Strands too twisted Insulation scraps on stripped wire
Strands not twisted
Damaged insulation Insulation badly cut Strands damaged by stripping tool
Strands crushed by insulation barrel
Wire stripping too short Loose strands
Wire stripping too long Insulation crimped by wire barrel
Check and evaluationsAcceptable
Wire section too small
Insulation pierced by insulation barrel
Insulation pierced by insulation barrel
Insulation barrel not correctly closed Wire section too big Insulation barrel not
correctly shaped ans closed
Insulation barrel too tight
Insulation barrel not coorectly closed
Measuring the Crimp height (micrometer)
Retention test = depend of the contact
Crimping not symmetrical
Excess of material extrusion
Wrong or damaged anvil
Crushing not correct, shapeless
wire barrel's bottom
Wire section too big
Unadequate compacting
Wire section too small
Distance between crimp face ends
Formation of cracks in the crimp base
Big burr unacceptable
Control 1 to 7 must be done in case of doubt in visual control inspection of the crimping quality + all 300 000 cycles + change of
elements of crimping + new applicator.

Measuring the Crimp width (cross section)
H/W ratio et compaction of crimping
compaction crimpingThe ration H/W is acceptable when the result is between 55% (min) and 70% (max)--> This criterion is conform in case when H and W defined in the control sheet are respected.
Fc ≥0,5 x S3 CFE ≤ 0,5 x S4
Sb ≥ 0,75 x S7
For the crimping is conform:
- - Bh ≤ S
- Bw ≤ 0.5 X S
- None cracking is accepted

Stripping length precisely set and cutThe wire stripped section must be undamaged The wire stripped section must be clean and free of insulation scrapsGripping marks on insulation are allowed
Insulation wire
Both wire and insulation must be clearly visible
Insulation barrel correctly closed
Insulation barrel correctly shaped and closed
Insulation barrel correctly aligned and closed
The crimping is symmetrical. The strands are uniformly compacted, there are no empty spots.
There's no material extrusion and/or terminal deformation. The flat spots are clearly visible and aligned
Flat spot Flat spot
The flat spots are an important mark of the anvil on the terminal bottom, they help with the strands compacting and keep the terminal aligned with the anvil itself
