BS EN 14848:2020,Aerosol containers – Metal containers with 25, 4 mm aperture – Dimensions of valve cups.
The specific dimensions of valve cups given in this document are recognized as critical in respect of closure efficiency. They are important to the manufacturer in process control and to the filler for incoming goods inspection and ultimately clinch setting and control.
Cups in tinplate, blackplate, stainless steel, aluminium and aluminium alloys are permitted by this standard but it is emphasized that the dimensions are independent of the material.
BS EN 14848:2020 specifies the critical dimensions of valve cups suitable for clinching into 25, 4 mm apertur emetal aerosol containers.
BS EN 14848:2020 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.
