21、 Sweden, Switzerland and United Kingdom. EN 14847:2005 (E) 4 Introduction The specific dimensions of 25,4 mm aperture tinplate aerosol containers given in this standard are recognized as critical in respect of closure efficiency. They are important to the manufacturer in process control and to the f
22、iller for incoming goods inspection and ultimately clinch setting and control. Radii and angles in the contact area of the clinch are affected by the destructive examination of containers required to check them. Specification of these dimensions has therefore been abandoned in favour of contour defi
23、nition in terms of inside and outside diameters and also contact height and shoulder height. EN 14847:2005 (E) 5 1 Scope This European Standard specifies the following dimensions of tinplate metal aerosol cans with 25,4 mm aperture: contact height, outside diameter, inside diameter and shoulder heig
24、ht. It is intended to be used with EN 14848 for clinching with valve cups. 2 Normative references The following referenced documents are indispensable for the application of this document.

Measure the contact height
27、 at 3 equidistant points around the aperture of each test can using the method given in EN 14850. Record the mean value of the contact height (i.e. the arithmetic mean of the 3 values), together with maximum and minimum values. The difference between the 3 values measured on the same can shall not b

Record the mean value of outside diameter (i.e. arithmetic mean of 3 values) togethe
