For wiring harnesses two types of testing are carried out :
1. On Line i.e. Routine and
2. Performance / Endurance i.e. Non-Routine Tests
Online (Routine)
During production there is:
-
100% circuit checking for fitment & electrical continuity
-
100% visual checking for verifying critical parameter
Performance / Endurance (Non-Routine Tests)
These are of the following types :
-
Electrical
-
Mechanical
-
Environmental
-
Endurance
