Automotive wiring harnesses constitute the primary network of a vehicle's electrical circuit, without which the automotive electrical system cannot exist. In recent years, with the rapid development of new energy vehicles (NEVs) and smart cars, market demand for automotive wiring harnesses has surged significantly. However, alongside this increased demand, product quality requirements have also risen to new heights. What then constitutes a wiring harness product that meets the acceptance standards of major automotive manufacturers? Today, Falab Laboratory will provide an interpretation of the standard 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."
