This document specifies the critical dimensions of valve cups suitable for clinching into 25,4 mm aperture metal aerosol containers.
This document is applicable to aperture metal aerosol containers which are used with the metal aerosol containers in accordance with EN 14847 and EN 15006.
This European Standard does not specify dimples on aperture metal aerosol containers.
NOTE To provide satisfactory filling in production, dimples are no longer considered essential but might still be used. Their presence could cause damage of the 25,4 mm aperture and their presence on lacquered cups can give rise to coating defects at the dimple feature. Thus, in the interest of simplicity and reduction of difficulties, dimples are excluded from this standard.
