I am commenting here purely on the practicalities of component life, NOT any process that is, or has been, in place.
Explosive components are lifed by manufactured lots. Period. If batch testing is carried out to extend lives, then the operational environment may sometimes be taken into account - but usually to the detriment of the life. Batch testing is carried out by approved establishments, in proper process buildings, using scientific methods, and not by some clever cloggs who thinks "it'll do a trip". Anyone who installs explosive cartridges that are life ex needs their tool kit confiscated. Authorisers who ignore life dates should seek alternative employment. Bending the rules gets people killed.
