the wordplay.
'university' becomes 'uni' (I've seen this before).
'working' becomes 'on'.
'with' says to put letters next to each other.
'means of lifting' becomes 'jack' (tool used to lift or raise something).
'uni'+'on'+'jack'='UNION JACK'
(Other definitions for union jack that I've seen before include "standard for us" , "Colours" , "National flag of United Kingdom" , "The British flag" , "UK's standard" .)
