| 118 | The mechanical figure of merit is ''residual seal force'': the compressive force remaining on the stopper after crimping and after the elastomer has relaxed. Too little leaves an unreliable seal; too much can distort the stopper, damage the glass sealing surface or crack the flange. Residual seal force is measurable non-destructively and has become the conventional in-process control for capping, replacing subjective assessments such as attempting to rotate the cap by hand.{{r|kirsch1997,usp1207}} | 118 | The mechanical figure of merit is ''residual seal force'': the compressive force remaining on the stopper after crimping and after the elastomer has relaxed.

| + | 120 | Ferrule designs differ in how the closure is later opened. A plain ferrule fully covers the stopper and must be removed with a decapping tool. A flip-off design carries a plastic button over a pre-cut aperture, which is lifted away to expose the central area of the stopper for needle penetration while leaving the crimp intact — the arrangement almost universal for injectable products and for research peptide vials. Colour of the button is a manufacturer's identification device with no standardised meaning, and it is not a reliable indicator of contents.{{r|iso8362_5}} | |
