A crimp is a gas-tight metal joint made in a tenth of a second. Everything you will ever know about it comes from a handful of checks — chosen well or chosen badly.
Crimped terminations fail slowly and inconveniently: a joint that passes continuity today can heat, oxidize and open a year later under vibration. Because the failure is delayed, the only real defence is process control at the moment of crimping.
The routine checks are pull-off force, crimp height and visual inspection against the terminal specification. Pull-off catches gross under-crimping. Crimp height catches drift in the tooling before it becomes a failure. Visual catches the things neither number sees: stray strands, insulation in the conductor barrel, a bell-mouth that is missing or excessive.
Where a program justifies it, a cross-section shows what the others infer — compaction, strand deformation, the absence of voids. It is destructive and slow, so it belongs at tooling qualification and at agreed intervals, not on every batch.
The discipline that matters most is the least technical: tooling verification on a schedule, with the results recorded against the work orders they cover. A crimp tool that drifted three weeks ago is a batch you can identify. A crimp tool with no verification history is a fleet-wide question mark.
