APPENDIX A: Stopper Testing and Verification



Visually inspect the stopper for

weak spots and integrity.

Discard stopper if weak spots are found.

Continue with inspection if everything looks OK.

OK Examples:

Coating is coming off, but individual threads are not showing.

Bad Examples:

Discard stoppers shown below since individual threads are exposed, starting to fray, and loose from coating.
