Automotive Wiring Harness Production
Wiring harness production governed by international standards so vehicle electrical systems work reliably: ISO 6722, ISO 14572, SAE J1128, LV 112, IPC/WHMA-A-620, ISO 16750 and RoHS.
Automotive wiring harness production is subject to a number of international standards that keep vehicle electrical systems safe, reliable and efficient. These standards define the safety, durability and performance of the cables.
Core standards we follow
ISO 6722 — Road vehicles, low-voltage cables
The base standard defining insulation material, temperature resistance, electrical properties and mechanical strength of automotive cables. It covers the production and use requirements for low-voltage cables (up to 60 V).
ISO 14572 — Insulation and cable surface coating
Governs the resistance of surface coatings and insulation materials to environmental factors such as heat, chemicals and humidity, so that the materials used in a harness last.
SAE J1128 — Low-voltage primary cable
Accepted in the US automotive industry, this standard defines the physical and electrical properties of low-voltage cable. Manufacturers producing for the US market develop products to this standard.
LV 112 — German automotive cable standard
Used by German vehicle manufacturers, this standard regulates the electrical and mechanical properties of wiring harnesses and guarantees their performance, durability and safety.
IPC/WHMA-A-620 — Cable and wire harness assembly
Defines quality and reliability criteria in harness production and guides production lines on connection points, soldering, protective coverings and test procedures.
ISO 16750 — Environmental conditions and testing
Specifies how a harness must perform against extreme temperature, vibration, humidity and other environmental factors. These tests secure durability and long service life.
RoHS — Restriction of hazardous substances
A directive restricting the use of certain hazardous substances in electrical and electronic components, ensuring that harness materials are environmentally sound and harmless to human health.
Together these standards form the guidance that automotive harness manufacturers must follow to secure both safety and vehicle performance.
