Analysis and assessment of the composition of a metal (5)

I believe the answer is:

assay

(Other definitions for assay that I've seen before include "Analyse ore for metal content" , "Examine chemicals" , "Check (a metal's) quality" , "Analyse to find the properties" , "Test ore for value" .)

I've seen this clue in The Irish Times.
