JASO D611
JASO D611 is a Japanese automotive standard established by the Society of Automotive Engineers of Japan (JASO). It defines construction, performance, and testing requirements for low-voltage automotive wires, mainly used in 12V and 24V systems. The standard ensures stable and safe operation of electrical wiring in demanding vehicle environments.
The specification covers single-core wires applied in engine compartments, chassis wiring, interior electronics, and lighting systems. It evaluates insulation thickness, conductor resistance, heat resistance, cold flexibility, and chemical durability to guarantee reliability against temperature variations, mechanical stress, and exposure to fluids.
Under JASO D611, common wire types include AV, AVS, AVSS, and CAVUS, which differ in insulation wall thickness and current capacity. These wires are widely adopted by Japanese OEMs and Asian automakers, often referenced alongside ISO 6722 and SAE J1128 as global benchmarks for modern automotive wire harness design.
