Testing and inspection standards for automotive wiring harnesses

Automobile wiring harness is the main body of the automobile circuit network, and there is no automobile circuit without wiring harness. In recent years, with the rapid development of new energy vehicles and smart cars, the market's demand for automotive wiring harnesses has also grown greatly. However, with the increase in demand, the requirements for product quality have also reached new heights. So what kind of wiring harness products meet the acceptance standards of major OEMs? Today, Fabio Labs will introduce the standard ISO14572-2011-"Shielded or unshielded single-core or multi-core wires for road vehicles-Basic and high-performance wires test methods and requirements interpretation"

ISO 14572-2011: Road vehicles — Round, sheathed, 60 V and 600 V screened and unscreened single- or multi-core cables — Test methods and requirements for basic- and high-performance cables

ISO 14572-2011: Road vehicles -60V and 600V shielded or unshielded single-core or multi-core wires-basic and high-performance wire test methods and requirements.

The main test items are as follows:
1. Visual appearance
2. Outside cable diameter
3. Ovality of sheath
4. Thickness of sheath
5. Electrical continuity
6. Withstand voltage
7. D.C resistance of the screen ISO 14572 Section 6.3.2
8. Screening effectiveness (Line injection)
9. Screening effectiveness (Tri-axial method)
10. Screening effectiveness (Absorbing clamp method)
11. Pressure test at high temperature
12. Adhesion of sheath
13. Cyclic bending
14. Winding at low temperature
15. Impact at low temperature
16. Resistance to abrasion
17. Long-term heat ageing, 3000 h
18. Short-term heat ageing, 240 h
19. Thermal overload
20. Shrinkage by heat of sheath
21. Resistance to chemicals
22. Durability of sheath marking
23. Resistance to ozone
24. Temperature and humidity cycling
25. Resistance to flame propagation
26. Artificial weathering
