Harnesses must be validated not just for continuity, but for dielectric withstand (Hi-Pot) and mechanical resilience.
Destructive vs Non-Destructive
Crimp pull-force is destructive and sampled (e.g. 5 per shift). Hi-Pot testing is non-destructive and applied 100% to line output.
3. Continuity Fault Finder
Identify if a measured resistance implies a broken strand.

Common Mistakes in Harness Testing Procedures
- Assuming static theoretical values over empirical testing.
- Ignoring thermal derating curves in enclosed routing spaces.
- Applying generic global standards without cross-referencing European ISO 6722 limits.
Frequently Asked Questions
What is the primary standard for this?
Typically governed by IPC/WHMA-A-620 for manufacturing and ISO 6722 for the physical wire attributes.
How frequently should tools be calibrated?
At least every 50,000 cycles, or per shift for high-volume automated lines.
