Source: SAE/USCAR-21 Revision 4 (2020), pull-out force indexed to wire cross-section; crimps must survive 15 years / 150,000 miles of thermal cycling (−40 °C to +125 °C). ZEUEE assembly + bending cells are engineered to hold seating consistency to a ±0.05 mm crimp-class tolerance so finished connectors clear these thresholds repeatably.
