Method of detecting a potentially void inhaler can valve ( 30 ), which valve ( 30 ) is attached to a can ( 10 ) by a ferrule crimp ( 80 ), comprising the steps: placing the can ( 10 ) in a can jig ( 220 ) that is arranged to retain the can ( 10 ) at a predetermined measurement height with respect to a diameter measuring means ( 230 ), measuring the diameter of the ferrule crimp ( 80 ) at the predetermined height, and comparing the measured crimp diameter with a predefined interval of acceptance, and if the measured diameter is outside a predefined interval classifying the inhaler can valve ( 30 ) as potentially void. There is also provided a crimp diameter measuring device ( 200 ) comprising: a base ( 210 ), a diameter measuring means ( 230 ) supported by the base ( 210 ), and a can jig ( 220 ) supported by the base ( 210 ), the can jig ( 220 ) being arranged to retain a can ( 10 ) placed therein at a predetermined measurement height with respect to a diameter measuring means ( 230 ).
